Runoff and Erosion

the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited.

• weathering

• erosion

• deposition

• compaction

water, wind, gravity, waves, sand

• agents of erosion

• agents of the rock cycle

• agents of water cycle

• agents of plate tectonics

which is NOT an example of erosion

• rainfall and surface runoff

• rivers and streams

• coastal erosion

• ice wedging

How do plants prevent erosion?

• plant roots hold sediment in place, helping to stabilize the areas where they are planted.

• plants reduce runoff erosion

• both of these

• none of these

How do plant roots prevent soil erosion?

• tiny hairs found on plant roots play a pivotal role in helping reduce soil erosion,

• they keep the soil strong and binded to the land

• root systems help reduce erosion by holding soil in place.

• all of these

Erosion example: particles of soil piled up from puddles of rainwater

• True

• False
