The Dynamic Earth

The breaking down of rocks and other materials on the Earth's surface.

• Erosion

• Deposition

• Exfoliation

• Weathering

The process by which rock and soil are moved from one place to another is called-

• Erosion

• Deposition

• Chemical weathering

• Mechanical weathering

This type of weathering in which rock is physically broken into smaller pieces.

• Deposition

• Mechanical weathering

• Erosion

• Chemical weathering

What do we call the process in which rock is broken down by changes in its chemical makeup.

• Deposition

• Erosion

• Chemical weathering

• Mechanical weathering

The grinding/scratching away of rock by other rock particles carried in water, ice, or wind

• Frost wedging

• Oxidation

• Abrasion

• Exfoliation

Plants/animals digging under ground with roots or claws to break apart rocks.

• 
  Burrowing

• Frost wedging

• Abrasion

• 
  Exfoliation

The breaking off of the curved sheets or slabs from a rock's surface due to drastic changing temperatures.

• Frost wedging

• 
  Abrasion

• Exfoliation

• Burrowing

A type of chemical weathering in which a substance combines with oxygen, as when iron oxidizes, forming rust.

• Acid rain

• 
  Reaction to water

• 
  Oxidation

• Exfoliation

The image above depicts the effects of chemical weathering breaking down limestone. Which type of chemical weathering causes this reaction?

• Acid rain

• Exfoliation

• Oxidation

• Abrasion

What is the difference between weathering and erosion?

• 
  Erosion breaks down the rocks, and weathering carries the broken pieces away.

• Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.

• Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

• 
  Weathering breaks down rocks, and erosion carries the broken pieces away.
