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

The core samples

Explanation:

The scientist study the interior of the earth in indirect way. Because the interior temperature of the earth is so high that, no one can reach to it.

They collect samples of different layers, from the sea levels, and the earthquake prone areas to know the nature of the earth.

There are varieties of earth digging experiment is going on to know more about the earth. By collecting samples of digging material, scientist conclude that the different layers are having different compositions.

The cause of earthquake also provides proof, inside the earth, molten lava / magma are always in motion. They are in a motion of convection, where they move in circular way from top to bottom.

Sometime due to excess heat or thinner layer of some part of earth, or pressure disturbance, they expel out from the core.

These are coming out in two waves - P wave / primary wave. It cause more hazard to the earth surface. This P wave is followed by S wave which is less harmful effect.

After earthquake collecting this cool magma, scientist determine the nature of the interior of the earth.
