Is chalk a sedimentary rock

Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor .

Clastic sediment is the solid bits and pieces of rocks and minerals that have broken down from the source rock by a combination of physical and chemical weathering. Clastic sediment is sometimes called detrital sediment. Grains of clastic sediment range in size from microscopic (clay particles) to house size (large boulders), with sand and silt ...Sedimentary rocks often form porous and permeable reservoirs in sedimentary basins in which water and important minerals such as oil can be found. Chalk is a valuable resource and much of it is quarried for the construction industry where it is used in the making of cement.

Though the continental crust has greater thickness it is less dense than the oceanic crust. 2. Deccan plateau is made up of only granite rocks. 3. Granite rock is an example of extrusive igneous rocks. 4. Limestone, sandstone and coal are examples of sedimentary rocks.Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. These rocks often have distinctive layering or bedding and create many of the picturesque views of the desert southwest.

Article Vocabulary Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.Coal is a sedimentary rock usually occurring in rock strata in layers or veins called coal beds. Coal is a fossil fuel that forms when dead plant matter is converted into peat, which in turn is converted into lignite, bituminous, and anthracite.

Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.Chalk is a soft, white, porous sedimentary carbonate rock, a form of limestone. Cretaceous in age. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-organisms called coccolithophores. It is common to find chert or flint nodules embedded in chalk.

Floor 1. Metamorphic rocks form when sedimentary, igneous, or pre-existing metamorphic rocks are changed by heat, pressure, and chemically reactive waters. These rocks are identified by their minerals and texture. During metamorphism, new minerals grow, with different sizes, shapes, and orientations than those of the original minerals.Organic sedimentary rocks. Forms from remains of plants and animals. Not made of minerals, minerals are inorganic. Examples of organic sedimentary rocks. Fossiliferous Limestone. Coal. Coquina. Fossiliferous limestone. Limestone with alot of fossils.
