Understanding Earthquakes and Earth's Crust

The video explains that everything around us, including the ground, is constantly moving. It introduces the concept of earthquakes, which occur when the Earth's crust, made up of moving plates, shifts. The Earth's structure is likened to a layered cake, with the crust being composed of plates that fit together like a jigsaw puzzle. These plates move slowly, but when they get stuck and pressure builds up, it can lead to earthquakes. Faults, where plates meet, are key locations for these events. The video concludes by inviting viewers to ask questions and engage with the content.
