Some Details About Lakes You By no means Knew 1

A lake is a physique of relatively nonetheless fresh or salt water of considerable size, localized in a basin, that is surrounded by land. Lakes are inland and not element of the ocean and for that reason are distinct from lagoons, and are larger and deeper than ponds. Lakes can be contrasted with rivers or streams, which are typically flowing. Even so most lakes are fed and drained by rivers and streams.

All-natural lakes are normally located in mountainous places, rift zones, and areas with ongoing glaciations. Other lakes are located in endorheic basins or along the courses of mature rivers. In some parts of the planet there are numerous lakes because of chaotic drainage patterns left more than from the last Ice Age. All lakes are short-term more than geologic time scales, as they will gradually fill in with sediments or spill out of the basin containing them.

Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric energy generation or domestic water supply, or for aesthetic or recreational purposes. The word lake comes from Middle English lake (“lake, pond, waterway”), from Old English lacu (“pond, pool, stream”), from Proto-Germanic lako (“pond, ditch, slow moving stream”), from the Proto-Indo-European root leg’ (“to leak, drain”). Cognates include Dutch laak (“lake, pond, ditch”), Middle Low German lake (“water pooled in a riverbed, puddle”), German Lache (“pool, puddle”), and Icelandic laekur (“slow flowing stream”). Also related are the English words leak and leach.

There is considerable uncertainty about defining the difference amongst lakes and ponds, and no present internationally accepted definition of either term across scientific disciplines or political boundaries exists. For example, limnologists have defined lakes as water bodies which are just a bigger version of a pond, which can have wave action on the shoreline or exactly where wind-induced turbulence plays a significant role in mixing the water column. None of these definitions completely excludes ponds and all are hard to measure. For this reason there has been growing use produced of simple size-primarily based definitions to separate ponds and lakes.

One particular definition of lake is a physique of water of two hectares (5 acres) or a lot more in region, 331 nevertheless other folks have defined lakes as water bodies of 5 hectares (12 acres) and above, or 8 hectares (20 acres) and above. Charles Elton, 1 of the founders of ecology, regarded lakes as water bodies of 40 hectares (99 acres) or a lot more. The term lake is also utilised to describe a feature such as Lake Eyre, which is a dry basin most of the time but could turn out to be filled beneath seasonal circumstances of heavy rainfall. In common usage several lakes bear names ending with the word pond, and a lesser quantity of names ending with lake are in quasi-technical truth, ponds.
