Earth has four primary layers: the crust, mantle, outer core, and inner core. The crust is a thin, solid layer upon which all life resides. Underneath it is the mantle, a hot, dense layer of ...

The Mesosphere is the layer where meteors burn up, and it extends from about 50 km to 80 km (31-50 miles) ...

Water from both volcanic rocks and deep mantle melted Earth's crust 1.6 billion years ago. This long-lasting melting formed ...

Scientists have discovered massive underground oceans trapped beneath Earth’s crust, potentially containing more water than all surface oceans combined—reshaping what we know about earthquakes, ...

Scientists found new evidence that Earth’s crust is peeling underneath the Sierra Nevada in California. The process might be how the continents formed, they say.

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

The oldest crust on Earth, known to be unchanging, is actually being altered in real time. The North American continent is ...

Scientists have discovered unusual deep earthquakes under the Sierra Nevada. This may indicate a peeling process in the Earth ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet ...

Earth’s uppermost layer, the lithosphere, is made up of the rigid crust and the top part of the mantle, which is in a denser, but more fluid state. This layer also contains Earth’s oceanic ...
