Question

Which one is not a natural force that causes weathering of rock? (a) 19. Wind (b) Water (c) Earthquake d glacier​

Answer 1

Explanation:

Physical or mechanical weathering is the disintegration of rock into smaller pieces. Physical weathering is often caused by atmospheric changes such as heat or freezing temperatures. Frost wedging results when water freezes and expands in crevices, causing rock to crack. Also, extreme temperature changes such as rapid heating and cooling can cause rock to expand and contract. Plants cause weathering when roots growing on or under rocks gradually break the rock apart. In addition, animals such as rodents, earthworms and insects often disrupt and break rock apart by burrowing and digging. Wind is another force that causes abrasive weathering by blowing sand against rock faces.
