Which laver of the Earth is the mantle?

The mantle is the thick layer of the Earth located between the crust and the outer core. It's about 2,900 kilometers (1,800 miles) deep and makes up roughly 84% of the Earth's total volume. Imagine it as a hot, rocky layer that flows slowly over geological time, allowing tectonic plates to move and shift above it. This dynamic movement is crucial for processes like earthquakes and volcanic activity! Understanding the mantle helps explain the intricate workings of our planet. For example, it's responsible for the convection currents that drive plate tectonics, causing continents to drift over millions of years. This is like the Earth's slow-motion dance, where the floor underneath is constantly shifting. So, the next time you think about earthquakes or volcanic eruptions, remember that the mantle is the unsung hero, orchestrating these epic geological events!
