Other forms: outcropping; outcrops; outcropped
An outcrop is an area of land where the underlying rocks are exposed. You can see many rocky outcrops throughout Shenandoah National Park in Virginia.
The term outcrop and the alternative outcropping come from the "head or sprout" meaning of crop, from the idea of seeing the "head" of the rock below. Most of the earth's land surface is covered with soil and plants, but in areas where erosion has worn these away, you can see outcrops of the bedrock beneath. These outcrops can be low, flat sheets of rock, or taller rocky expanses along the edges of mountain ridges.
