Definition
Landforms are the features of the earth that together make up the land surface. Landforms may be large such as a river terrace or floodplain; or small, such as a dune. Groups of landforms are called landscapes. Landforms are recognized by their shapes or “lay of the land,” by their positions relative to other landforms, and by the kinds of material under the landforms.
Landform TypesThree major landform types - upland, terrace, and floodplain - form a stair-step pattern in many landscapes. Rules for determining landform types are given below.

Note:
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. 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.
