Question

1. frost wedging breaks rock apart because

a.rocks contract when they become very cold
b.chemical weathering is faster in cold weather
c.frost forms from water vapor by condensation
d.water expands when it freezes

1. what word is most closely related to the word weathering?

a. transportation
b. breakdown
c. gravity
d. rain

1. as a rock is broken apart by physical weathering processes...

a.its total surface area decreases
b.its total surface area increases
c.new minerals form in the rock material
d.the mass of the rock increases

Explanation:

1. Question 5: Frost wedging is a physical weathering process where water seeps into rock cracks, freezes, and expands, exerting pressure that breaks the rock apart.
2. Question 7: Weathering is the process of breaking down rocks, soils, and minerals at the Earth's surface, so the term most closely related is breakdown.
3. Question 9: When a rock is broken into smaller pieces by physical weathering, the total surface area of all the pieces combined is larger than the surface area of the original single rock. No new minerals form, and the total mass remains the same.

Answer:

1. D. Water expands when it freezes
2. B. Breakdown
3. B. Its total surface area increases
