Topmost layer of the earth.
Composition of Layer: Solid

-2 parts: Oceanic and Continental
-Least pressure of all layers
-Coolest layer
-Least dense layer
-Least pressure

The deepest hole in the crust, made by humans, is 7.5 miles.

Center of the earth.
Composition of layer: Solid

-Hottest layer of the Earth
-Most dense layer of the Earth
-Most pressurized layer of the Earth
-Made of Solid Iron

The inner core is the hottest layer of the earth, even hotter than the surface of the sun at a stunning temperature of 7600 degrees Farenheit.
