In deserts rocks in the shape of a mushroom, commonly called mushroom rocks.

Cirque, Aretes, U' Shaped Valley

Due to continuous erosion and deposition along the sides of the meander, the ends of the meander loop comes closer and closer. In due course of time the meander loop cuts off from the river and forms a cutoff lake, also called an Ox-bow lake.

Plunge pool is a hollow feature at the base of a waterfall which is formed by cavitation.

(i) Thenmning water in the river erodes the landscape, which creates a steep-sided valley like the letter 'V' known as 'V' shaped valley.
(ii) Falling of river water over a vertical step in the river bed is called waterfall. lt is formed when the soft rocks are removed by erosion. E.g. Coutrallam falls across the river Chittar in Tamil Nadu.
(iii) Plunge pool is a hollow feature at the base of a waterfall which is formed by cavitation. Alluuvial fan is a deposition of sediment occurs at which the river enters a plain or the foot-hills.
(iv) As the river enters the plain it twists and turns forming large bends known as Meanders. E.g. Meanders along the River Vellar near Sethiyathope in Cuddalore District, Tamil Nadu
(v) Due to continuous erosion and deposition along the sides of the meander, the ends of the meander loop comes closer and closer. In due course of time the meander loop cuts off from the river and forms a cutoff lake, also called an Ox-bow lake.

A large body of ice moving slowly down a slope or valley due to gravity is called a glacier.

The water flowing from its source to river mouth, along a definite course is called a River.

Weathering is the breaking and falling apart into small pieces of the rocks on the earth's surface

Gradation is the process of levelling of highlands through erosion and filling up of lowlands through deposition

The endogenic process (internal process) leads to the upliftment and sinking of the earth's surface at several places
