Belle's 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 rock had cracks in them. she also found quite a few rocks that had split into pieces. what most likely caused the rocks in the region to weather?

a. snowfall
b. frost wedging
c. landslides
d. heavy rains

The most appropriate answer would be B. Frost wedging.

Frost wedging is a type of physical weathering of the rocks due to repeated cycles of the freezing and thawing of the water present in the crevices of the rocks.

Water has property that it expands upon freezing. This property of water helps in this type of rock weathering.

Water accumulated in the crevices of the rocks expands upon freezing and push the cracks further apart. With repeated cycles over time, it can even lead to the breaking of rocks into pieces.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
