Sedimentary rocks are lithified sediments, the origin of which may be from igneous, metamorphic, or other sedimentary rock, and in some cases chemical solutions or organic matter. Erosion and weathering of rock creates a range of rock particles from boulder sized to microscopic. These particles are transported by wind, water or landslide to a point of deposition or resting place. If these particles continue to be covered with additional layers of particles, the compression from the weight above, will, in time remove most of the water from the sediments. As the water is removed, cementing minerals, such as calcite or quartz, solidify from the remaining solution and fill in the gaps between the particles. The result is a lithified sediment, better known as sedimentary rock.

How would you describe a sedimentary rock?

Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main ways-by the deposition of the weathered remains of other rocks (known as clastic sedimentary rocks); by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks include common types such as chalk, limestone, sandstone, and shale. :)
