Describe how you can use earthquake vibrations to prove the inside of the Earth is made of separate layers

Answers

Answer:

Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.

Seismic waves are recorded by a machine called a seismograph, which tells us about the strength and speed of the seismic waves. Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth's internal structure.

Explanation:

Does this help??

Answer:

Seismic waves

Explanation:

Seismic waves provides evidence for the internal structure of the Earth, which cannot be observed directly. Seismic waves from large earthquakes are detected around the world. Their paths are curved as the waves refract due to the gradually changing density of the layers.
