<u>Answer:</u>
The seismic waves that stay on the Earth's surface are called surface waves.
<u>Explanation:</u>
- The waves that are formed near the Earth's surface and are sandwiched between the surface of the Earth and the atmosphere are known as surface waves.
- These waves are not absorbed back by the surface or do not even mix up with the atmosphere easily.
- Thus they stay on the surface of the Earth for a long time after they are generated.
