The layers of Earth provide geologists and geophysicists clues to how Earth formed, the layers that make up other planetary bodies, the source of Earth's resources, and much more. Modern advances ...

The layers of Earth diagram. Trevor Nace Layers Of Earth 1. Crust. Earth's crust is what we walk on every day. It is the thin (relatively) outermost layer that wraps around the Earth and ranges in ...

The first layer is the crust, a thin outer shell that extends about 18 miles (30 km) below the planet's surface. The next layer, the mantle, stretches about 1,800 miles (2,900km) below Earth's ...

A diagram of the Earth's layers, including the transition zone – the bottom boundary of which has now been found to be quite jagged. Kyle McKernan, Princeton Office of Communications.

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.

The inner core of the Earth appears to hold an innermost secret. Geology textbooks almost inevitably include a cutaway diagram of the Earth showing four neatly delineated layers: a thin outer ...

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 ...
