Learn how forces deep underground generate a protective bubble between us and space.

The surprise discovery of earth’s core composition may debunk previous assumptions on the solidity of the planet.

Alternatively, as shown in the diagram, convection currents under the Earth’s crust transfer heat, which rises through the surface and cools back down in a circular motion. The convection ...

The heat from the Earth's core causes convection currents in the mantle. In this process, hot material rises, cools down as it nears the crust, and then sinks again, creating a continuous cycle ...

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 ...

This broad, 8,000-mile-long bulge in the crust of the earth differs in many ways from the rest of the ocean bottom. It may be the result of huge convection currents in the interior By Henry W. Menard ...
