How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.
• makes the rocks last longer.
• expands cracks and breaks rocks.
• causes rocks to fall in landslides.

The process that breaks down rocks and other materials on Earth's surface is called

• Weathering
• Erosion

What is the process that picks up and moves weathered rocks?

• Erosion

• Weathering

How do plants weather rocks?

• Plants don't weather rocks.
• When roots grow into cracks of rocks and expand the rock breaks.
• When the plant moves water from the roots to the leaves, the rock breaks.

The two main types of weathering are:

• mechanical and physical

• potential and kinetic

• chemical and physical

• potential and chemical

_____________ is the dropping off/ depositing of rocks.

• Metamorphosis

• Deposition

• Weathering

• Erosion

Flood water pounding against a canyon wall and wearing it down

• Weathering
• Erosion
• Deposition

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

• Chemical weathering

• Mechanical weathering

• Erosion

• Deposition

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

• Frost wedging

• Exfoliation

• Oxidation

• Abrasion

What is the difference between weathering and erosion?

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

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

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

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