The Science Behind Volcanoes: Exploring Plate Tectonics and Eruptions

The video explains the origin of the term 'Volcano' and delves into the science of plate tectonics, describing the Earth's structure with its molten core, crust, and shifting stone plates. It details how cracks between plates allow gas and heat to escape, leading to the formation of volcanoes. The process of volcanic eruptions is explained as a result of temperature and pressure imbalances. The video also covers the properties of magma, highlighting its lower density compared to solid rock, causing it to rise and eventually lead to volcanic activity.

Why does the Earth sometimes need to release pressure?
