Document Summary
Earth and the atmosphere lecture 3 september 26. Material weathers at the surface and is transported mainly by water (liquid or ice (like glaciers it will form all kind of sedimentary deposits as the advance or retreat) though wind can also move material. River picks up sediment, gets down to land that flattens out, then the sediment will drop out) Water can also transport material into spaces and cement materials together. Sedimentary rock very much an indication of surface processes. This includes like as many sediments have fossils or some evidence of life trapped in them. Almost all fossils are buried in sedimentary rock. Sedimentary rock forms in beds or strato. Divided by bedding planes often split easily along these lines. These planes represent changes in conditions that laid down the rock. Main division detrital (small particles) or chemical (includes biochemical) Rock that would form coral skeletons would be: chemical.
