Understanding Earthquakes

The video explores how earthquakes occur, starting with historical beliefs and moving to scientific discoveries. It explains the role of tectonic plates and fault lines, particularly the San Andreas Fault, in causing earthquakes. The video discusses the impact of earthquakes, safety measures, and the ongoing challenge of predicting them. It encourages curiosity and future exploration in earthquake science.

What is a common experience during an earthquake?

• The temperature drops suddenly.

• The sky changes color.

• The ground remains still.

• The ground moves beneath your feet.
