Question

1. how does climate affect chemical and mechanical weathering?

a. mechanical weathering occurs more rapidly in warm, wet climates, and chemical weathering occurs more rapidly in cold climates
b. chemical weathering occurs more rapidly in warm, wet climates, and mechanical weathering occurs more rapidly in cold climates
c. chemical weathering occurs more rapidly in dry climates and mechanical weathering occurs more in windy climates
d. chemical and mechanical weathering occur more rapidly in warm, wet climates.

1. in which horizon of a soil profile is the parent material usually found?

a. a - horizon a
b. b - horizon
c. c - horizon c
d. o - horizon

1. when materials containing iron are exposed to water and oxygen, __________ can occur.

a. mechanical weathering
b. wedging
c. ironization
d. oxidation

1. what type of weathering is shown in the figure?

Explanation:

Question 8

Chemical weathering is enhanced in warm, wet climates due to increased chemical - reaction rates. Mechanical weathering is more prevalent in cold climates where processes like freeze - thaw action occur.

Question 9

The parent material in a soil profile is usually found in the C - horizon. The A - horizon is topsoil, the B - horizon is the subsoil, and the O - horizon is organic matter on the surface.

Question 10

When materials containing iron are exposed to water and oxygen, oxidation (rusting) occurs. Mechanical weathering is physical breakdown, welding is a joining process, and ironization is not the correct term for this reaction.

Answer:

1. B. Chemical weathering occurs more rapidly in warm, wet climates, and mechanical weathering occurs more rapidly in cold climates
2. C. C - horizon C
3. D. oxidation
