Which of the following statements does NOT illustrate the effects of human activity in creating erosion problems?

• Building roads can increase erosion due to the change in drainage patterns.

• Terracing along a mountainside can lead to erosion

• Building on steep slopes can lead to landslides.

• soil can be washed away from new construction sites due to clearing trees and brush

Soil is made of many things, including tiny particles of rock. Which is one way rocks are broken down into rock particles?

• Molecules of water that are superheated inside of rocks can build up pressure that breaks rocks into rock particles.

• Radiation from sunlight creates tons of tiny cracks in the rock, which expand until they break.

• Molecules of water that freeze inside rocks can expand and break rocks into rock particles.

• Oxygen from the atmosphere gets absorbed by the rock, which expands until it breaks.

Based on the diagram, structure X is

• a delta that is changing due to sediment deposits from ocean currents.

• an island that is changing due to the movement of plate boundaries.

• a delta that is changing due to sediment deposits from a river.

• an island that is changing due to increasing volcanic lava flow.
