Projecting Rock is a geological term used to describe a type of rock formation that protrudes from the surface of the ground. The two most common types of projecting rock are crags and scars. Crags are steep, rocky cliffs that are often found in mountainous regions. Scars are large, jagged rocks that are usually found in areas with a lot of erosion. Both crags and scars are formed by the same process, which is the result of weathering and erosion.
