This middle layer is called the mantle. The upper part of the mantle becomes solid. The outermost layer, called the crust, is solid, too. Together, these solid parts are called the lithosphere.
Mantle is the middle layer of the earth lies between crust and core. The average thickness of this layer is 100 to 2900 km. Silica and magnesium elements predominate in this layer so it is known a SIMA. Density of the layer varies between. 3.1 to 5.00. It has two layers: upper mantle and lower mantle.
