Landforms are the features of the earth that together make up the land surface. They may be large features such as a river terrace or floodplain, or small features such as a dune. Groups of landforms are called landscapes. Landforms are recognized by their shape or “lay of the land,” by their position relative to other landforms, and by the kind of material under the landform.Landform Types
Three major landforms, upland, terrace, and floodplain, form a stair-step pattern in many landscapes. Rules for determining the landform are given below.
The parent material, as judged previously, should be used to help determine the landform.
On nearly level landscapes, official judges, where possible, will place slope stakes across nearly level surfaces to show whether they are concave or convex in shape. If the shape is not apparent, they will write Convex surface or Concave surface on the site card.
If the landform does not meet any of the guidelines above, official judges will write the name of the landform on the site card.
