Document Summary
Sedimentary rock - rock composed of the transported remains of pre-existing rocks, i. e. sediment. Sediment: material derived from the weathering of preexisting rock. General life history of sediment: in order to make a sedimentary rock, four things need to happen: Granite weathering: weathering: the mechanical and chemical breakdown of rock into: transportable fragments or ions in solution. Microcosm of sedimentation: transport: physical movement of the products of weathering by some agency. Material may be transported as fragments or in solution. Tiny delta in outwash stream: deposition: the process of depositing the sediment. For solid fragments, this involves deposition is some sort of topographic basin. Landslide scar and deposit: mass wasting: wherever there is a topographic slope, the is the potential for loose material to slide down it under the influence of gravity. This applies whether the slope is on land or in the ocean basins.
