Question

Where is the daily temperature change the most significant in rock weathering?

A) the humid tropics
B) mountain summits
C) the Arctic region
D) the subtropical deserts
E) midlatitude valleys

Answer 1

The most significant daily temperature change in rock weathering occurs in midlatitude valleys, where rocks experience hot daytime temperatures and much cooler nighttime temperatures.

Step-by-step explanation:

The most significant daily temperature change in rock weathering occurs in E) midlatitude valleys. Midlatitude valleys experience a wide range of temperatures throughout the day, with hot daytime temperatures and much cooler nighttime temperatures. These temperature fluctuations can cause rocks to expand and contract, leading to mechanical weathering.
