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.
Textures are separated into foliated and non-foliated categories. Foliated rock is a product of differential stress that deforms the rock in one plane, sometimes creating a plane of cleavage. For example, slate is a foliated metamorphic rock, originating from shale.Non-foliated rock does not have planar patterns of strain. Rocks that were subjected to uniform pressure from all sides, or those that lack minerals with distinctive growth habits, will not be foliated.Where a rock has been subject to differential stress, the type of foliation that develops depends on the metamorphic grade.ocks that were subjected to uniform pressure from all sides, or those that lack minerals with distinctive growth habits, will not be foliated.
