Answer Details
The process which causes exposed rock surface to break and crumble is known as "weathering". Weathering can be described as the breaking down of rocks, soils and minerals through direct contact with the Earth's atmosphere, water, and biological organisms. Weathering occurs due to mechanical, chemical or biological processes that cause rocks to disintegrate into smaller particles. Mechanical weathering is caused by physical processes such as temperature changes, pressure, and ice wedging, while chemical weathering is caused by chemical reactions that alter the mineral content of rocks. Biological weathering is caused by the activities of living organisms that break down rocks and minerals.
