Question

radioactive dating
which statement describes why scientists typically use radioactive dating of rocks in the earth’s crust?
it can allow scientists to determine how the climate has changed over the past million years.
it can help scientists calculate the number of earthquakes that occurred in an area.
it can give an approximate age of sediment layers found in the earth.
it can assist scientists with estimating the distance that continental plates move apart.

Explanation:

Radioactive dating is used to find the age of rocks and fossils. By measuring the decay of radioactive isotopes in rocks, scientists can determine how long ago the rock formed. This helps in finding the approximate age of sediment layers. Climate change is studied through different proxies like ice - cores, earthquake numbers are determined by seismological methods, and plate movement distances are measured using GPS and geological markers.

Answer:

It can give an approximate age of sediment layers found in the Earth.
