WebJun 16, 2024 · We now know that there are several layers inside the planet, the outermost one being a relatively thin crust, and below that is the mantle; this is a rocky layer that extends 3000km down to the outer edge of the core. The reason we know this is thanks to earthquakes. These send waves of vibrations through the planet. WebA divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to …
