What is mechanical weathering?

• It breaks rocks into smaller pieces without chemical change.

• It alters the chemical structure of minerals.

• It involves the movement of sediment.

• It is the process of forming new rocks.

Which of the following is an example of chemical weathering?

• Freeze-thaw cycles

• Wind abrasion

• Acid rain dissolving limestone

• Root wedging

(a)   are agents of erosion.

• Water, wind, ice, and gravity
• Sunlight and temperature
• Animals and plants
• Rocks and minerals

What happens during the process of deposition?

• Rocks are broken into smaller pieces.

• Sediment is deposited as the energy of transport agents decreases.

• Minerals are dissolved in water.

• Plants grow in cracks of rocks.

What is sorting of sediments?

• Larger particles settle first, while smaller particles travel further.

• Smaller particles settle first, while larger particles travel further.

• All particles settle at the same rate.

• Particles are sorted by color.

Match the following geological processes with their descriptions.

• Creation of elevated landforms due to tectonic activity.

• Mountain Formation

• Deposition of sediment from rivers where water slows as it enters a larger body of water.

• Delta Formation

• Formation of landforms along the coast due to wave action.

• Erosion

• Wearing away of the earth's surface by wind, water, or ice.

• Coastal Landform

Which of the following is an example of a coastal landform?

• The Andes Mountains

• The Grand Canyon

• Barrier islands

• The Mississippi Delta

What is a sand dune?

• A type of mountain

• A hill or ridge of sand piled up by wind or water

• A deep canyon

• A type of delta

How are canyons primarily formed?

• By volcanic activity

• By river erosion over millions of years

• By tectonic activity

• By wind erosion
