Question

A group of students on a field trip found loose rock and gravel at the foot of a rocky cliff. These rocks were of the same material as the rocks on the cliff. The students know that the place has a cold and wet climate. On the basis of this evidence, what could be a possible explanation for the presence of the loose rock and gravel at the foot of the cliff?

A) The rocks might have broken off due to alternating cycles of freezing and thawing of water.
B) Acid rain could have caused chemical weathering, resulting in the breaking of chunks of rock.
C) Oxygen in the air could have reacted with the minerals in the rock, causing the rusting of the rocks.
D) The rocks were probably always there. Weathering cannot be the cause, because it possible only in warm and wet conditions.
