What type of weathering is pictured?

• mechanical weathering

• chemical weathering

What is physical weathering?

• The breakdown of rocks through chemical changes.

• The process by which rocks are broken down by physical factors like wind and water.

• The transportation of sediment by erosion.

• The change in phase of water within rocks.

Answer explanation

Physical weathering is the process of rocks being broken down by physical factors like wind and water.

While hiking with his friends, David noticed that the rocks along the trail were slowly breaking apart due to the constant wind and water flow. What is this process called?

• The breakdown of rocks through chemical changes.

• The process by which rocks are broken down by physical factors like wind and water.

• The transportation of sediment by erosion.

• The change in phase of water within rocks.

Answer explanation

Physical weathering is the process of rocks being broken down by physical factors like wind and water.

How does the presence of soil affect weathering?

• Soil protects rocks from weathering

• Soil has no effect on weathering

• Soil can accelerate weathering by retaining moisture

• Soil decreases chemical weathering

The diagrams shows a rock with water trapped in the cracks during the day and at night.
