The Earth's crust, which includes all the continents and ocean basins, is divided into several pieces known as tectonic plates. These plates collide with, pull away from, and slide alongside each other as they move around on top of a _______, _______, more gradually deformable layer of the Earth. A. less dense; hotter B. denser; colder C. less dense; colder D. denser; hotter

Respuesta :

Answer: D

Explanation:

Currently the continents and ocean basins all float on the mantle, the layer beneath the crust, which flows like putty. Deep parts of the mantle heat up, and rise, and as they do they cool down, sinking again, creating huge circular currents. The currents push and pull the tectonic plates across Earth's surface.
