Question

images a and b show how wind can change surface features. which conclusion is best supported by image a and image b? a. erosion is a destructive force, and image a and b are examples of erosion being a destructive force to land forms. b. when wind carries sand and there is a lack of moisture, erosion occurs as a constructive force that creates surface features like those seen in image a and image b. c. in image b, the lack of vegetation has caused erosion on the rock formation from the sand carried by the wind, but in image a the vegetation stopped the erosion from being a destructive force on the sand dunes. d. in image a, the vegetation helps hold the sand in place after it is carried by the wind making erosion a constructive force, but the sand is not held in place in image b where erosion is a destructive force creating the rock formation.

Explanation:

• Analyze Option A: Image A shows sand dunes (constructive, as dunes are built) and Image B shows rock erosion (destructive). So A is incorrect as it claims both are destructive.
• Analyze Option B: Wind erosion is typically destructive (wears down landforms) or constructive (builds, like dunes). But Image B’s rock formation is eroded (destructive), so B’s “constructive for both” is wrong.
• Analyze Option C: Image B has no vegetation, so wind - carried sand erodes the rock (destructive). Image A has vegetation that stabilizes sand dunes (stops erosion from destroying dunes, as dunes are constructive here). This matches the processes.
• Analyze Option D: Image A’s vegetation holds sand (erosion here is constructive for dunes), but Image B’s rock formation is eroded (destructive), but the description of “erosion as destructive creating the rock formation” is off (erosion modifies, not “creates” the rock formation in a destructive way to form it; it’s wearing down the existing rock). So D is incorrect.

Answer:

C. In image B, the lack of vegetation has caused erosion on the rock formation from the sand carried by the wind, but in image A the vegetation stopped the erosion from being a destructive force on the sand dunes.
