Earth 4.3

The diagram below shows granite bedrock with cracks. Water has seeped into the cracks and frozen. The arrows represent the directions in which the cracks have widened due to weathering.

Which statement best describes the physical weathering shown by the diagram?

• This type of weathering occurs only in bedrock composed of granite

• Enlargement of cracks occur because water expands and freeze.

• This type of weathering is common in regions of primarily warm and humid climates.
