A Lake is a natural flowing Water Course , usually freshwater, flowing in an Sea , sea, lake Or yet another river. Sometimes a river flows into the ground and becomes sterile at the end of the course without reaching another body of water. Small rivers can be referred to using names like stream, creek, brook, rivulet, and rill. There are no official definitions to the generic word river as applied to geographic features, although in a few lands or countries that a flow is defined by its size. Many titles for small rivers are specific to geographical location; cases have been”run” in certain parts of the United States,”burn” in Scotland and northeast England, along with”beck” in northern England. On occasion a river is thought to be larger than a creek, however, not at all times: the language is vague.
Rivers are a part of the hydrological cycle; water generally accumulates at a river from precipitation through a drainage basin out of surface run off and different sources such as groundwater recharge, springs, and the release of stored water from natural ice and snowpacks (e.g., from glaciers). Potamology may be the scientific study of rivers, while limnology may be the study of arctic seas generally.
