1 Slowness-bradykinesia (slow movement) and akinesia (inability to move) are common in people with Parkinson's disease. 2  This is a hypokinetic disorder characterized by hypokinesia or akinesia, rigidity, and a rhythmic fine tremor at the rate of 3-6 cycles per second.

The conditions deep in the earth are different enough that these different conditions cause minerals different from those which form at the surface. For example, surface weathering process, which is also a change of the types of minerals causes hard rocks to change into small crumbly pieces.
Stress is the force applied to a rock. There are four types of stresses: Confining stress happens as weight of all the overlying rock pushes down on a deeply buried rock. The rock is being pushed in from all sides, which compresses it. The rock will not deform because there is no place for it to move.
