Question

1. which layer of earth is made up of the tectonic plates, which hold and move the continents and oceans?

the asthenosphere
the mesosphere
the outer core
the lithosphere

Explanation:

The lithosphere is the rigid outer layer of the Earth. It is composed of the crust and the uppermost part of the mantle. Tectonic plates are large sections of the lithosphere. These plates move over the more ductile asthenosphere (a layer below the lithosphere). The mesosphere is a layer in the Earth's interior below the asthenosphere. The outer core is a liquid layer composed mainly of iron and nickel.

Answer:

the lithosphere
