Three River Channel Processes are– 1) Erosion ((The wearing away of the land)2) Transportation (The movement of eroded material)3) Deposition (The laying down of eroded material)

The action of running water which include streams, rivers, and rainfall, have constantly shape the surface of the surface of earth through erosion and depositional processes. River (or running water) is one of the most active agent of land form development.

5.1 THE THREE FUNCTIONS OF A RIVER Running water or a river affects the land in three different ways. These are known as the three functions of a river. They are (i) erosion (ii) transportation and (iii) deposition. Throughout its course a river displays all the three activities to some extent.

Rivers are an important energy source. During the early industrial era, mills, shops, and factories were built near fast-flowing rivers where water could be used to power machines. Today steep rivers are still used to power hydroelectric plants and their water turbines.

The force of the water is so powerful it can turn rotor blades like those on a wind turbine (the modern day windmill) with water instead of wind! This movement can produce enough energy to heat houses or power factories.

What is geological work of ocean?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.

What is geological work of wind?The movement of the atmosphere in a direction parallel to the earth surface is wind. Geological work of wind. The earth is surrounded by an envelop of gases called the atmosphere. The movement of the atmosphere in a direction parallel to the earth surface is wind.

Air is the invisible mixture of gases that surrounds the Earth. Air contains important substances, such as oxygen and nitrogen, that most species need to survive. Human beings, of course, are one of those species. Sometimes, the word “atmosphere” is used instead of the word “air.”

Geology. The beaches were formed by winds coming off Lake Michigan, which drop sand when the wind hits plants, dunes, and hills. As the lake level of Lake Michigan dropped at the end of the Ice Age, the shoreline receded, and new dunes were formed along the lakeshore.
