Earth's Layers and Tectonic Activity

The video explains how Earth's crust is made up of tectonic plates that move over a thicker layer beneath. These movements can cause the crust to break, forming faults and leading to earthquakes. Most earthquakes occur along the Pacific Ocean's edge, known as the Ring of Fire, where many volcanoes are also found. Earthquakes can also trigger tsunamis. Scientists continue to study these natural phenomena to better understand them.
