Paper 1, Paper 2, Paper 3
A line joining points at the same height above sea level.
Revise: Specialised Cartographic Skills: Isolines, Choropleths and Flow LinesContours join points of equal height above sea level; isotherms join points of equal temperature; isobars join points of equal atmospheric pressure.
Specification 1.6, 1.10 · Paper 1
Identify a landform using a combination of channel shape, contours and labels, rather than its likely position in the river’s course alone.
Use the map’s key and stated contour interval. Widely spaced contours indicate gentle slopes, not necessarily low altitude.
Support a landscape description with map evidence, such as named features, heights, contour spacing or the arrangement of settlements.

A line on a map joining places of equal height above mean sea level.
Combine that symbol with relief evidence: contours close together indicate a steep slope, whereas widely spaced contours indicate a gentler slope. Explorer contours have 5 m and/or 10 m vertical intervals, so check the interval on the particular map. Heights are measured above mean sea level.

Paper 2
A line on a map joining points at the same height above sea level.
Revise: Map Skills: Locating and Identifying UK FeaturesA contour joins places at the same height above sea level. Its numerical label gives that height in metres. A spot height gives the height of one particular point rather than a whole line.

A line on a map joining points of equal height.
Revise: Fundamental OS Map Skills: Scale, Coordinates and ReliefA contour line joins points of equal height, so every location along a contour labelled 100 m has that height.
