Geologists.
Scientists study seismic waves from earthquakes to learn about the layers of the Earth. By examining how these waves travel through the Earth, scientists can infer information about the composition and structure of the various layers beneath the surface.

Martian meteorites arrive on Earth through the impact of large asteroids or comets on the surface of Mars. These impacts can eject rocks and debris from Mars' surface, some of which eventually make their way to Earth as meteorites. Scientists can study these Martian meteorites to learn more about conditions on Mars and its history.
Scientists learn about the Earth's interior through the use of seismographs. Since seismic waves travel at various speeds when passing through different types of material, scientists will be able to formulate the conditions of the Earth's interior.
scientists use seismic waves to map earths interior by seismographs that measure the times at witch seismic waves arrive at different distances from an earth quake.

If we knew that the scientists wouldn't still have to learn it now would they? (if this is for the stupid earth's systems class that's the answer I put)

Scientists have studied seismic waves produced by earthquakes to learn about Earth's interior. These waves travel through the Earth at different speeds and can reveal information about the composition and structure of the planet's layers. By analyzing how seismic waves behave as they move through the Earth, scientists have been able to create models of the Earth's interior.
