Question

select the correct answer. belles grandfather lives in a region where the temperature drops below 0°f at night. when belle visited her grandfather, they hiked up a hill. belle noticed that a lot of rocks had cracks in them. she also found quite a few rocks that had split into pieces. what most likely caused the rocks in this region to weather? a. snowfall b. frost wedging c. landslides d. heavy rains

Explanation:

Frost wedging occurs when water seeps into cracks in rocks, freezes (since the temperature drops below 0°F at night), and expands, causing the rocks to crack further or split. Snowfall itself doesn't directly cause rock - weathering like frost wedging. Landslides are mass - movements of rock and soil and not a typical weathering process for individual rocks in this context. Heavy rains are not indicated as a factor here and are not as effective as frost wedging in cold regions for rock weathering.

Answer:

B. frost wedging
