Earth's mantle is split by the Pacific Ring of Fire, an ancient schism that reflects the creation and destruction of the supercontinent Pangaea, a new study finds. One of these sections contains ...

A team of European researchers discovered a new high-pressure mineral in a lunar meteorite which is helping to explain what happens to materials within the extreme pressures of the Earth’s mantle. The ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

When I dug holes as a kid, I was scratching away at the very top of Earth’s crust. The mantle, which lies beneath the crust, ...

Mantle motions have major effects on topography and the distribution of ice sheets. The motions are key for researchers ...

It is unlikely that the Earth's mantle — the layer beneath the crust and above the core — was completely homogeneous when it initially formed. Over time, cooling-induced convection as well as ...

It creates the Earth's magnetic field and is about 1,400 miles (2,300 kilometers) thick. The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot ...

Geophysicists studying seismic waves from earthquakes have found evidence suggesting that Earth's inner core not only rotates ...

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 ...
