How's your knowledge of Earth's geology? Flat, round or global?

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

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 discovered portions of the Earth's crust sinking into the mantle beneath California's Sierra Nevada mountains ...

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 ...

This layer of the atmosphere is notoriously difficult to study, but new research sheds light on its mysterious processes.

The Earth's mantle isn't just a hot, dense layer of rock; it's a dynamic and diverse engine driving our planet's geology.

Many parts of Earth are covered and protected by a layer of organisms called a biocrust. The layer acts as a skin for the Earth, protecting landscapes and reducing long-term damage. But climate ...
