Erosion

What is erosion?

• The process of breaking a rock into smaller particles by altering the chemical structure of the minerals in the rock.

• The overall process that results in movement of rocks and soil from one place on Earth’s surface to another.

• The process of breaking a rock into smaller pieces by physical means.

• The process of depositing sediments in low-lying regions called sedimentary basins.

When does deposition occur?

• When rock is broken into smaller pieces by physical means.

• When sediments accumulate in low-lying regions called sedimentary basins.

• When the speed of the medium transporting the sediments diminishes.

• When sediments are compressed and uplifted to form mountains.

Where do sediments accumulate?

• In sedimentary basins.

• In low-lying regions called sedimentary basins.

• On the ocean floor near tectonic plate boundaries.

• In high mountains.

What happens when tectonic plates collide near a sedimentary basin?

• Sediments are compressed and uplifted to form mountains.

• Sediments accumulate in low-lying areas.

• Sediments are forced upward as the ocean crust is subducted beneath them.

• Sediments are transported by rivers into lakes and ultimately end up in the ocean.
