How can scientists use the two types of waves (P waves and S waves) that earthquakes generate to develop an

earthquake warning system in the future?

The correct answer is as showed in the Explanation

Explanation:

Seismic waves are waves of energy that are produced due to Earth's layers movement, such as the ones occurring during earthquakes. Scientists developed an early warning system to determine when an earthquake is going to take place by analyzing the behavior of two types of waves: P waves and S waves. P waves are the ones that travel faster and are produced first, they travel in an exact opposite direct of where the earthquake is produced. On the other hand, s waves or secondary waves are slower and travel in a perpendicular way. Scientist detect when these waves are generated in specialized centers.
