Sedimentary Rocks and Processes

How does the sedimentary rock are formed? There are five basic steps involved in the formation of sedimentary rocks: Weathering: making the sediment by breaking down or dissolving preexisting rocks or living organisms. Erosion: picking up the sediment by water, wind, or glaciers Transportation: moving the sediment by water, wind, or glaciers. …

4.4: Sedimentary Rocks

We can classify sedimentary rocks in two broad categories: clastic and chemical. Clastic sedimentary rocks are made from fragments of eroded bedrock and sediment, which is usually derived from physical …

Sediment Transport and Deposition » Geology Science

Sediment transport and deposition are key processes in sedimentology that govern the formation of sedimentary rocks. The movement of sediment can occur through a variety of mechanisms, including wind, water, ice, and gravity. ... In this process, larger sediment particles, such as gravel and sand, are picked up by the force of the water and ...

Overview of Sedimentary Rocks – Laboratory Manual for …

Weathering and Erosion. Sedimentary rocks are formed by the weathering, erosion, deposition, and lithification of sediments. Sedimentary rocks can be composed of pieces of other rocks, which are broken down by the process of weathering.. Weathering occurs in two different ways: First, rocks can be physically broken into smaller pieces (e.g. two …
