China is set to venture where humanity has scarcely been before: beneath the Earth's crust, into its mantle. To achieve this ...

The mantle of the Earth, up to 1,800 miles (2,900 kms) thick and 84% of the Earth's volume, was assumed to be a simple ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

My research focuses on the understanding of the present-day physical and chemical structure of the Earth's mantle and crust as well as its physical and chemical evolution over geologic time. Within ...

His team’s calculations suggest they are caused by waves that ripple through Earth’s mantle, the layer below the crust, when continents divide. They may even be responsible for some of the ...

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 ...
