4. Topography includes Elevation – height above sea level of a point on the earth’s surface Elevation – height above sea level of a point on the earth’s surface Relief – difference in elevation between the highest and lowest parts of an area. Relief – difference in elevation between the highest and lowest parts of an area. Landforms – a feature of topography (hill, valley, river, etc. Landforms – a feature of topography (hill, valley, river, etc. Topography includes Elevation – height above sea level of a point on the earth’s surface Elevation – height above sea level of a point on the earth’s surface Relief – difference in elevation between the highest and lowest parts of an area.
