The Continental Crust, Oceanic Crust and very top of Earth's mantle make up a hard surface that breaks into tectonic plates. This layer of the Earth is referred to as the ____________(A)_ and it floats or moves on a melted layer of Earth called the ________________(B)__.

Crust, Mantle

Plates, Lithosphere
Plates, Lithosphere

Lithosphere, Asthenosphere
Lithosphere, Asthenosphere

Lithosphere, Hot Spot

The correct answer is Lithosphere, Asthenosphere. The lithosphere is the rigid outer layer of the Earth, consisting of the continental crust, oceanic crust, and uppermost part of the mantle. The plates, which are broken sections of the lithosphere, float or move on the semi-fluid layer beneath called the asthenosphere.
