Sediments may include: fragments of other rocks that have been worn down into small pieces, like sand, organic materials, or in other words, the remains of once-living organisms, or chemical precipitates, which are materials that get left behind after the water evaporates from a solution. Most sediments settle out of water (Figure 4.11).Chalk is an extremely soft sedimentary rock that forms under the sea due to the gradual accumulation of plates of calcite (a mineral form of calcium carbonate) and very small amounts of clay and silt.

Fossils are the remains of living things, or evidence of once living things.Chalk can be classified based on various criteria, such as its chemical composition, texture, color, and historical uses. It is categorized as a biogenic sedimentary rock, as it forms from the remains of living organisms. Chalk is white or pale gray, fine-grained, and soft, with a powdery texture.chalk, soft, fine-grained, easily pulverized, white-to-grayish variety of limestone. Chalk is composed of the shells of such minute marine organisms as foraminifera, coccoliths, and rhabdoliths. The purest varieties contain up to 99 percent calcium carbonate in the form of the mineral calcite.
