The process by which rocks are broken down chemically or physically is known as:

• Weathering
• Erosion
• Deposition
• Transportation

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

• keeps the rocks in place.

• makes the rocks last longer.

• expands cracks and breaks rocks.

• causes rocks to fall in landslides.
