Why is the earth experiencing the Greenhouse effect?
When fossil fuels are used, the release carbon dioxide. The carbon dioxide is trapped in the Earth's atmosphere and that causes the Earth to get hotter.
What describes seasonal changes in the levels of carbon dixode in the atmosphere?
Seasonal changes in carbon dioxide levels are driven by the Earth's natural processes. During the winter, plants go dormant and release less oxygen during photosynthesis, causing carbon dioxide levels to rise. In the spring and summer, plants become active and absorb more carbon dioxide, leading to a decrease in atmospheric levels.
Why have carbon dioxide levels in the earth fallen?
Carbon dioxide levels have not fallen. They have been gradually increasing for the past 250 years when man began burning fossil fuels and cutting down trees. Since 1980 CO2 levels have increased more rapidly than ever before.
Why are atmospheric carbon dioxide levels increasing while total carbon levels remain constant?
Atmospheric carbon dioxide levels are increasing because human activities, such as burning fossil fuels, release more carbon dioxide into the atmosphere than natural processes can remove. This imbalance leads to a buildup of carbon dioxide in the atmosphere, even though the total amount of carbon on Earth remains relatively constant.
Why does the level of carbon dioxide affect the global temperature?
Carbon dioxide (and other gases) creates a "blanket" around the earth trapping heat in the atmosphere. If these "greenhouse" gases were not there some of the heat would escape from the earth's atmosphere --------------------------------------------------------------------------------------- Carbon dioxide is transparent to visible light but opaque to infrared light (i.e. heat). When sunlight passes through the atmosphere and heats the surface of the earth the earth radiates infrared light. At low levels of carbon dioxide most of this infrared escapes to space, cooling the earth; but at high levels of carbon dioxide most of this infrared is reflected back down to the surface of the earth, keeping it hot.
What happens when the atmosphere has a higher percentage of carbon dioxide and lower oxygen?
The Earth will become hotter as carbon dioxide traps heat to keep the Earth warm. But too much carbon dioxide will cause the Earth to be more warm and that lead to global warming.
Starting billions of years ago algae lowered the levels in the atmosphere?
Carbon Dioxide
What name is given to warming of the earth due to increased levels of carbon dioxide?
The name given to warming of the earth due to increased levels of carbon dioxide is global warming. This is a result of the greenhouse effect, where carbon dioxide and other greenhouse gases trap heat in the Earth's atmosphere, leading to a rise in temperature.
Why is the earth experiencing the Greenhouse effect?
When fossil fuels are used, the release carbon dioxide. The carbon dioxide is trapped in the Earth's atmosphere and that causes the Earth to get hotter.
What is happening today that proves global warming is happening?
Sea levels are rising because warm water expands, and also from melted glaciers. The earth is becoming hotter because of the extra greenhouse gases. Satellites are measuring reduced radiation from the earth in the infrared wavebands that warm carbon dioxide (meaning that carbon dioxide is trapping the heat rising from the earth).
Which planet has a thick atmosphere which is mainly composed of carbon dioxide?
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth.

How long ago did the atmosphere on earth have the most carbon dioxide?
The atmosphere on Earth had the most carbon dioxide around 300 million years ago during the Carboniferous period. This period is known for high levels of atmospheric carbon dioxide which supported the growth of lush forests and high oxygen levels.
Carbon dioxide in a sentence?
Carbon dioxide is a colorless gas that is naturally present in Earth's atmosphere and is produced by burning fossil fuels and other human activities, contributing to global warming and climate change.
