This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over much shorter time frame than mechanical weathering.
• Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
• Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.
• Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.

Wind blowing sand from one location to another is called

• Weathering
• Erosion
• Deposition

Water getting into cracks, freezing, and breaking the rocks or pavement apart is called?

• Weathering
• Erosion
• Deposition

Waves dropping sand on the beach is called?

• Weathering
• Erosion
• Deposition

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.
