Question

How do seismic waves help scientists understand Earth's layers? Select the two correct answers. (1 point)

Answer 1

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.

What are Seismic waves?

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.
