M any people envision Earth’s structure as a tidy, layered system: the thin crust on the surface, the thick mantle below, and the core at the center. But beneath our feet lies a world far more ...

Scientists have been investigating colossal structures that exist deep inside of Earth's mantle beneath Africa and the ...

The mantle, by contrast, was seen as little more than a thick layer of hot rock, with the occasional plume pushing its way through. Now, the team on this new effort reports that a lot more is ...

On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic core of our planet. The mantle is ...

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 different layers. The upper ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

The three-kilometre-thick ice sheet covering Mars's north pole is young, formed between 2 and 12 million years ago. The ice sheet is bending the rocky crust beneath at a rate of 0.13 millimetres per ...
