Which part of the brain processes inputs received from the cerebral motor cortex, brain stem nuclei, and various sensory receptors, and then uses this information to coordinate somatic motor output so that smooth, well-timed movements occur?

The part of the brain that processes the inputs of  the brain received from the cerebral motor cortex, brain stem nuclei, and various sensory receptors, and then uses this information to coordinate somatic motor output so that smooth so that well timed moments will occur is the cerebellum.

The brain is divided into three major portions they are the cerebrum, cerebellum and the hypothalamus this is located at the top of the brain and is completely divided into 2 major halves.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
