Question

which two of the options below are the best examples of how tectonic plate movement changes earths surface? (3points) a continents on earth are far apart but used to be connected. b the grand canyons walls continue to erode. c a new ocean floor forms in the mid - atlantic ridge. d land builds up along a bend in a river from deposition

Explanation:

To determine the best examples of tectonic plate movement changing Earth's surface, we analyze each option:

• Option A: Continental drift (due to tectonic plates) caused continents to separate from a supercontinent (e.g., Pangaea), showing how plate movement changed Earth’s surface.
• Option B: Grand Canyon erosion is due to water (river) erosion, not tectonic plates.
• Option C: Mid - Atlantic Ridge is a divergent plate boundary where new ocean floor forms as plates move apart, a direct result of tectonic plate movement.
• Option D: River deposition (land build - up along river bends) is a result of water - related sedimentation, not tectonic plates.

So the two best examples are A and C as they are directly related to tectonic plate movement.

Answer:

A. Continents on Earth are far apart but used to be connected, C. A new ocean floor forms in the Mid - Atlantic Ridge
