Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

The discovery of giant creatures in the Earth’s crust beneath the ocean floor serves as a powerful reminder of the wonders that still await us in the unexplored corners of our planet.

Where continents rift apart, new crust is formed from upwelling magma. Eventually, a new ocean basin forms. In this web focus we present opinion pieces, along with research and overview articles ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.

The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 ...
