The geologic process by which eroded sediments settle and are deposited or dropped in a new location.

• weathering

• erosion

• deposition

Which of the following creates or constructs deltas, alluvial fans, beaches, sand dunes or moraines?

• weathering

• erosion

• deposition

Which of the following is the destructive force that responsible for mass movement like landslides, mudflow, creep, and slump?

• weathering

• erosion

• deposition

Mechanical weathering where plant root systems break apart rock.

• root wedging

• frost wedging

• abrasion

• oxidation

Water is able to seep into the tiny cracks of many rocks. When the temperature drops, this water freezes and expands which then breaks the rocks apart. What kind of mechanical weathering is this?

• root wedging

• frost wedging

• oxidation

• mass movement
