Cambios en la Tierra: tierra en movimiento

The video tutorial explains natural phenomena such as earthquakes, volcanic eruptions, and geysers. It begins with an introduction to earthquakes, describing them as movements of the earth's crust caused by rock shifts. The tutorial then discusses magma, which becomes lava when it reaches the earth's surface, often through volcanic eruptions. These eruptions can be explosive, ejecting ash and rocks. Finally, the video covers hydrothermal vents and geysers, highlighting the famous Old Faithful geyser in Yellowstone National Park.
