Exposure of rock to the changes of temperature is the cause of ________

A. Biological weathering

B. Chemical weathering

C. Degradational weathering

D. Mechanical weathering

Answer: Option D

Solution(By Examveda Team)

Exposure of rock to the changes of temperature is the cause of Mechanical weathering. Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens.
