Document Summary
Investigate the significance of sedimentary rocks for investigating earth history. While underground igneous and metamorphic rock comprise 90 to 95 percent of all rocks, the most common type at the surface are sedimentary rocks. The movement of sediments across the surface of the globe are recorded in the rocks and can be used to learn about earth history. Fossils are one important way sedimentary rocks reveal the past. 7. 2 origins of sedimentary rocks: learn the three different types of sedimentary rocks, explain how weathering and sedimentary rocks are related. The formation of sedimentary rocks is described in the rock cycle. The processes in the rock cycle that happen near the surface of the earth involve sedimentary rocks. Weathering breaks down rocks in different ways; the particles that result from weathering are eventually what make up sedimentary rocks. The sediments may move from their original location before they are turned into rocks.
