Innuitian Mountains
The Innuitian Mountains are a mountain range in Nunavut and the Northwest Territories, Canada. They are part of the Arctic Cordillera and are largely unexplored, due to the hostile climate. They are named after the northern indigenous people, the Inuit. In some locations the Innuitian Mountains measure over in height, and in length. The highest point is Barbeau Peak on Ellesmere Island at . There are no trees and minimal wildlife in the Innuitian Mountains due to the harsh cold climate as well as being located north of the Arctic tree line. This region is mostly barren with vast areas of permafrost. There are metallic mineral resources including iron and zinc and fossil fuel resources such as coal. The Innuitian Mountains consist of numerous smaller mountain ranges. Some of these are the British Empire Range, the Princess Margaret Range and the United States Range, which is the world's second most Northern mountain range after the Challenger Mountains.

Mineral Resource
Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife. Natural resources is a part of humanity's natural heritage or protected in nature reserves. Particular areas (such as the rainforest in Fatu-Hiva) often feature biodiversity and geodiversity in their ecosystems. Natural resources may be classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, air, as well as any living organism such as a fish, or it may be transformed by extractivist i ...

Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and dis ...

Igneous Rock
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American Plate
The North American Plate is a tectonic plate covering most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. With an area of , it is the Earth's second largest tectonic plate, behind the Pacific Plate (which borders the plate to the west). It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, which are accreted to the craton by tectonic actions over a long span of time. It is thought that much of North America west of the Rocky Mountains is composed of such terranes. Boundaries The southern boundary with the Cocos Plate to the west and the Caribbean Plate to the east is a transform fault, represented by the Swan Islands Transform F ...

Lake Hazen
Lake Hazen is a freshwater lake in the northern part of Ellesmere Island, Nunavut, Canada, north of the Arctic Circle. It is the largest lake north of the Arctic Circle by volume. By surface area it is third largest, after Lake Taymyr in Russia and Lake Inari in Finland. The area around the lake is a thermal oasis within a polar desert, with summer temperatures up to . The lake itself is covered by ice about ten months a year. It is fed by glaciers (most importantly Henrietta Nesmith and the Gilmour Glaciers) from the surrounding Eureka Uplands—Palaeozoic rocks north of the lake, rising up to above sea level—and drained by long Ruggles River, which flows into Chandler Fjord on the northern east coast of Ellesmere Land. The lake is flanked by the Arctic Cordillera. The lake is long and up to wide, with an area of .Mark Nuttal: ''Encyclopedia of the Artctic''.

Adolphus Greely
Adolphus Washington Greely (March 27, 1844 – October 20, 1935) was a United States Army officer and polar explorer. He attained the rank of major general and was a recipient of the Medal of Honor. A native of Newburyport, Massachusetts and an 1860 graduate of Brown High School (now Newburyport High School), in 1861 he enlisted in the Union Army for the American Civil War. He received his commission as a second lieutenant in 1863 and was promoted to first lieutenant in 1864 and captain in 1865. At the end of the war he received a brevet promotion to major in recognition of his wartime accomplishments. After the war, Greely accepted a second lieutenant's commission in the regular army. In 1881, he was appointed to command the Lady Franklin Bay Expedition, a 25-man expedition organized to carry out Arctic explorations. The expedition ran short of food and several resupply and rescue missions were unsuccessful, and by the time Greely and his men were rescued in 1884, there ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
