Question

If no water is involved, rocks can mechanically weather if they undergo ________ temperature

change cycles.
A) a dozen
B) two
C) millions of
D) hundreds of
E) thousands of

Answer 1

Rocks undergo mechanical weathering through hundreds of temperature change cycles, leading to physical breakdown without chemical changes.

Step-by-step explanation:

Rocks can mechanically weather if they undergo hundreds of temperature change cycles. This type of weathering is a physical process in which the rock is broken down into smaller pieces without any change in its chemical composition. Temperature fluctuations lead to expansion and contraction of the rock material, causing it to crack and eventually break apart over time.
