It creates the Earth's magnetic field and is about 1,400 miles (2,300 kilometers) thick. The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot ...

Its thickness varies greatly from place to place, with some regions even lacking a D" layer altogether—much like continents rise above the Earth's oceans. These intriguing variations have ...

Beyond the outer core lies the mantle, a 1,800-mile-thick layer of viscous molten rock on which Earth's outermost layer, the crust, rests. On land, the continental crust is an average of 19 miles ...

known as the D" layer, is about 1,900 miles underneath the Earth's surface, resting between the liquid outer core and the ...

It is made of liquid iron. Mantle The mantle is the layer of the Earth which makes up 84% of its volume. It is also the thickest section at approximately 2900 km thick. The mantle is made up of ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

Scientists have always been curious about the atmosphere surrounding us, but in the past, they could not just hop on a spaceship to see what was up there. Instead, scientists hiked up high ...
