A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. [2] Most are naturally occurring geographical features, but some are artificial. There are types that can be either.
Sound – A long, relatively wide body of water, connecting two larger bodies of water; Spit – Coastal bar or beach landform deposited by longshore drift; Spring – A point at which water emenges from an aquifer to the surface; Stack – Geological landform consisting of a steep and often vertical column or columns of rock and stump
Block: Water descends from a relatively wide stream or river. [1] [2] Cascade: Water descends a series of rock steps. [1] [2] Segmented: Distinctly separate flows of water form as it descends. [1] Tiered: Water drops in a series of distinct steps or falls. [1] Punchbowl: Water descends in a constricted form and then spreads out in a wider pool. [1]
The earliest life forms appeared in water; nearly all fish live exclusively in water, and there are many types of marine mammals, such as dolphins and whales. Some kinds of animals, such as amphibians , spend portions of their lives in water and portions on land.
Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of water scarcity. One is physical. The other is economic water scarcity. [33]: 560 Physical water scarcity is where there is not enough water to meet all demands.
There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time). Limnology (and its branch freshwater biology) is a study about freshwater ...
