Exploring the Science Behind Earthquakes

The video explains earthquakes, their causes, and frequency. It covers Earth's structure, tectonic plates, and how their movements lead to earthquakes. The Ring of Fire is highlighted as a major earthquake zone. The video also discusses measuring earthquakes using seismographs and provides a hands-on activity to create a seismograph model.
