Rock formations are natural structures made up of one or more types of rocks. They can vary in size, shape, and composition, often resulting from geological processes like erosion, sedimentation, and volcanic activity. Common types of rock formations include mountains, cliffs, and caves, each showcasing unique characteristics.
These formations can provide valuable information about the Earth's history and the processes that shaped it. For example, sedimentary rock formations often contain fossils, which help scientists understand past environments and life forms. Notable examples of rock formations include the Grand Canyon and Stonehenge, both of which attract visitors and researchers alike.
