In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.
processes is much more common than that formed by inorganic processes. Limestone composed of skeletal fragments of marine invertebrates is quite common. Both coquina and fossiliferous limestone contain abundant skeletal material. Coquina, however, contains much pore space, but pores of fossiliferous limestone are filled with cement and mud.
Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as ...
