Smoking Hills
The Smoking Hills are located on the east coast of Cape Bathurst in Canada's Northwest Territories, next to the Arctic Ocean and a small group of lakes. The cliffs were named by explorer John Franklin, who was the first European to see them on his 1826 expeditions. They contain strata of hydrocarbons (oil shales), which have been burning continuously for centuries. The fires result from autoignition of sulfur-rich lignite deposits. The clouds of smoke have given the region its name. Over time the sulfur dioxide from the smoke has acidified the shallow ponds (< area and < depth) in the dotting the area, down to a pH lower than 2. Elevated concentrations of metals (aluminium, iron, zinc, nickel, manganese and cadmium) occur in these acidic ponds. Soils and sediments have also been chemically altered. ...

Smoking Hills AXW 0129
Smoking is a practice in which a substance is burned and the resulting smoke is typically breathed in to be tasted and absorbed into the bloodstream. Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a cigarette. Smoking is primarily practised as a route of administration for recreational drug use because the combustion of the dried plant leaves vaporizes and delivers active substances into the lungs where they are rapidly absorbed into the bloodstream and reach bodily tissue. In the case of cigarette smoking, these substances are contained in a mixture of aerosol particles and gases and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas into a form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs. In some cultures, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clouds Of Smoke From Burning Sulfur-rich Lignite Deposits
In meteorology, a cloud is an aerosol consisting of a visible mass of miniature liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body or similar space. Water or various other chemicals may compose the droplets and crystals. On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point, or when it gains sufficient moisture (usually in the form of water vapor) from an adjacent source to raise the dew point to the ambient temperature. They are seen in the Earth's homosphere, which includes the troposphere, stratosphere, and mesosphere. Nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology. There are two methods of naming clouds in their respective layers of the homosphere, Latin and common name. Genus types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin names because of the universal adoption of Luke Howard's no ...
