Define erosion.
Erosion is the wearing away of the landscape by different agents like water, wind, ice and sea waves
What is a plunge pool?
Plunge pool is a hollow feature at the base of a waterfall which is formed by cavitation.
Name the major landforms formed by glacial erosion.
Cirque and arête
Give a note on Mushroom rocks.
Rocks in the shape of a mushroom, are commonly called as mushroom rocks. Winds erode the lower section of the rock more than the upper part. Therefore, such rocks have narrower base and wider top.
What is a lagoon? Give an example.
Lagoon is a shallow stretch of water partially or completely separated from the sea. E.g. Chilka lake in Odisha, Pulicat lake in Tamil Nadu
Tributary and Distributary
Tributary: A stream or river that flows into and joins a main river.
Distributary: A stream that branches off and flows away from a main stream.
‘V’ shaped valley and ‘U’ shaped valley
The running water in the river erodes the landscape, which creates a steep-sided valley like the letter ‘V’ known as ‘V’ shaped valley.
U’ Shaped Valley is found beneath the glaciers which is deepened and widened by the lateral and vertical erosion.
The ends of the meander loops come closer and closer.
Due to continuous erosion and deposition along the sides of the meander, the ends of the meander loop comes closer and closer
