The correct answer is slate.
Seismic waves travel faster in slate. They are waves of energy that move through earthquakes. The way seismic waves travel through the earth’s surface is very similar to the way other types of waves travel (water, light, sound) through the earth‘s surface.
<h2>Further Explanation</h2>
Seismic waves are energy waves that move through the earth when earthquakes occur. The ground vibrates during earthquakes and it is the movement of seismic energy that causes the vibration.
There are two types of seismic waves and these include
- Surface waves
- Body waves
The body waves are types of seismic waves that move through the Earth’s interior. That is, they travel under the ground.
Surface waves are also the type of seismic waves that travels through the Earth’s surface. This type of wave travels on the earth’s surface. Surface waves are rolling motions that contribute to most of the damages whenever earthquakes take place.
However, body waves can be classified into two, and these include
- Primary waves
- secondary waves
Primary waves are very fast and can moves at 7km within seconds.
Secondary waves are not as fast as primary waves and travel in different actions. Secondary waves travel at about 3.5 km per second.
