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 ...

Earth's outer core has a radius of around 2,160 miles (3,480km) - making it slightly larger than Mars.

As such, they aren’t ruling out other possibilities. But, for now, the signs point towards the remains of an ancient structure, possibly an ocean floor, surrounding Earth’s core.

Our knowledge of what lies beneath Earth's crust has been inferred mostly from what volcanoes have divulged and what seismic waves have whispered. From these indirect observations, scientists have ...

The Earth's outer core, a band of fluid metal roughly 1,400 miles thick, is composed of mostly iron and nickel. Scientists believe the volatile swirling of this ferrous liquid generates the planet ...

Scientists have unravelled a doughnut-like structure buried deep within Earth's swirling outer core of molten metal. The exciting discovery was reported in a new study published in Science Advances.

Earth's diameter is about 12,750 kilometers. The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner ...
