Answer the following

Define erosion.

Erosion is the process by which natural forces like water, wind, ice, and waves wear away rocks and soil from the earth’s surface, and then transport these materials to new locations.

 

What is a plunge pool?

A plunge pool is a deep, round pool found at the base of a waterfall. It is formed by the powerful force of falling water which digs into the riverbed below the waterfall.

 

How are Ox – bow lakes formed?

Ox-bow lakes are formed when a river creates a large bend called a meander. Over time, the bend becomes tighter and eventually gets cut off from the main river, leaving a curved, isolated lake.

 

Name the major landforms formed by glacial erosion.

Major landforms formed by glacial erosion include cirques (bowl-shaped basins), arêtes (sharp ridges), U-shaped valleys, and horns (sharp mountain peaks).

 

Give a note on Mushroom rocks.

Mushroom rocks are unique rock formations found in deserts. They have a narrow base and a wider top, resembling a mushroom. They form because wind erosion wears away the lower part of the rock more than the upper part.

 

What is a lagoon? Give an example.

A lagoon is a shallow body of water separated from the sea by a barrier such as a sandbar or coral reef. An example of a lagoon is Chilika Lake in Odisha, India.
