Question

What would be the best reason for

finding a bunch of broken rocks

A. The pressure of the glacier crushed
them
B. Water seeped into the cracks and
expanded as it turned to ice
C. Modern day animals moved the
rocks around
D. Dinosaurs broke them.

Answer 1

B. Water seeped into the cracks and

expanded as it turned to ice

Step-by-step explanation:

This is because as the glacier melts, water seeps into cracks on the rock underneath the glacier. As this water seeps into the cracks, it would be turned into ice. As the ice expands, it causes the rock to break up into pieces.

This process is called mechanical weathering.
