The Rock Cycle
the processes by which rock is formed, modified, transported, decomposed, and reformed as a result of the Earth's internal and external processes.
The chemical and physical breakdown of rocks exposed to air, moisture, and organic matter.
rock is physically broken up, but there is no change in the mineral content or chemical composition.
the decomposition of rocks and minerals as a result of chemical and biochemical reactions.
A type of chemical weathering that is leads to the change in silicate minerals to salt and clays.
If there are many cracks or joints in a rock, water can get in and weather rocks more quickly through its
A succession of zones within a soil profile with distinct physical, chemical, and biological characteristics.
The transportation of regolith from one place to another and abrasion of the Earth's surface by materials being transported.
Erosion by wind
Wind cannot move sediments that are as large as water can carry. Sorts sediment better than water.
Uplift of surface rock and regolith as a result of the freezing of subsurface water to form ice.
produced from weathering products of pre-existing rocks or accumulated biological matter.
Sediment must be preserved, as by burial with additional sediments, in order to become and sedimentary rock.
Iron-rich siliceous sediments precipitated out of anoxic sea water more than 18 billion years ago.
Carry a lot of sediments in every size of clast. Deposits can be well to poorly sorted, to graded beds.
Generally well-sorted sediments or graded beds in deltas that form when streams flow into a lake.
Wind blown sediments. Best sorted sediments because only smallest grains are carried by normal winds.
The mineralogical, chemical, and structural adjustments of solid rocks to physical and chemical conditions at depths below the region of sedimentation and diagenesis.
occurs when rocks are heated and chemically changed by the intrusion of a body of hot magma.
of an extensive area of the crust as a result of the stresses and high temps associated with plate convergence, collision, and subduction.
