Weathering, Erosion, deposition and mass movement

Root wedging is a type of

• Chemical weathering

• Mechanical weathering

• Mass movement

• Slump

Very slow movement of the ground

• Landslide

• Mudflow

• Rockslide

• Creep

Gravity plays an important role in this types of erosion

• Abrasion

• Exfoliation

• Mass movements

• Carbonation

Acid rain occurs in this type of weathering

• Carbonation

• Hydrolisis

• Living organisms

• Abrasion

Mass movement that contains 60% of water.

• Landslide

• Slump

• Mudslide

• Rockslide

Agents that cause weathering.

• CO2, O2, H2O, C2

• CO2, N2, O3

• O3 and H2O

• H2O, C2 and O3

Factors that affect the rate of weathering.

• Surface area and Exposure

• Agricultural practices

• Type of rock

• All are correct

Factors that cause erosion.

• Wind, living organisms, trees

• Water, wind, ice and gravity

• Water and gravity

• Living organisms

Difference between weathering and erosion.

• Weathering includes living organisms

• Erosion is just the breaking of the rocks.

• Erosion is the movement of the rocks and weathering just the breaking.

• Erosion does not happen in some regions.

Deposition

• Is the settling of the rocks.

• Changes the form of land in the planet

• Comes after erosion.

• All are correct.
