Which of the layers of the Earth has the following three characteristics? i. It is made of molten rock. ii. It has currents that are constantly moving. iii. Earth’s plates float on top of its currents.

The mantle lies beneath Earth’s crust and moves slowly through convection currents. Earth’s plates ride on the upper mantle, especially its soft, flowing asthenosphere. Although the mantle is mostly solid rock rather than entirely molten, it can flow over long periods, so the best choice is the mantle.
