Tectonic plates are pieces of the that float on the more fluid below. A. mantle; crust B. asthenosphere; lithosphere C. crust; lithosphere D. lithosphere; mesosphere E. lithosphere; asthenosphere

The answer is E.) Lithosphere, Asthenosphere.

Explanation:

Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.

From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:

i) the crust

ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)

iii) the outer core

iv) the inner core.

The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers

( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.
