Weathering is the distintegration and decomposition of material of the earth’s crust by their exposure to atmosphere.
Define weathering.
Weathering is the process of the disintegration or decomposition of rocks at or near the Earth’s surface due to the action of natural agents like water, temperature changes, wind, and biological activity. It leads to the breakdown of rocks into smaller pieces or changes their chemical composition, without any removal of the material from the site.

Define the following term briefly:

Define the following term briefly:
Chernozems
Chernozems — are the richest soils found in the grassy steppes and are best for wheat cultivation.
Define Granular Disintegration.
Granular disintegration takes place in crystalline rocks where the grains of the rocks become loose and fall out. This is due to the action of temperature & frost.
Define: Moraine
- Landforms formed by the glacial deposits of valley or continental glaciers are termed as Moraines.
- They are of various shapes and sizes, like ground, terminal and lateral moraine, etc.
Define Esker.
Long Narrow ridges composed of boulders gravel and sand deposited by streams of melting water which run parallel to a glacier are called Eskers.
Define Drumlin.
Drumlins are deposits of glacial moraines that resemble giant inverted teaspoons or half cut eggs.
What is a wave cut platform?
- Flat surface found at the foot of sea cliffs are called wave platform
- Wave cut platform is also referred as beach, shelf, terrace and plain.
