I WONDER - How Do Earthquakes Occur?

The Earth's crust consists of rock plates that move and interact, causing earthquakes. These seismic events often occur along fault lines, especially in the Ring of Fire, where many plates converge. Earthquakes can lead to avalanches in snowy regions and tsunamis when they occur underwater.

Explain the relationship between fault lines and earthquakes.

What are tsunamis and how are they related to earthquakes?
