Weathering, Erosion, Deposition, Mass Wasting, and Glaciers

What is the mechanical and chemical processes that change objects on Earth's surface over time called?

• Weathering

• Erosion

• Deposition

• Soil

This type of weathering occurs whenever physical processes naturally break rocks into smaller pieces.

• Chemical Weathering

• Mechanical Weathering

This type of weathering is one of the most effective weathering processes. It involves water entering cracks in rocks, freezing, expanding, and widening cracks in rocks.

• Abrasion

• Plants

• Ice Wedging

• Animals

This type of weathering changes the materials that are part of a rock into new materials.

• Chemical Weathering

• Mechanical Weathering

What is considered to be the most important in chemical weathering due to most substances dissolving in it?

• Water

• Fire

• Mud

• Sand

This process causes chemical weathering whenever elements or molecules are combined with the element oxygen.

• Chemical Weathering

• Mechanical Weathering

• Oxidation

• Acids

This process is the removal of weathered material from one location to another.

• Erosion

• Deposition

• Mechanical Weathering

• Chemical Weathering

This is the laying down or settling of eroded material.

• Weathering

• Deposition

This process is the downhill movement of a large mass of rocks or soil because of the pull of gravity.

• Weathering

• Erosion

• Deposition

• Mass Wasting

This type of mass wasting is the rapid downhill movement of soil, loose rocks, and boulders.

• Earthquake

• Landslide

• Weathering
