Valleys, Gorges, Canyon As we discussed above, valleys are formed as a result of running water. The rills which are formed by the overland flow of water later develop into gullies.

There are three major subdivisions of geology, physical geology, historical geology, and environmental geology.

The geological action of glaciers comprises erosion, transportation and deposition which together constitute what is known as glaciation. The geological action of glacier is mainly due to its flow.

Geological work of sea. Although a sea is a reservoir of water but by virtue of its enormous dimension and the consequent generation of waves. on its surface, it acts as active agent performing geological work in form of erosion and deposition of eroded material. in sea basin.

The number of molecules colliding with your face increases as the wind speed increases. The rate at which your face loses heat increases, and you cool down faster. The wind-chill accounts for the increased loss of heat by the movement of the air.

Air is constantly moving around the earth. This moving air is called wind. Winds are created when there are differences in air pressure from one area to another. In areas of high-pressure (sinking air), air at ground level spreads out, moving away from the high pressure.

Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.

Oases (plural of oasis) form when the wind cuts out deep channels in low-lying areas of the desert and uncovers underground water that fell as rain long ago. The water in some oases was rain that fell there about 20,000 years ago.

Streams provide many benefits to humans. Besides providing drinking water and irrigation for crops, streams wash away waste and can provide electricity through hydropower. People often use streams recreationally for activities such as swimming, fishing, and boating. Streams also provide important habitat for wildlife.
