Document Summary
They account for about 5%(by volume) of earth"s outer 10 miles. 4 steps to forming sedimentary rocks (3) deposition (4) lithification diagenesis. The process by which sediment becomes sedimentary rocks. Rock types are based on the source of the materials. Void space, the volume being stored in a natural resource, passing through the space. Size of the grains=energy of the body system. Transportation reduces the size and angularity of particles but does not change their general shape. The pore space are filled in and compressed by the bodies of grains/sands. Precipitated minerals of the pore space by product of grains. The pore space gets lower because it ger compromised by the amount of product of grains. Measure of the ease with which a fluid flows through a rock. Oil: trap ideal reservoir rock has high porosity and permeability. Grain size variability in a sample of sediments or rocks. Creates a void space by the water"s high pressure.
