WebCoal, oil and natural gas typically form in sedimentary rocks. When carbon-rich organic materials, such as leaves, are deposited in stagnant water such as a bog or swamp with a low oxygen content it may not fully decay. If this happens and sediment is deposited on top, a coal bed can eventually form.

WebAll are inorganic sedimentary rocks Limestones ( inorganic)form when chemical changes/high water temp increase water's concentration of calcium carbonate to the point that it precipitates. When travertine (limestone) commonly seen in caves,is deposited in caves, groundwater is the source of the calcium carbonate. For decades, it was thought that the majority of the organic-rich sedimentary beds deposited on the ocean floor was a byproduct of three environmental variables: the input of organic material, the rate of sedimentation, and the amount of deep-water oxygenation. These variables are linked on spatial and temporal scales by climate, ocean currents, and sea-level at the time of deposition. Any changes in the variables or the parameters that link them will result in different sedimentary …
