|
sedimentary Rock
|
Made of combination of detrital, chemical, or biochemical material .
|
|
|
Detrital material
|
mineral grains or rock fragments derived from the process of mechanical weathering that are transported and deposited as solid particles (sediment).
|
|
|
chemical material
|
dissolved in water and later precipitated by either inorganic or organic processes or formed from the evaporation of water.
|
|
|
Biochemical material
|
is the result of the life processes of water - dwelling organisms for example, the formation of a shell- or plant life.
|
|
|
weathering
|
the physical breakdown (disintegration) and chemical alteration (decomposition) of rocks at or near Earth's surface.
|
|
|
mass wasting
|
the transfer or rock and soil down slope under the influence of gravity.
|
|
|
Erosion
|
the physical removal of material by mobile agents such as water, wind or ice.
|
|
|
mechanical weathering
|
accomplished by physical forces that break rock into smaller pieces w/o changing the rock's mineral compostion.
|
|
|
chemical weathering
|
chemical transformation of rock into one or more new compounds.
|
|
|
Frost wedging
|
is a form of physical weathering that involves the repeated freezing and thawing of water in areas with extremely cold weather. When water freezes, it expands. If you have ever used ice cube trays you may have noticed this.
|
|
|
earthquake
|
is ground shaking caused by the sudden and rapid movement of one block of rock slipping past another along fractures in earth's crust called faults.
|
|
|
fault
|
are locked, except for brief, abrupt movements when sudden slippage produces an earthquake.
