hey mate,
The lithosphere is made up of rocks from two of the Earth's major layers. It contains all of the outer, thin shell of the planet, called the crust, and the uppermost part of the next-lower layer, the mantle. The thickness of the lithosphere varies it is thickest below the continents and thinnest at the mid-oceanridges, raised areas of the seafloor where new seafloor crust is formed.

As the earth cooled, there was no atmosphere to trap the heat. The surface cooled off fast due to the cold temperature of space (like how the top of coffee cools off when exposed to the air). This created a layer of cooled rock that solidified into the crust. Differences in magma created two types of the lithosphere, oceanic and continental, characterized by the basalt in oceans and granite in the continents.
