What are the major layers of the earth?
1 Answer
There are four major layers.
Explanation:
They are...
The Crust:
- Very thin
-
The part you live on top of
-
Separated into plates (when they knock against each other Earthquakes happen.)
The Mantle:
-
The largest layer (1800 miles thick)
-
Flows because of very high temperatures
-
The movement of the plates is caused by this flowing
The Outer Core:
-
Composed of the metals Nickel and Iron
-
Completely liquid because of extremely high temperatures (4000-9000 degrees Fahrenheit)
The Inner Core:
- Temperatures and pressures are so high that the metals are squeezed together and are not able to move about like a liquid, but are forced to vibrate in place as a solid.
Note that some of these layers can be broken down and described further.
