    The earth gains heat from the sun—cold by its absence. Air and water expand by warmth, and contract by cold. The sun is therefore the cause of expansion and contraction. The air and water are warmed on the centre of the earth—the equator. They are cooled at its extremities—the Poles. As they contract by the cold, they are supplied by the warm. As they cool, they return to warmth. There is therefore a constant circulation. Circulation of air and water produces force. Force acts on dusts. Dust is moved on dry land and in the water. Water and air occupy the place of the dusts they move. These movements cause subtractions on the surface and on the water bed. Both are therefore lowered in places. The surface of the water is therefore always sinking. Dust is therefore left dry and high. Mountains are caused by the sinking of waters. The sinking of waters is due to the sun. Mountains are therefore due to the sun. The sun gives heat.
