Following are the factor responsible for erosional transportational and depositional work of a river:-

• Slope of land
• The type of rock
• Volume of water flowing in the river
• The length of flow
• Volume of sediments in the river

Depending on the location of the deposits, moraines can be divided into four type which are as follow:-

• Ground Moraines
• Lateral Moraines
• Medial Moraines
• Terminal Moranies

 The Jakobshavn Glacier in Greenland is one of the fastest moving glaciers in the world. It moves at the rate of 46m per day.

Glaciers move at different velocities daily ranging from 1 cm to 1 m. The Jakobshavn Glacier in Greenland is one of the fastest moving glaciers in the world. It moves at the rate of 46m per day.

The movement of air is called wind. Wind is a gaseous agent of erosion. The erosional, transportational and depositional work of wind is more prominent in deserts and semi-arid region.

Wind carries small sand particles, small pebbles, etc. along with it. These particles cause erosion along rocks coming in the way due to friction. This leads to formation of mushroom rocks, deflation hollows, yardangs, etc.

Afforestation is the process of planting trees on a large scale, which helps to stabilize the soil and prevent erosion.

Chernozems are known as the richest soils (3), Black soil is rich in calcium carbonate (1), Laterite contains aluminium compounds (2), Terra Rosa is formed in limestone (4), and Alluvial soil is a mixture of clay, sand, and silt (5).

Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing. This is the best method to reduce the soil erosion in the hilly areas.

Khadar, Bangar, and Bhabar are all types of alluvial soils classified by their age and location in river plains. Regur (Black soil) is formed from volcanic rock, making its formation process distinct.
