Exorheic
Open and closed lakes refer to the major subdivisions of lakes – bodies of water surrounded by land. Exorheic, or open, lakes drain into a river or other body of water that ultimately drains into the ocean. Endorheic basins fall into the category of endorheic or closed lakes, wherein waters do not drain into the ocean, but are reduced by evaporation, and/or drain into the ground. Open lake An open lake is a lake where water constantly flows out under almost all climatic circumstances. Because water does not remain in an open lake for any length of time, dissolved solids do not accumulate, and such lakes are usually fresh water. Open lakes form in areas where precipitation is greater than evaporation. Because most of the world's water is found in areas of highly effective rainfall, most lakes are open lakes whose water eventually reaches the sea. For instance, the Great Lakes' water flows into the St. Lawrence River and eventually the Atlantic Ocean. Open lakes typicall ...

Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of ocean ...

Red River Of The North
The Red River (), also called the Red River of the North () to differentiate it from the Red River of the South, Red River in the south of the continent, is a river in the north-central United States and central Canada. Originating at the confluence of the Bois de Sioux River, Bois de Sioux and Otter Tail River, Otter Tail rivers between the U.S. states of Minnesota and North Dakota, it flows northward through the Red River Valley, forming most of the border of Minnesota and North Dakota and continuing into Manitoba. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into Hudson Bay. The Red River is about long, of which about are in the United States and about are in Canada.Red River Map 3 Minnesota DNR; map shows the international border at river mile 155.

Stump Lake, North Dakota
Stump Lake is a naturally formed lake located in Nelson County, North Dakota. It covers , has of shoreline, and has an average depth of with a maximum depth of . It is stocked by the North Dakota Department of Natural Resources with Walleye, Yellow Perch, and Northern Pike. Stump Lake's waters have risen in the last few years, and are now at the levels of neighboring Devils Lake. Devil's Lake will overflow into Stump Lake if the surface level reaches . Stump Lake, like Devil's Lake, is an endorheic (closed) lake, and has no input or output of rivers or streams, and is only fed by rain or human sources. If water levels exceed the combined lake would flow into the Sheyenne River. This has not occurred since lake levels in this area have been recorded. Stump Lake Park is found around the lake and is solely dedicated to it. Local Native Americans have referred to the lake as "Chicot" which translates as "a place of stumps". The Stump Lake Park is the location of the Old S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Medieval Warm Period
The Medieval Warm Period (MWP), also known as the Medieval Climate Optimum or the Medieval Climatic Anomaly, was a time of warm climate in the North Atlantic region that lasted from about to about . Climate proxy records show peak warmth occurred at different times for different regions, which indicate that the MWP was not a globally uniform event. Some refer to the MWP as the ''Medieval Climatic Anomaly'' to emphasize that climatic effects other than temperature were also important. The MWP was followed by a regionally cooler period in the North Atlantic and elsewhere, which is sometimes called the Little Ice Age (LIA). Possible causes of the MWP include increased solar activity, decreased volcanic activity, and changes in ocean circulation. Modelling evidence has shown that natural variability is insufficient on its own to explain the MWP and that an external forcing had to be one of the causes. Research The MWP is generally thought to have occurred from about to about , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devils Lake (North Dakota)
Devils Lake is a lake in the U.S. state of North Dakota. It is the largest natural body of water and the second-largest body of water in North Dakota after Lake Sakakawea. It can reach a level of before naturally flowing into the Sheyenne River via the Tolna Coulee. On June 27, 2011, it reached an unofficial historical high elevation of . The cities of Devils Lake and Minnewaukan take their name from the lake as does the Spirit Lake Reservation, which is located on the lake's southern shores. History The present site of Devils Lake is historically territory of the Dakota people. The Sisseton, Wahpeton, and Cut-Head bands of Dakotas were relocated to the Spirit Lake Reservation as a result of the 1867 treaty with the United States that established a reservation for Dakotas who had not been forcibly relocated to Crow Creek Reservation in what is now called South Dakota. The name "Devils Lake" is a calque of the Dakota words ''mni'' (water) ''wak'áŋ'' (literally "pure sour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 is a well-documented effects of climate change, effect of climate change. The retreat of Mountain glacier, mountain glaciers provides evidence for the Instrumental temperature record, rise in global temperatures since the late 19th century. Examples include mountain glaciers in western North America, Asia, Alps, the Alps in central Europe, and tropical and subtropical regions of South America and Africa. Since glacial mass is affected by long-term climatic changes, e.g. Precipitation (meteorology), precipitation, Temperature, mean temperature, and cloud cover, glacial mass changes are one of the most sensitive indicators of climate change. The retreat of glaciers is also a major reason for sea level rise. Excluding peripheral glaciers of Ice sheet, ice sheets, the total cumulated global glacial losses over the 26 years from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per year.Fox-Kemper, B., H.T.
