What does an increase of carbon dioxide in the atmosphere mean?
It means there is more greenhouse gases in the air. Greenhouse gases absorb and hold the sun's heat. So an increase means that the atmosphere gets warmer, globally (global warming).
Which part of the earth acts like the glass in a greenhouse and traps heat in?
the reason is that certain gases, dubbed greenhouse gases by us scientists have the ability to trap heat radiation from the suns rays in our atmosphere, heat that would normally dissipate into the vacuum of space. those gases include methane and carbon dioxide. when in suitable amounts those gases are actually beneficial to life on earth as without them the earth would be far too cold to support any interesting life. unfortunately human activities are releasing huge amounts of said greenhouse gases into the air, meaning that more heat rays are trapped and hey presto, the world heats up
Greenhouse gases are obviously lighter than air How then are they measured by weight How does one weigh something that is lighter than air?
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air.One way to weigh something that's lighter than air is to weigh it in a vacuum.
What effect does the greenhouse effect have on light entering and leaving the atmosphere?
Greenhouse gases (water, carbon dioxide and methane, mostly) allow light to enter the earth's atmosphere. It comes in as solar radiation and about half of it is absorbed by the earth's surface. This radiation is converted to heat energy, which in turn, radiates infrared (longwave) radiation back out into space. Much of this infrared radiation is captured by the greenhouse gases in the troposphere (the lowest layer of the atmosphere). The warmed greenhouse gases then heat the air around them, and re-radiate the heat back down to earth, contributing to the greenhouse effect.
Which greenhouse gas generates from food waste?
Yes it does. Rotting garbage in a landfill gives off 40-60% mathane, with the remainder being mostly CO2. It is interesting to note that methane is a much stronger greenhouse gas than CO2 (25 times as greenhousey) if you're researching that. http://www.energyjustice.net/lfg/
What car gases are polluting the air?
CO2 or Carbon Dioxide from the gasoline being emitted from the car exhaust.
How does the greenhouse gases affect the air quality?
no
What is the concentration of greenhouse gases in the air?
The concentration of greenhouse gases in the air, largely water vapor, carbon dioxide and methane, are causing an enhanced greenhouse effect which is global warming.The amounts of greenhouse gases in the air are:5% Water Vapor0.039% CO2Trace (less then 0.001%) small amounts of other gases (methane, nitrous oxide etc)Water vapor absorbs heat like other greenhouse gases.
How is the climate affected by the greenhouse gases?
Greenhouse gases can be very hot, so once they get out into the air, the climate gets hotter.
What is the process by which gases hold heat in the air?
The greenhouse effect
What is the largest form of air pollution?
carbon/greenhouse gases
Is H20 a greenhouse gas?
No actually water is quite the opposite of a grrenhouse gas. Water acts like a giant sink that collects all the greenhouse gases in the air and buries it in the ocean. This is not very good for the fish and other animals that live in the sea becouse the gases that the water collects can poison the animals. This happens the same way that humans can get sick becouse of the dirty air. Sea animals breathe the water through their gills and the greenhouse gases that are in the water poison the animals.
What are the air pollutants that affects your atmosphere?
there are many pollutants. These are greenhouse gases.
Effect of air pollution on ozone layer depression?
Air pollution is due to greenhouse gases. These gases also cause ozone depletion.
How does atomospheric composition affect air temperature?
While the specifics of this are controversial, the generally held beliefs are that greenhouse gases cause air temperature to rise. The primary greenhouse gases in earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. For an extreme view of how greenhouse gases can affect temperature, do some research on Venus where greenhouse gases and the proximity to the sun have turned the planet into a furnace
How are people adding to greenhouse gases?
By the oil we burn it releases carbons into the air adding to the greenhouse effect and global warming.
Do greenhouse gases warm the air near earth's surface by trapping carbon dioxide?
No, greenhouse gases warm the air near the earth's surface by trapping heat from the warm earth that would otherwise escape into space.
