Now Put ALL the layers of Earth in order from outermost (top) to innermost (bottom)

1 answer

Sure! The layers of Earth from outermost (top) to innermost (bottom) are:

1. Crust - The Earth's thin, outermost layer that consists of solid rock. It is divided into two types: continental crust (thicker and less dense) and oceanic crust (thinner and denser).

2. Mantle - The layer beneath the crust, extending to a depth of about 2,890 kilometers (1,800 miles). It is composed of solid rock but can partially melt in certain regions. The mantle is further divided into the upper mantle and lower mantle.

3. Outer Core - This layer lies beneath the mantle and extends to a depth of about 2,400 kilometers (1,500 miles). It is predominantly composed of liquid iron and nickel.

4. Inner Core - The innermost layer of Earth, located at the center. It is primarily composed of solid iron and nickel due to high pressures despite extremely high temperatures.

So, the order from outermost to innermost is Crust, Mantle, Outer Core, and Inner Core.
