Where would you find an outcrop?

An outcrop is found where bedrock is exposed at the surface. This occurs in areas where weathering and erosion have removed the loose material, such as soil and sediment, that typically covers the bedrock. This exposure allows geologists and scientists to study the characteristics and relationships of rock layers directly and can provide valuable information about the geological history of an area.

In contrast, areas with deep sediment would not typically exhibit exposed bedrock, as the sedimentation would cover it. Underground caves are often formed in soluble rocks and provide no access to the earth's surface layer of rock. Similarly, the bottom of lakes is usually covered by water and sediment, which would inhibit any bedrock exposure. Thus, the most accurate definition of an outcrop aligns with the idea of bedrock being visible and accessible at the land's surface.
