Core Terms: Passive Solar Design
The Earth's Layers:
Crust
The crust is the outermost of the Earth's layers, excluding those of the atmosphere. It is composed of tectonic plates, which are constantly shifting, albeit gradually. It is thinner under the ocean than it is at sea level, and is thicker at mountains.
Mantle
The mantle is the third most central of the Earth's layers and is composed mainly of various metals, such as iron and aluminium. It has an average temperature of about 2350° Celsius. Convection currents, which are currents caused by the transfer of heat, also known as convection, occur here.
Outer Core
Tho outer core is liquid, which is unique to this layer, and mostly consists of iron and nickel.
Inner Core
The inner core is about the size of the moon and is also mostly made up of iron and nickel.
