Question

Choose the correct statement about seismic waves:

• A. These are mechanical wave
• B. These can be either longitudinal or transverse.
• C. These are electromagnetic wave
• D. These waves are a result of big explosion, earthquakes, and volcanic explosion.

Answer 1

Answer: (A), (B), (D)

The correct options are
A

These are mechanical wave

B

These can be either longitudinal or transverse.

D

These waves are a result of big explosion, earthquakes, and volcanic explosion.

Seismic waves are waves that travel through the Earth's layers and is a result of earthquakes, volcanic eruptions, magma movement, large landslides and large man-made explosions. These waves carry energy which is transported through the earth and over its surface by means of both transverse and longitudinal waves.

It requires a material medium for its propagation, so it is a mechanical wave.
