Chalk: A biological limestone formed from shell debris

Chalk is widely known among the people of western Europe and a few other parts of the world because it is a bright white rock that can form vertical cliffs along shorelines The chalk cliffs are eroded at water level by wave action, and as the base of the cliff is undercut, collapses occur when the undercutting reaches a vertical joint or other plane of weaknessSedimentary 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 cementSedimentary Rocks | Revision WorldChert is a microcrystalline or cryptocrystalline sedimentary rock cloth composed of silicon dioxide (SiO2) It takes place as nodules, concretionary hundreds, and as layered deposits Chert breaks with a conchoidal fracture, often producing very sharp edgesNonClastic Sedimentary Rocks » Geology Science

Sedimentary Three Different Types of Rocks

• Sedimentary rocks are made of sediments that have settled into layers •Sediments are moved by water and wind –They pile up in layers –Sometimes these layers are on land, but often they are at the bottom of an ocean, river, or lake22102019· Sedimentary rocks can be organized into two categories The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris The other is chemical rock, produced from the dissolution and precipitation of minerals Detritus can be either organic or inorganic Organic detrital rocks form whenSedimentary Rocks | National Geographic SocietyChalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of submicroscopic plankton which had fallen to the sea floorChalk isChalk Wikipedia

Chalk is a very fine‐grained bioclastic limestone composed of accumulations of skeletal debris from tiny marine organisms that drifted down to the ocean floor All of these “redeposited” limestones could be considered clastic sedimentary rocks, as well as organic sedimentary rocks Dolomites Limestones are frequently converted into dolomites, or dolostones, during the early stages ofSedimentary rocks can be organized into two categories The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris The other is chemical rock, produced from the dissolution and precipitation of minerals Detritus can be either organic or inorganic Organic detrital rocks form whenSedimentary Rocks | National Geographic SocietySedimentary Rocks (Clastic Rocks (Limestone (Chalk, Oolitic, Bioclastic),: Sedimentary Rocks (Clastic Rocks, Sedimentary Structures, Texture, Diagnesis, WeatheringSedimentary Rocks (Clastic Rocks (Limestone (Chalk
