is the science that analyzes the cause of earthquakes and the propagation of waves within Earth and on its surface.

The science that analyzes the cause of earthquakes and the propagation of waves within Earth and on its surface is called Seismology. Here are the steps:

1. Seismology starts with the study of earthquakes and their causes. This involves understanding the tectonic forces that cause the Earth's crust to deform and fracture, leading to earthquakes.

2. Seismologists also study the propagation of seismic waves. These are the waves of energy that travel through the Earth's layers when an earthquake occurs.

3. These waves can be detected and measured by seismographs. By analyzing the data from these instruments, seismologists can learn a lot about the earthquake, such as its location, depth, and magnitude.

4. The propagation of seismic waves also provides valuable information about the Earth's internal structure. By studying how these waves change as they travel through different layers of the Earth, seismologists can infer what these layers are made of.

5. Finally, seismology also involves the study of seismic activity on the Earth's surface. This includes phenomena like landslides, tsunamis, and volcanic eruptions, which can all be triggered by earthquakes.
