Seismic waves help scientists understand Earth's layers by:
- Scientists can observe how seismic waves change speeds when passing through different layers.
- Scientists can observe which seismic waves cannot pass through certain layers.
<h3>What are Seismic waves?</h3>
These are waves which are generated as a result of the movement of
materials in the earth. They change speed as a result of the collision with
materials in the earth and know the types of material present as a result of
some types not being able to pass through certain medium.
