Question

Rock disintegration without any change in the chemical constituents of the rock:

पर्याय

• Block Disintegration

• Mechanical Weathering

• Carbonation

• Organic Weathering

Answer 1

Mechanical Weathering.

Explanation:

Mechanical weathering (also known as physical weathering) refers to the process where rocks are broken down into smaller pieces without changing their chemical composition. This disintegration occurs due to physical forces like temperature changes, freeze-thaw cycles, or pressure release. The chemical constituents of the rock remain unchanged in mechanical weathering, distinguishing it from chemical weathering, where chemical reactions alter the rock’s composition.
