Question

1. which process is responsible for the recycling of earths crust?

a. transform faulting
b. seafloor spreading
c. subduction
d. mountain building

1. which process describes the action of wind - blown particles causing rock erosion?

a. chemical dissolution
b. aeolian weathering
c. frost wedging
d. hydrolysis

1. how does water velocity affect chemical weathering?

a. it slows down the dissolution of minerals
b. it has no effect on chemical weathering
c. it increases mineral precipitation
d. it accelerates the transport of dissolved minerals

1. what percentage does water expand when it freezes in rock cracks?

a. 5%
b. 7%
c. 9%
d. 11%

Explanation:

1. Subduction is the process where one tectonic plate is forced beneath another, recycling Earth's crust.
2. Aeolian weathering involves the action of wind - blown particles causing rock erosion.
3. Higher water velocity accelerates the transport of dissolved minerals during chemical weathering.
4. Water expands by about 9% when it freezes in rock cracks.

Answer:

1. c. Subduction
2. b. Aeolian weathering
3. d. It accelerates the transport of dissolved minerals
4. c. 9%
