Sandstone is made of sand grains (0.05mm to 2mm) that may have been deposited in the sea, by rivers, or in deserts, and later cemented together by minerals precipitated from groundwater. Most sandstones are made up largely of quartz grains, because quartz is a very hard and chemically-resistant mineral. Ex: sandstone, limestone, shale etc. Metamorphic Rocks: Metamorphic Rocks formed from already-existing rocks that are undergoing recrystallization. Tertiary ...Geology. Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms.Marine Limestone. Marine limestone can be found in shallow water areas either 30 degrees north of or south of the equator. This includes the Indian Ocean, Caribbean Sea, Persian Gulf, Gulf of Mexico, water around the Pacific Ocean islands, and water within the Indonesian archipelago.

Limestone can be formed as a result of evaporation, as is the case for stalactites and stalagmites in caves, or through the accumulation of calcium carbonate in marine environments. Limestone is either a biological or a chemical sedimentary...Degradation of rock is the deterioration of the rock forming materials and the reduction of strength and stiffness within time. It is responsible for the failure of rock slopes and landslides as the drying and wetting cycles in long-term will extensively reduce the strength of the rock and eventually end up as a soil-like material. Weathering rate is very crucial, …Limestone caves are formed when rainwater seeps through cracks in limestone rock and dissolves it.

Cliff formation is catalyzed by various agents. The major sedimentary rocks that form a cliff are dolomite, sandstone, and limestone. Types of igneous rocks which form cliffs include granite and basalt.
Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.Chalk is a variety of limestone composed mainly of calcium carbonate derived from the shells of tiny marine animals known as foraminifera and from the calcareous remains of marine algae known as coccoliths.
