Answer:
- body waves
- surface waves
Explanation:
The earthquakes produce two major types of seismic waves, body waves and surface waves. The body waves are the seismic waves that travel through the layers of the Earth. The surface waves are the waves that only travel on the surface of the Earth and the surface of the water bodies. The earthquakes are a natural phenomenon that occurs most at places where there is more intense geologic activity. Because the crust is cracking and breaking deep inside, lot of adjustments occur, and through the adjustments, lot of energy is released, which is manifested through these two types of waves.
