Image:Ribbon Lake.JPG|'''[[Ribbon lake]]''' is a long and narrow, finger-shaped '''[[lake]]''', usually found in a glacial trough. Its formation begins when a '''[[glacier]]''' moves over an area containing alternate bands of hard and soft bedrock. The sharp-edged '''[[boulders]]''' that are picked up by the glacier and carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. On either side of the rock basin, the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars, which act as dams between which rainwater may accumulate after the retreat of the ice age, filling up the rock basin and creating a ribbon lake.

The Earth's outer solid layer, the '''[[lithosphere]]''', is made of rock. In general rocks are of three types, namely, '''[[igneous]]''', '''[[sedimentary]]''', and '''[[metamorphic]]'''. The scientific study of rocks is called petrology, and petrology is an essential component of geology.

The term is roughly analogous to "drainage basin", and are often used either interchangeably. While primarily describing the geologic/geographic drainage patterns of water, a more holistic view of the word watershed incorporates all the biotic and abiotic communities and processes contained in the drainage basin.

Current revision

Landform or physical feature comprises a geomorphological unit, and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such, is typically an element of topography.

Landform elements also include seascape and oceanic waterbody interface features such as bays, peninsulas, seas and so forth, including sub-aqueous terrain features such as submersed mountain ranges, volcanoes, and the great ocean basins.
