Characteristics and Types of Sedimentary Rocks Quiz

Breccia is a type of sedimentary rock characterized by poorly sorted, angular gravel-sized particles. Conglomerate, Sandstone, and Shale are also types of sedimentary rocks, but they have different characteristics and formation processes.

Chert is a sedimentary rock that forms from well-sorted mud through the processes of diagenesis. Limestone is formed from the accumulation of calcium carbonate, sandstone is formed from sand-sized minerals, and shale is formed from clay and silt particles.

In geology, 'well sorted' refers to sediment particles that are similar in size and shape. Coal is an example of a well-sorted material where the carbonaceous deposits are homogenous in composition.

Poorly sorted, rounded, gravel typically describes conglomerate, a sedimentary rock made up of large rounded clasts in a finer-grained matrix. Shale is a fine-grained sedimentary rock composed of mud, Sandstone is composed of sand-sized grains, and Siltstone is composed of silt-sized grains.

Coquina limestone is made up of shell fragments and exhibits angular, poorly sorted grains. Sandstone is typically well-sorted and contains sand-sized grains. Shale is characterized by fine-grained, layered composition. Basalt is a dark, fine-grained extrusive igneous rock.

Well sorted sand is typically classified as Greywacke due to its composition and grain size distribution.

Limestone is a sedimentary rock primarily composed of calcite, which reacts to acid by fizzing or bubbling. Granite, sandstone, and marble are other types of rocks that do not exhibit this characteristic reaction to acid.

Argillaceous Sandstone is formed from sand that is well sorted and is composed of mostly quartz grains. Granite is an igneous rock, shale is a fine-grained sedimentary rock, and conglomerate is composed of larger clasts in a matrix.

Well sorted mud typically forms shale due to the compaction and cementation process. Sandstone is formed from well sorted sand, limestone is formed from calcium carbonate, and gneiss is a metamorphic rock.

Siltstone is a type of sedimentary rock that is formed from well sorted mud. Sandstone is formed from sand, shale is formed from clay and silt particles compacted together, and limestone is formed from the remains of marine organisms.

Poorly sorted, sand, and angular characteristics are typical of arkosic sandstone, which is a type of sandstone rich in feldspar.

Well sorted, angular, sand typically describes quartz sandstone which is a sedimentary rock composed primarily of quartz particles. Shale is a fine-grained sedimentary rock, gneiss is a metamorphic rock, and marble is a metamorphic rock composed of calcite or dolomite crystals.

Furruginous sandstone is a type of rock formed from well-sorted sand, while the other options are formed from different types of sediment or minerals.

Well sorted, containing fossils, and composed of mud are all characteristics of sedimentary rocks, specifically carboniferous shale.

Fossiliferous limestone is a type of rock that contains fossils and is often used for intermediate sorting. Granite, obsidian, and schist do not have the same characteristics as fossiliferous limestone.

Travertine limestone is a type of sedimentary rock known for its distinct orange color and layered structure. Sandstone, shale, and gneiss are also types of rocks, but they do not typically exhibit the same orange coloration and layering as travertine limestone.
