Other important natural sources of methane include termites (as a result of digestive processes), volcanoes, vents in the ocean floor, and methane hydrate deposits that occur along continental margins and … Other valuable chemicals derived from methane include methanol, chloroform, carbon tetrachloride, and nitromethane. Methane levels have more than doubled over the last 150 years. The most common causes of low blood potassium include Methane is an important source of hydrogen and some organic chemicals. B. Our editors will review what you’ve submitted and determine whether to revise the article. A chemical reaction between NOx and VOCs. power plants D) cement industry, which one of the following is an indicator of the quality of a research journal? How the release of methane through human activity is intensifying climate change. Sources of Methane Emissions. There are six major sources of atmospheric methane: emission from anaerobic decomposition in (1) natural wetlands; (2) paddy rice fields; (3) emission from livestock production systems (including intrinsic fermentation and animal waste); (4) biomass burning (including forest fires, charcoal combustion, and firewood burning); (5) anaerobic decomposition of organic waste in … During the last 800,000 years, methane concentrations have alwa… Other human activities that are associated with methane production include biomass burning, livestock farming, and waste management (where bacteria produce methane as they decompose sludge in waste-treatment facilities and decaying matter in landfills). starting point for further investigations. Which of the following is a source of methane? power plants D) cement industry. A) impact (Plain bonds represent bonds in the plane of the image; wedge and dashed bonds represent those directed toward and away from the viewer, respectively.). Let us know if you have suggestions to improve this article (requires login). The incorrect statement is: a scientific hypothesis is a scientific theory. Of these…. This conversation has been flagged as incorrect. Methane is produced by the breakdown or decay of organic material and can be introduced into the atmosphere by either natural processes – such as the decay of plant material in wetlands, the seepage of gas from underground deposits or the digestion of food by cattle – or human activities – such as oil and gas production, rice farming or waste management. factor B) h-index C) g- index D) i10-index, which of the following is a source of methene? Refrigerants/coolants. User: What ... Weegy: The elements of health, physical, mental/emotional/spiritual, and social are interconnected and should be kept ... Weegy: A galaxy that has a shape similar to a football is an irregular galaxy. Consider the following about Coastal Regulation Zone Notification, 2011. The incomplete combustion of methane yields carbon black, which is widely used as a reinforcing agent in rubber used for automobile tires. Explosions of such mixtures have been frequent in coal mines and collieries and have been the cause of many mine disasters. Save 50% off a Britannica Premium subscription and gain access to exclusive content. proposed explanation for a phenomenon. Methane that is produced and released into the atmosphere is taken up by methane sinks, which include soil and the process of methane oxidation in the troposphere (the lowest atmospheric region). WINDOWPANE is the live-streaming social network that turns your phone into a live broadcast camera for streaming to friends, family, followers, or everyone. Omissions? (d) scientific hypothesis is a scientific theory. A) wetland B) foam industry C) thermal Methane, colourless, odourless gas that occurs abundantly in nature and as a product of certain human activities. is made on the basis of limited evidence as a Black Friday Sale! Share what’s outside your window and all around you. By 2020 atmospheric methane had reached 1873.5 ppb, some two to three times higher than preindustrial levels, which hovered at 600–700 ppb. The production and combustion of natural gas and coal are the major anthropogenic (human-associated) sources of methane. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. Which has increased global methane levels. Increased concentrations of methane in the atmosphere contribute to the greenhouse effect, whereby greenhouse gases (particularly carbon dioxide, methane, and water vapour) absorb infrared radiation (net heat energy) and reradiate it back to Earth’s surface, potentially trapping heat and producing substantial changes in climate. Anthropogenic methane production, however, can cause methane concentrations to increase more quickly than they are offset by sinks. ... Weegy: A user can easily move to the end of a document by pressing the Identify the incorrect statement : (a) a hypothesis is made on the basis of limited evidence as a starting point for further investigations. Methane also is the chief constituent of natural gas, which contains from 50 to 90 percent methane (depending on the source), and occurs as a component of firedamp (flammable gas) along coal seams.
