slow changes to land

• Animals dug a large hole through the rock.
• Fire burned through the rock and made a hole.
• A plant's roots grew through the rock and broke it.
• Sand blew against the rock to change its shape.

When ocean waves crash against rocks, 

• the rocks will melt
• the rocks will explode as the waves hit them
• pieces of the rock may break off due to weathering
• the rocks will grow larger in size

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.
• makes the rocks last longer.
• expands to crack and break apart rocks.
• causes rocks to roll across the ground.
