Rock formations are natural structures made up of solid rocks that have been shaped by various geological processes over time. These formations can vary in size, shape, and composition, often resulting from the cooling and solidification of magma, the accumulation of sediments, or the alteration of existing rocks through weathering and erosion. Common types of rock formations include mountains, cliffs, and caves. They can be found in diverse environments, from deserts to coastal areas, and often serve as important habitats for wildlife. Rock formations also provide valuable information about the Earth's history and the processes that have shaped its surface.
