Situated between the mantle and the inner core, the Earth's outer core is a liquid layer of the Earth's core. It is mostly made up of iron and nickel, with little amounts of silicon and oxygen ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core, a solid sphere of iron and nickel that ...

Adopted 35 years ago, the Montreal Protocol remains a groundbreaking environmental agreement, credited with saving millions ...

The boundary between the two lies about 465 miles (750 kilometers) beneath the Earth's surface. The crust is the outermost layer of the Earth. It is the familiar landscape on which we live ...

A supernova close enough to Earth could strip the ozone layer and cause mass extinction, but no immediate threat exists.

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 ...

It helps to visualize this: Earth’s inner core is a solid ball that is surrounded by a fluid outer core. This is how it can rotate at a different pace compared to the planet’s outer layers ...
