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.
Hot water. When fine-grained tabular minerals in a rock at depth are subjected to differential stresses, they what. align perpendicularly to the plane in which the maximum compressive stress is applied. At a mid-ocean spreading center, alteration of rocks by chemically active fluids causes metamorphism by __________.
