Plate tectonics (from the Late Latin tectonicus, from the "pertaining to building") is a scientific theory that describes the large-scale motion of Earth's lithosphere. This theoretical model builds ...

A groundbreaking study by ETH Zurich reveals that solid rock in Earth's D" layer, located deep within the mantle, can move like a fluid while remaining solid. Researchers used diamond anvil cells and ...

One explanation for plate movements is slab pull. Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection currents under the ...

For decades, scientists have sought to unravel the mysteries hidden deep beneath Earth’s surface. One of the most puzzling regions has been the D" layer, located about 2,700 kilometres (1,700 miles) ...

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 to ...
