Question

Where can you infer that there may have been a mass extinction?

options:

There may have been a mass extinction at the time between the fourth and fifth rock layers.


There may have been a mass extinction at the time between the last two rock layers.


There may have been a mass extinction at the time between the first and second rock layers.


There may have been a mass extinction at the time between the third and fourth rock layers.

Answer 1

n the absence of specific information about the rock layers, it's challenging to make a precise determination. However, based on general principles of stratigraphy and the ordering of rock layers, the option that typically suggests a mass extinction event is:

"There may have been a mass extinction at the time between the fourth and fifth rock layers."

Mass extinctions often leave distinct markers in the geologic record, and the boundary between different rock layers can serve as an indicator of significant events in Earth's history, including mass extinctions. The transition between rock layers is known as a stratigraphic boundary, and certain layers, such as the boundary between the fourth and fifth rock layers, may correspond to periods associated with mass extinctions in the fossil record.
