Question

fossils of an aquatic organism are found at the top of a mountain. how does this explain events in earth’s history?
a. this area was ideal for aquatic organisms to become land organisms, and then migrate to the mountain tops for food.
b. this area used to be under an ancient shallow sea before mountain building occurred.
c. this area was mountainous and once flooded due to extended periods of precipitation.
d. this area had several predators that would catch aquatic organisms, and then drag their prey to the top of the mountains to eat.

Explanation:

Fossils of aquatic organisms found on a mountain top suggest geological changes. Aquatic organisms live in water. Option B makes sense as mountain - building (orogeny) can lift areas that were once underwater (like a shallow sea) to form mountains. Option A is incorrect because there's no indication of aquatic - to - land transition and migration for food. Option C: extended precipitation would not create a long - term enough aquatic environment for fossil formation. Option D: predators dragging prey would not lead to fossil formation in such a way.

Answer:

B. This area used to be under an ancient shallow sea before mountain building occurred.
