These occupy mountain valleys, and usually melt away before reaching the lowlands or the sea. Work of Glaciers. The rock waste — sand, pebbles, and even large masses of rock — under a glacier becomes embedded in the ice and is dragged forward by the gla- cier, scratching, polishing, and wearing away the bed rock beneath.
Rock waste also rolls down on the surface of valley glaciers from the mountain sides. Much of this finds its way to the bottom through the numerous deep cracks which are opened in the ice by the slow move- ment of the glacier. Thus glaciers rapidly wear away the rock surface over which they move, and carry for- ward an enormous quantity of rock waste. If the glacier descends into the sea, the rock waste which it carries is borne away by icebergs.
If the gla- cier does not reach the sea, the rock waste is deposited along its melting end, as an irregular sheet of sand, gravel, bowlders, and clay, called glacial drift , or as an irregu- lar range of hills, called a terminal moraine.
The Glacial Period. In north- ern Europe and in North America as far south as the Ohio and Missouri rivers, the surface of the land is cov- ered with glacial drift and the remains of terminal moraines. There are many rounded bowlders of a differ- ent kind of stone from any of the bed rock in the neighborhood, and many peculiar whaleback-shaped hills or drumlins , composed of glacial rock waste.
The bed rock of these re- It thus accumu- lates from year to year until it becomes so deep and heavy that the lower part is pressed into solid ice, and is forced to move slowly forward down the slope of the land. Such a thick sheet of slowly moving ice is a glacier. Bowlders deposited by an Old Valley Glacier in California. Some of these lakes occupy basins in the bed rock, but most of them occupy depressions in the irregular surface of the glacial drift, or old valleys across which a deposit of glacial drift forms a dam.
These peculiarities indicate that long ago there was a glacial penod of time, during which the northern hemisphere was colder than it is now. The American glacier moved out in all directions from the Laurentian Plateau p. The European glacier is called the Scandinavian glacier, because it moved out in all directions from the Scandinavian peninsula p.
These glaciers must have lasted thousands of years, but when the climate became warmer they melted away and left the glacial deposits spread over the countries which the ice had covered.
Where and how are glaciers formed? What work is done by them? What is an iceberg? Define glacial drift ; terminal moraine.
The surface of any sheet of water is thrown into waves by the wind. Light breezes cause mere rip- ples, but storm winds may heave the surface of deep water into billows as high as a three-story house. Waves raised by a storm in one part of the sea spread rapidly to a great distance, but even big waves do not affect the water to any great depth.
When a wave enters shallow water, its lower part drags on the bottom, while the upper part, rushing onward, falls forward, forming a breaker. Big waves drag on the bottom in deeper water than little waves, and hence may break farther from the land. At many places on the seacoast the water gradually rises for several hours and becomes many feet deeper; then for several hours it gradually falls to about its former level ; then it again slowly rises, and so on.
This slow and regular rise and fall of the sea is called the tide. The rise is flood tide, and the fall, ebb tide. As the earth rotates, these waves travel over the sur- face of the sea. When the crest of one of these waves reaches the coast, it is high tide at that place ; when the trough between the waves reaches the coast, it is low tide.
About twelve and a half hours intervene between one high tide and the next. Unlike wind waves, the tidal waves cause power- ful currents which extend to the very bottom of the sea. In the open sea the tidal wave is low and impercep- tible, but as it advances between the headlands of a coast, the approaching shores and the shallowing water force the wave to become much higher.
At the heads of some narrowing bays it is as much as 50 or 60 feet High and Rocky Coast, Maine. Work of Waves and Tides. Waves dash upon the coast at times with great force. If the shore is high and rocky, fragments of loosened rock are picked up and hurled against the cliffs, thus loosening other frag- ments, and undermining and rapidly cutting back the front of the cliffs; The fragments, pounded against the cliffs, or rolled backward and forward upon one another, are worn away, first to pebbles and then to fine sand.
Much of the sand made in this way on rocky head- lands is carried by tidal currents and by the wash of the waves into sheltered coves, or to straight stretches of low and gently sloping coast, where it is thrown upon the shore to form a smooth, sandy beach.
Thus the waves and tidal currents are constantly wear- ing back the rocky headlands, and building out the inter- vening coves — thus making the coast line more regular. In some places great storm waves breaking at some distance from the shore, and depositing sand in the water, gradually build up a long, low island, or barrier beach , parallel with the shore.
Between this beach and the mainland a lagoon of shallow water is inclosed. In other places, where opposing cur- rents leave still water between them, sediment from both Smooth and Sandy Beach, Maine. Coral Reefs and Islands.
Where the sea water is warm, clear, and not too deep, and where currents bring plenty of food, little animals called coral polyps live in great colonies attached to the sea bottom. When the animals die, their stony skeletons, composed of lime extracted from the water, remain, and to these skeletons other polyps of the same kind become attached.
Thus by the growth and death of countless polyps the rocky base on which they grew may gradually be built up to the surface of the sea, forming a low island, or coral reef. A coral island often has the form of a ring of land, sur- rounding a shallow lagoon; it is then called an atoll.
Define and explain waves ; breakers ; tides ; flood tide ; high tide ; ebb tide ; low tide; a bore ; a barrier beach ; a sandy hook ; a coral reef. In these layers of sediment the forms of the shells and bones are frequently preserved as fossils. The sandy deposits near the shore become layers of sand- stone ; the deposits of mud and clay become layers of shale or soapstone; and the oozes become different kinds of limestone and chalk, which are often little more than masses of fossils.
Great Barrier Coral Reef, Australia. What becomes of the Rock Waste. We have now learned that the weather and moving water and ice are con- stantly at work wearing away the land and carrying the rock waste down. In time, much of this rock waste reaches the sea, where it is deposited as sediment. The heavier material gravel and sand sinks soonest and forms a layer of coarse sediment near the shore, while the finer particles are carried farther out before they too sink and form a layer of mud or clay.
Nearly all the rock waste brought down to the sea is deposited within a few hundred miles of the coast, and with it are mixed the bones of animals washed from the land, or of sea animals. Farther from land almost all the deposits are the shells of sea animals. Of these there are millions ; and although most of them are very tiny, they make, in some regions, a thick layer of slime, or ooze , on the deep sea floor.
Continued additions make the deposits thicker each year, until the lower layers are pressed into By gradual upheaval these layers of hardened sediments on the sea bottom become land, and by the pressure and heat produced in the upheaval they may be hardened, crystallized, and changed still further — -lime- stone becoming marble; sandstone, quartzite; and shale, slate.
Some of the more deeply buried layers may even be melted and changed to granite or to lava. In this way have been formed nearly all the rocky layers of the land. Peat and Coal. In some places simple forms of plants grow thickly on the surface of fresh water near the shores of shallow ponds and lakes.
They may in time cover the entire surface of the water with a floating mat of vegetation, and this, growing on top but dying beneath, may eventually fill the lake with a dark mudlike mass called muck or peat, the whole forming a peat swamp, or bog. When thoroughly dried, peat may be used for fuel. Thousands of years ago great swamps, somewhat like the present peat bogs, but containing a vastly more lux- uriant vegetation, existed in many low- lands.
After their formation they were depressed below the sea and were covered by layers of mud and sand. The sediment grad- ually hardened to layers of rock, and the peat to beds of the black stonelike substance which we call coal.
In the later upheaval of these beds some of them were further changed into hard or anthracite coal. Petroleum and Natural Gas. Vegetable or animal matter which ages ago was deeply buried under sedi- ments, has sometimes been gradually changed, not into coal, but into rock oil , or petroleum, and into natural gas.
Both of these substances, like coal, make good fuel. They are obtained by boring deep wells through the overlying layers of rock. How does the ocean deposit near the shore differ from the deep sea deposit? Explain the formation of sandstone , shale ; lime- stone. Of peat ; coal. Of petroleum ; natural gas.

Hence the northern hemisphere must then be warmer than the southern, and we say the season of summer prevails in the northern hemisphere, but winter prevails in the southern hemisphere.
Six months later, in December, when the earth reaches the position C in the orbit, it will be seen that the north pole is then in the dark half, and the south pole in the lighted half of the earth. The southern hemisphere then receives the most heat, and has its summer while the northern hemisphere has winter. Each hemisphere is then cooler than in sum- mer, but warmer than in winter. It is then the season 1 9 of spring on one side of the equator, and the season of autumn , or fall ' on the other side.
Varying Lengths of Days and Nights. The points B and D in the orbit are called equinoxes equal nights ; for when, in September and March, the earth is at these points, the ends of the axis are on the line which divides the light half from the dark half of the earth, and rotation in this position produces days and nights of equal length all over the earth.
At all other points in the orbit the days and nights are unequal in length except on the equator , the inequal- ity being greatest in June and December, when the earth is at the points A and C called solstices.
At these times the days and nights are still equal in length on the equator, but unequal elsewhere, the inequality increas- ing rapidly as one advances from the equator toward either pole. Thus in the hemisphere having summer, the days are 14 hours long nights 10 in latitude 3 1 0 ; 1 6 hours long in lati- tude 49 0 ; 20 hours long in latitude 63 0 ; and on the parallel 23! Still nearer the pole continuous daylight lasts longer and longer, and at the pole it lasts for six months.
In the hemisphere having winter, the conditions are just reversed ; the nights are longer than the days, and near the pole the sun does not rise at all for weeks or months. Tropics and Polar Circles. When the earth is at B or D , the sun is directly vertically overhead at the equator, and its rays just reach both poles. Special names are given to the parallels reached by these rays of the sun at these times. The northern one is the Tropic of Cancer , and the southern, the Tropic of Capricorn.
Astronomical Zones. The torrid zone lies between the tropics. It is thus warmer, as a whole, than the other orB'X The earth, in addition to the rotation on its axis once every twenty-four hours, has another motion, called revolution , which carries it around the sun in a nearly circular path, or orbit.
The time re- quired by the earth to revolve completely around the sun is called a year. Inclination of the Axis. As the earth revolves, the axis always points in nearly the same direction toward the North Star, p. The axis is not per- pendicular to the orbit ; it leans, or inclines, about 23J 0 from the perpendic- ular, as shown in the diagram. March Half the zone is always in sunlight, and the days and nights are always of nearly equal length. No part of the year is either much warmer or much cooler than any other part.
Two frigid zones , one about either pole, are inclosed by the polar circles. These zones include all parts of the earth where, during the year, continuous daylight or continuous darkness lasts for 24 hours or more.
They are the coldest of the zones, for in summer the sun never rises high above the horizon, and during much of the winter it does not rise at all. A temperate zone lies between the torrid zone and each frigid zone. In the temperate zones there is a period of daylight and a period of darkness every 24 hours, but the noticeably long days in summer and long nights in winter cause warm summers and cold winters.
Explain the cause of the seasons ; of the varying length of days and nights. How are the astronomical zones determined and characterized? By means of a lamp and a globe or a ball, illustrate the position of the earth at the equinoxes; on June 21; on December Temperature Zones. The true heat belts, or tem- perature zones , are not fixed and regular like the astro- nomical zones.
They shift northward and southward with the changing seasons. Moreover, they have quite irregular boundaries. This is caused chiefly 1 by the irregular distribution of land and water over the earth, and 2 by the differences in elevation of the land.
When exposed to the suns heat, land becomes warm much quicker than water does ; and when warm it cools quicker than water. Hence in latitudes where the summers and winters are well marked, the land be- comes warmer in summer and colder in winter than the sea in the same latitude. The great body of air which surrounds the earth and extends upward to an unknown distance from its surface, is called the atmosphere. The upper part of the atmosphere, resting on the part beneath, compresses it and makes it denser.
Therefore the atmosphere is densest at the surface of the sea; but on high moun- tain tops it is so thin, or rare , that it is but slightly warmed by the sun in the daytime, while at night it per- mits the heat of the sun-warmed ground to escape. The air on the lowlands, however, is so dense that it is warmed by the sun in the daytime, and also helps to keep the ground warm at night.
It thus happens that the prevail- ing weather, or climate , of lowlands is warmer than that of highlands. Thus even near the equator, where snow is unknown in the lowlands, the tops of high mountains bear snow banks that are never entirely melted away.
But it must not be supposed that a person living on the top of a mountain would be always cold. Boundaries of the Heat Belts. The heat belts in July when they are farthest north and in January when they are farthest south are shown on the opposite maps. Each boundary line is an isotherm ; that is, a line passing through places having the same tempera- ture. In July, when the sun rises high over the northern hemisphere, and the summer days are long, the heat in the great land masses of North America and Eurasia is so great that the heat eqiiator line of greatest heat and the hot belt extend far north of the tropic.
It will be noticed also that at this season the heat equator lies but little north of the true equator over the cooler oceans, and that the temperate belt extends to the north pole. As July is in the winter of the southern hemisphere, the hot belt does not extend to the tropic in that hemi- sphere, nor the temperate belt to the polar circle. As the surface of the southern hemisphere is mostly water, the boundaries of its heat belts are comparatively regular.
Compare the January positions of the heat equator and the heat belts with their July positions. Explain the differences in position. In the lowest pair of maps the boundaries of the heat belts in both January and July are drawn, in order to show the temperature changes of each region during the whole year.
It thus appears that different parts of the earth have well-defined temperature conditions. Certain regions are always hot ; other parts have a temperate winter and a hot summer ; others again are always temperate. Some regions have a temperate summer and a cold winter ; some have a hot summer and a cold winter ; and in some the weather is always cold.
Define rare ; dense ; isotherm. How do the true heat belts differ from the astronomical zones, and why? Draw maps of the hemispheres, showing the tropics, polar circles, and true heat belts in July and in January. WINDS Cause of Winds. When air is heated, it expands and becomes lighter, bulk for bulk, than cooler air. This helps to explain why the smoke from a fire rises.
The heat expands the air over the fire and makes it lighter than an equal bulk of the cooler surrounding air. The cooler and heavier air, therefore, flows in below and pushes the lighter air up- ward, but is quick- ly warmed and is Illustrating Comparative Density of the Air. WINDS 21 ascending current is formed much like that over a fire.
The surface currents of cooler and heavier air are called winds. Thus over the fire there results an ascending cur- rent of air which carries the smoke upward. The rising current of warm air is fed below by currents of cooler air from the sides, while the ascending air gradually cools and spreads out above ; the general movement being as indicated in the diagram. When from any cause the air over a region becomes warmer than that over the surrounding regions, an Belts of Calms.
The north- east and southeast trade winds, when they meet, are forced slowly upward by the cooler and heavier air behind. The place of meeting is therefore marked by a narrow region of light, fiftul breezes or of calms, called the belt of equatorial calms. At the outer edge of the trade winds, in both the northern and the southern hemisphere, is a narrow belt of tropical calms in which the air is slowly settling down from the upper atmosphere.
Prevailing Westerly Winds. Beyond the tropical calms the gen- eral movement of the atmosphere is toward the poles — from the south- west in the northern hemisphere, and from the northwest in the southern hemisphere.
The winds of these regions, though most frequently from a westerly quarter, are unlike the trade winds in being exceedingly variable in direction.
They frequently form into vast whirls, which are called cyclones , in the center of which the air is rising. Cyclones are often hundreds of miles in diameter. They move eastward with the general drift of the atmosphere, often for great distances, before dying out.
Nearly all the ordinary storms in the temperate zones are cyclones. Trade Winds. Near the heat equator the air is always warmer and lighter than the air nearer the poles; hence there are nearly constant winds blowing toward the heat equator from some distance on both sides.
These winds are called trade winds. They are gentle winds, which over the level surface of the open ocean blow steadily throughout the year in nearly the same direction. Over the uneven surface of the land they are not so steady. Because of the rotation of the earth, moving air turns out of a straight course as it advances, turning to the right north of the equator, but to the left south of the equator. The trade winds, therefore, approach the heat equator from the northeast in the northern hemisphere, and from the southeast in the southern.
In the belt of prevailing westerly winds the land is warmer or cooler than the sea, according to the season. Hence these winds reach the west coasts of the continents as warm winds in winter, but as cool winds in summer.
For this reason the west coasts of North America and Eurasia in this belt have warmer winters and cooler summers than the east coasts. And Mirek is in the background at least, until the fourth minute! Nice guitar'n'drums chase in that fourth minute solo. What a voice! This may be the heir apparent to Marco Gluhmann.
He's got some growing to do but he has the pathos! I love the shift at into a different time signature with bass and guitar holding steady while Qba's drums and the lead guitar fly with multiple tracks given to display Mirek's frenetic flourishes.
I'm not sure I can take much more of this adrenaline pumping! Bass harmonics and toms support heavily distorted guitar arpeggi before Mirek sets up the song with a riff in the lead. The vocal here feels a little buried in the music.
Great drum, bass, and atmosphere here but the vocal is just not fitting. It's finally starting to work with the gorgeous violin-aided chorus--which is then followed by one of Mirek's signature ear candy leads. In the sixth minute organ and synth join as the drums double time for a spell, then things slow back down for another spell-binding violin solo.
What a gorgeous melody. Another song I'm going to want to hear a lot of. The pattern of heavy-Mirek riffing onslaught bridging the softer vocal sections is established until when a slow arpeggiation of a guitar chord progression plays with synth and electric guitar sounds flitting in from behind. Chords of orchestral synth wash join in with more toms while Satomi delivers a brief solo.
This is such gorgeous music. I am SO glad I decided to return and become one of those investors once I found out how to secure it. I cannot repeat enough how emotional this music is, masterful in both composition and delivery. This is NOT the album I was expecting: Believe albums always seem to fall short of expectations and desires.
Not this one. This is a sheer masterpiece of progressive rock music--one for the ages! Five stars; a certifiable masterpiece of progressive rock music. Review by Tarcisio Moura Prog Reviewer. At first I did not enjoy the album very much, it reminded me too much in the style of The Bread is Mine, but like another reviewer here said, after a few spins you start to get it: the music is very good, deceptively simplistic and full of details.
It is a step forward into the right direction, with better songwriting and more personality. Great prog stuff, even if not exactly bombastic.

In the 90s, you could hear house music that was popular on the airwaves but was still respected in the club. The key is to have a bridge between what is popular but with a clear deep house sound.
