Exploring the Science Behind Earthquakes

The video explains how movement is a constant in the world, including the ground beneath us. It introduces earthquakes, describing them as the shaking of the ground due to tectonic plate movements. The Earth's structure is likened to a layered cake, with the crust made of large plates that move slowly. These plates can cause earthquakes when they bump into or get stuck against each other, building pressure until they suddenly move. The video concludes with an invitation for viewers to engage with SciShow Kids.
