Learn the difference between continental crust and oceanic crust with a detailed comparison of thickness, density, ...

Oceanic transform faults are strike-slip boundaries—faults that move horizontally rather than up and down and connect offset ...

Image: Tiny crystals called zircons are used to date oceanic crust. A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of ...

In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...

The natural structure of the rigid oceanic crust that forms a shell around Earth contains cracks and faults. These fissures are hydrothermal pathways for heat, water, and chemical solutions to move ...

A hidden, razor-sharp "microplate" could be fueling earthquakes in Alaska.

Earth's middle layer is chunky, like peanuts in a sea of caramel. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In Geology 101, Earth's ...

An international research team has discovered that a subduction zone's age affects the ability for it to recycle water between the Earth's surface and its inner layers. The more mature the subduction ...

The Earth’s crust is disappearing beneath our feet – and most people don’t even realise it ...

In Geology 101, Earth's interior is divided into neat layers, like a sugar-coated jawbreaker. But it turns out that parts of the planet's middle layer might be more like peanuts in a sea of caramel.
