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.
People that live in a desert region can easily find rocks on the surface. These rocks lay on a surface of clay that is also a product of weathering rock. Weathering is the process of breaking down rocks and minerals into smaller pieces by water, wind, and ice. Sedimentary rocks are formed from the breaking apart of other rocks (igneous, metamorphic, or sedimentary rocks) and the cementation, compaction and recrystallization of these broken pieces of rock.
