Explore Earth's hidden layers beneath our feet. This kid-friendly guide includes a neat diagram and fun descriptions of the 4 layers of the Earth.

There are 4 layers in Earth generally speaking. However, it depends how you measure each layer, based on physical or chemical properties. What is the depth of the inner core of the Earth?

Scientists previously believed the Earth has four layers. New research says there may actually be five. By Matthew Rozsa. Published March 4, 2021 5:27PM (EST) ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more ...

The authors suggest that this could have been formed by a change in the Earth's magnetic field, which in turn may re-shape the way we think the Earth was formed 4.5 billion years ago.
