Weathering, Erosion, and Deposition

What is physical weathering?

• The process of moving rocks and minerals from one location to another

• The process of creating new rocks and minerals from existing ones

• The process of changing the chemical composition of rocks and minerals

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

What is chemical weathering?

• The process by which rocks and minerals are broken down by chemical reactions.

• The process by which rocks and minerals are broken down by erosion.

• The process by which rocks and minerals are formed by heat and pressure.

• The process by which rocks and minerals are broken down by physical force.

Name one agent of erosion.

• Water

• Plants

• Wind

• Sunlight

How does weathering affect rocks?

• It turns rocks into gold

• It has no effect on rocks

• It causes physical and chemical changes to the rocks.

• It makes rocks stronger

What is the process of erosion?

• The process of building up rock, soil, and other materials by wind, water, or ice.

• The movement of rock, soil, and other materials by wind, water, or ice.

• The process of erosion is caused by the heat of the sun.

• The movement of rock, soil, and other materials by plants and animals.

What is deposition?

• The process of moving sediments, soil, and rocks from one place to another.

• The process of breaking down rocks into smaller pieces.

• The process in which sediments, soil, and rocks are added to a landform or landmass.

• The process of removing sediments, soil, and rocks from a landform or landmass.

Name one type of physical weathering.

• Chemical weathering

• Wind erosion

• Volcanic eruption

• Frost wedging

Name one type of chemical weathering.

• Freezing

• Condensation

• Sublimation

• Hydration

How does water contribute to weathering?

• Water strengthens rocks and minerals

• Water breaks down rocks and minerals through processes like hydration, hydrolysis, and dissolution.

• Water freezes rocks and minerals

• Water has no impact on weathering

How does wind contribute to erosion?

• Wind causes the ground to become more compact, preventing erosion

• Wind has no impact on erosion

• Wind creates a protective barrier around soil, preventing erosion

• Wind picks up and carries loose particles of soil and rock, causing abrasion.
