One might assume that marine fossils are exclusively unearthed in sedimentary coastal or underwater deposits. This is far ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...

Discover interesting facts about how big earthquakes can get, why earthquakes happen, and why they're so hard to predict.

It is the thinnest layer and is between 5 and 90 km thick ... the crust has cracked and split into many different pieces called tectonic plates. These plates can be oceanic, meaning they're ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

Geology. The presence of oceans, continents and plate tectonics on Earth is most likely the reason there is no evidence for advanced extraterrestrial civilizations, according to new research by ...

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

Most scientists think that's not a coincidence. By dragging huge chunks of crust into the mantle, Earth's middle layer, plate tectonics pulls carbon from the planet's surface and atmosphere ...

The layers can also be categorized into the rigid outer lithosphere (which includes the crust and top portion of the mantle and makes up Earth's tectonic plates) and the athenosphere, the portion ...

Plate tectonics is relatively new ... up of huge slabs of rock called plates that glide over the planet's inner layer, or mantle. As these plates shift, they sometimes collide with other plates ...
