Weathering, Erosion, and Deposition

What is chemical weathering?

• Chemical weathering is the process by which rocks and minerals are broken down and altered through volcanic eruptions.

• Chemical weathering is the process by which rocks and minerals are broken down and altered through biological activities.

• Chemical weathering is the process by which rocks and minerals are broken down and altered through physical forces such as wind and water.

• Chemical weathering is the process by which rocks and minerals are broken down and altered through chemical reactions with water, air, and other substances in the environment.

What is physical weathering?

• The process of breaking down rocks and minerals into larger pieces without changing their chemical composition.

• The process of breaking down rocks and minerals into smaller pieces by changing their chemical composition.

• The process of breaking down rocks and minerals into smaller pieces without changing their chemical composition.

• The process of changing the chemical composition of rocks and minerals without breaking them down.

What is wind erosion?

• The process by which wind removes and transports soil and sediment from one location to another.

• The process by which wind changes the temperature of the Earth's atmosphere.

• The process by which wind causes earthquakes and volcanic eruptions.

• The process by which wind adds and deposits soil and sediment in one location.

What is sediment deposition?

• The process by which sediments settle and accumulate on the Earth's surface or in bodies of water.

• The process by which sediments are transported from one location to another.

• The process by which sediments are transformed into rocks.

• The process by which sediments are eroded and removed from the Earth's surface or bodies of water.
