Structure of the earth
Mantle
It is 2,900 or 3,000 kilometers thick.
Upper mantle
- It is roughly about 700 kilometers down.
- It is cold enough to be solid, so there is a solid part of the upper mantle
- It is able to move easier because there's less pressure.
Lower mantle
- Just below the lithosphere, the temperatures are high enough to be a deformable solid or magma.
-
-
- Every molecule here wants to go downward because of gravity. So it's applying pressure downward.
Lithospere
- It is the combination of the solid part of the upper mantle and the crust
Core
It is considered that is the center of the earth and the deeper you go, the more pressure you get
Outer core
- The thickness is approximately 2,300 kilometers
- Composed primarily of nickel and iron.
- It has temperatures high enough that nickel and iron can melt.
- State liquid, the pressures are low enough that they can still be in a fluid state.
Inner core
- It is about 1,200 kilometers thick
- Composed primarily of nickel and iron.
- The temperature is really, really, really hot, the pressure is so big that the molecules can't flow past each other.
- It cannot be liquid. It is solid.
