Which term refers to the amount of space exposed on the outside of an object?

• surface area

• water

• abrasion

• oxidation

Why will weathering occur more quickly to a rock that has been broken into several pieces?

• The surface area of the broken pieces is larger.

• The surface area of the broken pieces is smaller.

• The total weight of the rock decreases when it is broken.

• The total weight of the rock increases when it is broken.
