Which sources do scientists use to study the interior of earth? check all that apply. earth’s orbit - core samples - sea level - earthquakes - s waves - rock composition

Core samples, earthquakes, S waves and rock composition are the sources do scientists use to study the interior of Earth.

The samples of core layer of the earth tells us about interior parts of the earth because the core is present inside the earth so the samples of core provides information about the interior of earth. The composition of rock that comes from the interior of earth due to volcanic eruption that also provides information about earth.

Scientists are able to understand Earth's interior by studying seismic waves because these waves travels through the earth interior materials so we can say that Core samples, earthquakes, S waves and rock compositions helps scientists to study the interior part of Earth.
