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.
