  1. I believe they send some sort of wave toward the center and see how it reflects.

  2. Scientists study earthquakes, when they pass through the earth they travel through different mediums which results in different speeds. They can also study volcanos.

  3. Scientists determine the composition of the earth by the size, mass, and moment of inertia of the planets.

  4. It’s like a wave of sound and certain type of rock or substance either slows it down or makes it speed up

  5. Measurements of surface chemical composition, either by direct sampling or through observations.

  6. Made up my solid materials and a ring like sound or slows down

  7. Scientists determine this by sampling pieces of the earth under the crust

  8. They determine the composition of the earth by its mass or size.

  9. They send seismic waves that determine the density of the different layers.

  10. They sample pieces of earths crust, and look at size and mass.

  11. They do this by sampling pieces of Earth (mass or size) , earthquakes, and seismic waves.

  12. They can study the inside of volcanos or study earthquakes to determine the composition of Earth.

  13. They study earthquakes, seismic waves and sections of earths mass.

  14. They study the ocean floor, volcanos, earthquakes and it gives them an idea of the earths structure.

  15. They study volcanoes and earthquakes to understand the composition of earth.

  16. They take core samples all over the earth and study them to find the earths composition.

  17. Scientists study earthquakes, when they pass through the earth they create seismic waves that are measured to determine the composition.
