Question

remy has learned that rock and soil from avalanches can cause tsunamis by falling into the ocean. remy wonders if the height of the mountain has anything to do with the eventual size of the tsunami wave. how should remy test this? a. build a model town at the edge of a pool and see how large waves must be to cause damage to the buildings. b. pour different amounts of sand down the side of a model mountain into a pool and see how large each resulting wave is. c. cause avalanches on several different mountains and see how large each resulting tsunami is. d. build different - sized model mountains at the edge of a pool, pour sand down the side of each mountain, and see how large each resulting wave is.

Explanation:

Remy wants to test the relationship between mountain - height and tsunami - wave size. Option D builds different - sized model mountains (varying height) and observes the resulting wave size, directly testing the hypothesis. Option A focuses on wave damage to buildings, not the relationship between mountain height and wave size. Option B varies the amount of sand, not mountain height. Option C is unethical and dangerous to cause real avalanches on mountains.

Answer:

D. Build different - sized model mountains at the edge of a pool, pour sand down the side of each mountain, and see how large each resulting wave is.
