A rigid layer made up of the upper most part of the mantle and the crust is called the

• lithosphere

• asthenosphere

• geosphere

• biosphere

The soft layer of the mantle on which the lithosphere floats is called the

• lithosphere

• asthenosphere

• geosphere

• biosphere

The asthenosphere is: (Choose all that apply!!)

• beneath the lithosphere

• supports movement of the tectonic plates

• a dense sphere of solid iron and nickel at the center of the Earth
