Question

Quizplus · Accepted Answer

Shale, which is a fine-grained sedimentary rock, can form in a low energy, quiet environment such as a lagoon or lake bed. Evaporites, such as rock salt and gypsum, can also form in such environments where the water evaporates and leaves behind the minerals. Sandstone and arkose, which are coarser-grained sedimentary rocks, typically form in higher energy environments such as rivers and beaches. Dolomite is a type of limestone that can form in a variety of environments, including marine and freshwater settings.
