A geological cross-section adds a view of the rocks beneath it, as though the ground had been sliced vertically. Its upper line represents the land surface; patterns or colours below it represent different rocks, identified by a key. Lines separating those patterns are rock boundaries, not necessarily valleys or cracks.
