Forces and Earth Processes Quiz

Which of the following is an example of a contact force?

• Gravitational force

• Magnetic force

• Frictional force

• Electrostatic force

How does water contribute to the process of erosion?

• By dissolving rocks

• By carrying away soil and rock particles

• By freezing and expanding

• By forming new minerals

Which of the following best describes deposition in rivers?

• The breaking down of rocks into smaller pieces

• The movement of sediment from one place to another

• The settling of sediment in a new location

• The chemical alteration of minerals

How does gravity affect the process of erosion?

• It causes rocks to dissolve in water

• It pulls sediment downhill

• It creates new landforms

• It changes the chemical composition of rocks

Explain how frictional force is different from gravitational force.

• Frictional force acts at a distance, while gravitational force requires contact.

• Frictional force requires contact, while gravitational force acts at a distance.

• Both forces require contact to act.

• Both forces act at a distance.

Analyze how the speed of a river affects the deposition of sediment.

• Faster rivers deposit more sediment.

• Slower rivers deposit less sediment.

• Faster rivers deposit less sediment.

• River speed does not affect sediment deposition.

Predict the impact of increased rainfall on the rate of erosion in a hilly area.

• Erosion rate will decrease.

• Erosion rate will remain the same.

• Erosion rate will increase.

• Erosion rate will stop completely.

Evaluate the role of gravity in the formation of landslides.

• Gravity prevents landslides by holding soil in place.

• Gravity causes landslides by pulling soil and rock downhill.

• Gravity has no effect on landslides.

• Gravity only affects landslides in flat areas.

Which type of force is responsible for the attraction between two magnets?

• Gravitational force

• Frictional force

• Magnetic force

• Electrostatic force

Identify the process that involves the breakdown of rocks.

• Breaking

• Deposition

• Weathering

• Erosion
