Answer: A and E
Explanation: I did the USA testprep
The correct answer is D. ocean floor mapping and earthquake tracking
Tracking earthquakes is helpful because it shows where it came from and what caused it, as well as how it affected the environment, while ocean floor mapping is useful because it shows how the bottom of the sea changed over time which happens due to tectonic activity.
Because the time span of Earth's past is so great, geologists use the geologic time scale to show Earth's history.
