Answer:

Mechanical weathering:

It is the physical breakdown of rocks and minerals into smaller fragments without changing their chemical composition.

It occurs due to external forces such as freeze-thaw cycles, abrasion, and plant roots expanding.

Chemical weathering:

It is the alteration of rock or mineral material into new compounds as a result of chemical reactions with water, air, and acids.

It occurs due to the reaction of minerals with water, carbon dioxide, oxygen, and other agents to form new compounds such as oxides, hydroxides, and carbonates.

Both:

Both processes work together to break down and transform the earth's crust.

Both processes are essential for soil formation and the creation of new landscapes over geological time scales.
