Kettle (landform)
A kettle (also known as a kettle hole, kettlehole, or pothole) is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake and when the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than deep and eventually fill with sediment. In acidic conditions, a kettle bog may form but in alkaline conditions, it will be Mire, kettle peatland. Overview Kettles ...

Puslinch Lake
Puslinch Lake is a kettle lake located in Wellington County, Ontario, Canada. It is the largest kettle lake in North America. The lake is "private", according to Puslinch Township Council, but some public access (beach and boat launch) was available near the trailer park until the owners closed both to the public in July 2020 after a snowmobile accident left the owners of the access point fiscally responsible, prompting a quick closure of the public access point. In October 2020, Township of Puslinch announced that it "working towards creating a public access to Puslinch Lake". The Puslinch Lake - Irish Creek Wetland, a provincially significant area, is adjacent to the lake. Hydrography The lake is normally fed by surface runoff and underwater springs; there are no permanent inflow streams. Several ephemeral streams discharge into Mud Bay, however. During high water conditions, the lake outflows into Puslinch Lake Creek, which is a part of the Grand River drainage basin. ...

Green Bay (Lake Michigan)
Green Bay is an arm of Lake Michigan, located along the south coast of Michigan's Upper Peninsula and the east coast of Wisconsin. It is separated from the rest of the lake by the Door Peninsula in Wisconsin, the Garden Peninsula in Michigan, and the chain of islands between them, all formed by the Niagara Escarpment. Green Bay is some long, with a width ranging from about ; it is in area. At the southern end of the bay is the city of Green Bay, Wisconsin, where the Fox River (Green Bay tributary), Fox River enters the bay. The Leo Frigo Memorial Bridge (formerly known as the Tower Drive bridge) spans the point where the bay begins and the Fox River ends, as the river flows south to north into the bay. Around mid-bay are Sturgeon Bay and the Peshtigo River. The Sturgeon Bay serves Sturgeon Bay, Wisconsin, the city named after the bay as a shortcut for large ships to use to bypass the Door Peninsula, while the Peshtigo River serves Peshtigo, Wisconsin, Peshtigo and Crivitz, Wisc ...

Kettle Moraine
Kettle Moraine is a large moraine in the state of Wisconsin, United States. It stretches from Walworth County in the south to Kewaunee County in the north. It has also been referred to as the ''Kettle Range'' and, in geological texts, as the ''Kettle Interlobate Moraine''. Background The moraine was created when the Green Bay Lobe of the Laurentide Ice Sheet, on the west, collided with the Lake Michigan Lobe of that glacier, on the east, depositing sediment. The western lobe formed Green Bay, Lake Winnebago and the Horicon Marsh. The major part of the Kettle Moraine area is considered interlobate moraine, though other types of moraine features, and other glacial features are common.https://www.uww.edu/Documents/sustainability/Part%201.pdf The moraine is dotted with kettles caused by buried glacial ice that calved off the terminus of a receding glacier and got entirely or partly buried in glacial sediment and subsequently melted. This process left depressions ranging fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kettle Pond Hossa
A kettle, sometimes called a tea kettle or teakettle, is a device specialized for boiling water, commonly with a ''lid'', ''spout'', and ''handle''. There are two main types: the ''stovetop kettle'', which uses heat from a hob, and the ''electric kettle'', which is a small kitchen appliance with an internal heating element. Etymology The word ''kettle'' originates from Old Norse ''ketill'', " cauldron". The Old English spelling was ''cetel'' with initial ''che-'' ʃlike 'cherry', Middle English (and dialectal) was ''chetel'', both come (together with German ''Kessel'' "cauldron") ultimately from Germanic ''*katilaz'', that was borrowed from Latin ''catillus'', diminutive form of ''catinus'' "deep vessel for serving or cooking food", which in various contexts is translated as "bowl", "deep dish", or "funnel". Stovetop kettles A modern stovetop kettle is a metal vessel with a flat bottom used to heat water on a stovetop or hob. They usually have a handle on top, a spout, ...

Closed Ecosystem
Closed ecological systems or contained ecological systems (CES) are ecosystems that do not rely on matter exchange with any part outside the system. The term is most often used to describe small, man-made ecosystems. Such systems can potentially serve as a life-support system or space habitats. In a closed ecological system, any waste products produced by one species must be used by at least one other species. If the purpose is to maintain a life form, such as a mouse or a human, waste products such as carbon dioxide, feces, and urine must eventually be converted into oxygen, food, and water. A closed ecological system must contain at least one autotrophic organism. While both chemotrophic and phototrophic organisms are plausible, almost all closed ecological systems to date are based on an autotroph such as green algae. Examples A closed ecological system for an entire planet is called an ecosphere. Man-made closed ecological systems which were created to sustain human l ...

Peatland
A peatland is a type of wetland whose soils consist of Soil organic matter, organic matter from decaying plants, forming layers of peat. Peatlands arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to Waterlogging (agriculture), water-logging and subsequent anoxic waters, anoxia. Peatlands are unusual landforms that derive mostly from biological rather than physical processes, and can take on characteristic shapes and surface patterning. The formation of peatlands is primarily controlled by climatic conditions such as precipitation and temperature, although terrain relief is a major factor as waterlogging occurs more easily on flatter ground and in basins. Peat formation typically initiates as a paludification of a mineral soil forests, terrestrialisation of lakes, or primary peat formation on bare soils on previously glaciated areas. A peatland that is actively forming peat is called a ''mire''. All types of mires share the common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lime (mineral)
Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities in the manufacture of steel and as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, for sugar refining, and other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous ...

Organic Matter
Organic matter, organic material or natural organic matter is the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments. It is matter composed of organic compounds that have come from the feces and remains of organisms such as plants and animals. Organic molecules can also be made by chemical reactions that do not involve life. Basic structures are created from cellulose, tannin, cutin, and lignin, along with other various proteins, lipids, and carbohydrates. Organic matter is very important in the movement of nutrients in the environment and plays a role in water retention on the surface of the planet. Formation Living organisms are composed of organic compounds. In life, they secrete or excrete organic material into their environment, shed body parts such as leaves and roots and after organisms die, their bodies are broken down by bacterial and fungal action. Larger molecules of organic matter can be formed from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acidic
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen cation, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word ''acid'' is derived from the Latin , meaning 'sour'. An aqueous solution of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
