Humans have greatly increased the level of what in the atmosphere?
carbon dioxide
What temperature decreases in the third layer of the atmosphere?
celsius
Why does refrigeration produce cfcs?
Refrigerators do not produce CFC. Old equipment contains these materials as they were the refrigerant of choice before the Montreal Protocol. The old equipment lost the CFCs to the atmosphere due to leaks and gasket failure.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
What layer of the atmosphere is most affected by fluorocarbons?
The ozone layer, which is part of the stratosphere, is the most affected by fluorocarbons. When chlorofluorocarbons or CFCs are released into the atmosphere, they migrate from the troposphere to the stratosphere after about 3 to 5 years. These CFCs destroy the ozone layer.
Why does the air pressure change the altitude in the atmosphere?
As the amount of air above us decreases...the air pressure decreases.
What substitutes for CFCs came into being after scientists discovered that CFCs were harming the atmosphere?
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
How are cfcs released?
CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.
The amount of gas in the atmosphere does what when the height above the earth's surface increases?
It decreases
Which process increases the amount of oxygen and decreases the amount of carbon dioxide in the atmosphere?
Photosynthesis by green vegetation and forests.
What is the protective layer of the atmosphere destroyed by CFCs?
ozone
What kind of effect do CFCs - chlorofluorocarbons - have on the atmosphere?
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
How do human activities contribute CFC's to the atmosphere?
humans use products containing CFCs which accumulate in the atmosphere.
Humans have greatly increased the level of what in the atmosphere?
carbon dioxide
How do you CFCs illustrate that technical knowledge can be a double edged sword?
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
How are cfcs in the upper atmosphere related to the ozone layer?
They are carried by westerlies. They destroy the ozone.
What is the strongest evidence that cfcs are in the stratosphere?
Satellite measurements of light passing through the atmosphere
