Detailed explanation-1: -The lithospheric plates “float” on the asthenosphere and move about the Earth’s surface. Some plates carry whole continents with them. The theory that describes these plates and their movement is called plate tectonics. At the mid-ocean ridges, new rock is produced by volcanism and the plates move away from each other.

Detailed explanation-2: -Because of the high temepratures the rock of the asthenosphere behaves in a plastic way. In effect, the lithosphere floats on the asthenosphere “carrying” the lithospheric plates that are constantly changing position.

Detailed explanation-3: -In plate tectonics, Earth’s outermost layer, or lithosphere-made up of the crust and upper mantle-is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Detailed explanation-4: -The lithosphere floats on a layer of hot magma called the asthenosphere. The asthenosphere has a convection current, made by magma swirling around in a circular motion, from top to bottom. The convection current is what makes the plates move.

Detailed explanation-5: -Answer. Answer. Explanation:The plates “float” on the soft, plastic mantle which is located below the crust.
