Describe o Bedding – Layering o Formation – A Lithologic Unit differing from overlaying and underlying  units that can be mapped separately. o Must be 10ft thick to be mapped o Topographic map shows height, has contour lines that connects points  of equal elevation. o Dipping Sedimentary beds Strike – Direction of the Line, formed by a bedding plane and a
