Answer to Question 1

Answer: FALSE

Answer to Question 2

Answer: Origin, texture, and composition of sediment grains form the basis for sedimentary rock classification. Clastic rocks are classified primarily according to sediment texture, especially grain size, and secondarily according to composition. Clastic sediment texture relates to the strength and steadiness of currents transporting the sediment and the distance of transport. Clastic sediment composition reveals the source rock that weathered to create the sediment and the extent of weathering. Chemical and biogenic sedimentary rocks are classified primarily according to dominant composition and consist of sediment produced by inorganic chemical precipitation, biologic processes, or both. Some rocks, such as limestone, form by both inorganic and biologic chemical processes.
