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 are events where a large number of species go extinct. Fossils of organisms that no longer live indicate that these species have disappeared from the Earth, which is evidence of mass extinctions. The other options are related to different aspects of paleontology like climate - change information from fossils, evolution (organisms changing over time), and continental drift (same - species fossils on distant continents), but not directly to mass extinctions.

Answer:

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