|Geoform Type||Fault Scarp
|Definition||A relatively straight, cliff-like face or slope of considerable linear extent, which
breaks up the general continuity of the land by separating surfaces lying at different
levels (as along the margin of a plateau or mesa).
The term wall can be applied to steep or vertical areas on the seaward or exposed side of a reef. Although hard corals may be present, walls in this setting are formed by geologic processes and are not the result of reef-building activities by corals. A wall may be vertical or terraced, and is often referred to as the "drop-off."
