Wind, rain, ice, plant roots, and animal activities cause

• earthquakes

• Weathering

acid rain, rust, and chemicals from plants and animals cause

• chemical weathering
• physical weathering
• tsunamis
• deltas and sand dunes

Chemical and physical weathering are the same because they both

• build up landforms
• change the rock
• cause hurricanes and tornados
• break down rock

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.
