This type of weathering occurs when rock is physically broken down into smaller pieces of rock.
A
mechanical weathering
B
chemical weathering
C
erosion weathering
D
deposition
Explanation: 

Detailed explanation-1: -Mechanical Weathering Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock.

Detailed explanation-2: -Mechanical weathering-occurs when physical forces break rock into smaller and smaller pieces without changing the rock’s mineral composition.

Detailed explanation-3: -Mechanical weathering physically breaks bedrock into smaller pieces. The usual agents of mechanical weathering are pressure, temperature, freezing/thawing cycle of water, plant or animal activity, and salt evaporation.

Detailed explanation-4: -Physical weathering, also called mechanical weathering, is a process that causes the disintegration of rocks, mineral, and soils without chemical change. The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size).

Detailed explanation-5: -Mechanical weathering is also known as physical weathering. In this type of weathering, a large rock is disintegrated into smaller pieces of rocks. When rocks disintegrate or break up without experiencing any change in their chemical composition, it is known as mechanical weathering.
