The earths atmosphere is dominated by which two gases?
Nitrogen (N2) - 78% Oxygen (O2) - 21%
Why do CO2 levels increase over time?
The Carbon/CO2 on earth is part of a natural cycle which balances the CO2 in the atmosphere with the carbon locked in the rocks as limestones, and hydrocarbons. In general over the totality of geologic time the amount of CO2 in the atmosphere has fallen as a result of biological processes. In recent times human activity has been responsible for releasing a large quantity of fossil Carbon (oil, gas and coal) as CO2 into the atmosphere. While much of this has been buffered by the CO2 dissolving in the oceans, there has also been a marked increase in CO2 % in the atmosphere since the industrial revolution.
Why does earths atmosphere trap energy from the sun?
The atmosphere traps energy from the sun because in our atmosphere are greenhouse gases, like carbon dioxide (CO2) and methane. These three-atom gases absorb the heat rising from the earth's surface.
How did the evolution of plants change the earth's atmosphere?
Plants take in Carbon dioxide for Photosynthesis. Thus, when the earths atmorphere was rich in Carbon Dioxide, the plants evolution caused the CO2 levels to fall and the oxygen levels to rise. (Apologies. To be correct, the 2 should be just below the O, but unfortunately, I don't know how) This made it possible for oxygen breathing animals to take to the land. (Mostly in the form of early amphibians)
What is the main regulator of CO2 in the atmosphere because CO2 desolves easily in it?
The ocean is the main regulator of CO2 in the atmosphere because CO2 dissolves easily in it.
How do humans effect earths natural cycles?
with co2 and gassed rissing into the atmosphere
How has the amount of CO2 in the atmosphere changed over the past few years?
The amount of CO2 in the atmosphere has been increasing steadily over the past few years. This increase is primarily due to human activities, such as burning fossil fuels and deforestation, which release large amounts of CO2 into the atmosphere. The rising levels of CO2 contribute to global warming and climate change.
Why is Co2 is a greenhouse gas?
because it has the ability to trap heat, thus warming the earths atmosphere :)
Would animals reduce co2 levels in the atmosphere?
No, only vegetation growing removes carbon dioxide from the atmosphere.
What greenhouse gas produced by humans activities has dramatically increased in earths atmosphere?
CO2; Carbon Dioxide
The earths atmosphere is dominated by which two gases?
Nitrogen (N2) - 78% Oxygen (O2) - 21%
What greenhouse gas used to make up most of earths early atmosphere?
Carbon dioxide, CO2
What Active volcanoes are added to the early Earths atmosphere?
There are smallamount of volcanoes. They emit so2 and co2 gases.
Does the air have more or less carbon dioxide in it?
CO2 levels in the atmosphere have been rising since the start of the Industrial Revolution. i t depends. Note that the CO2 levels of Earth's atmosphere have varied considerably over the course of its existence. For example: CO2 levels during the Cretaceous period are estimated to have been about 6 times what they are right now.
What fraction of the earths atmosphere is carbon mioxide?
Earth's atmosphere is about 0.035% CO2. Since the atmosphere is just a thin layer of gas surrounding the earth, CO2 is a much, much smaller fraction of the earth itself.
Will increased co2 levels cause climate to cool?
No, in fact, the opposite will happen. Increased carbon dioxide (CO2) levels in the atmosphere are producing an enhanced (or accelerated) greenhouse effect which is causing global warming.
Have levels of greenhouse gases changed?
The levels of CO2 have increased significantly since 1900. CO2 is not the only Greenhouse Gas, but it is the most significant in terms of volume and impact. See link for graph.
