Question

which evidence suggests that several mass extinctions have occurred during earths history?
fossils provide information about water level and temperature.
many fossils demonstrate that organisms have changed over time.
fossils of the same species have been found on distant continents.
many fossils of organisms that are no longer living have been discovered.

Explanation:

Mass extinctions involve large - scale loss of species. Fossils of extinct organisms (no longer living) indicate that such events occurred. Option A about water level and temperature from fossils doesn't directly relate to mass extinctions. Option B (organisms changing over time) is about evolution, not mass extinction. Option C (same species on distant continents) is related to continental drift, not mass extinction.

Answer:

D. Many fossils of organisms that are no longer living have been discovered.
