What are two negative effects on the carbon cycle by burning coal?
Air pollution and limited fresh air.
What are two things that pollute the air?
Cars and gas pollute the air.
What is an example of a human activity that contributes to greenhouse gases?
Two things that humans do that contribute to greenhouse gases isburn fossil fuels (coal, oil and natural gas) in transport and electricity production.Cut down forests all over the world that used to remove carbon dioxide from the air.
What is the major driving force of the oxygen cycle?
the main two processes are plant photosynthesis, which takes carbon dioxide out of the air, and plant and animal respiration which put carbon dioxide back into the air.
What two things define an air mass?
temperature and altitude
In what two main ways does deforestation alter atmospheric carbon?
Rotting timber adds either methane or carbon dioxide to the atmosphere.The missing trees no longer remove carbon from the air through photosynthesis.
Is there a difference between carbon and carbon dioxide?
Carbon dioxide is a gas that is naturally found in the air and is absorbed by plants during photosynthesis. Carbon is a nonmetallic element that can be found in two common forms: diamonds and graphite. It is also the chemical basis for all living things.
What two things that all living things need?
Carbon and Hydrogen.
What two things effect air pressure?
the two things that effect air pressure is force and area
What are two non metals found in air?
oxygen and carbon
Which gas is in the air you breathe out?
Carbon Dioxide, or CO2. Carbon Dioxide is made out of one carbon atom and two oxygen atoms.
What air pollutants combined cause carbon dioxide?
Carbon (one atom) and Oxygen (two atoms) combine to make carbon dioxide (CO2). Neither of these elements is an air pollutant, though the result, carbon dioxide, is.
Describe two things you can do to increase the acceleration of an object?
Increase the force on the objectDecrease the resistance to motion (lubricate, remove resisting stuff like the air...)
What are the two main elements in living things?
Carbon and Nitrogen
What are two ways that the burning of rainforests leads to an increase in atmospheric carbon dioxide?
The burning of rainforests releases carbon dioxide (CO2) into the atmosphere, as the combustion of anything does.When the rainforests are destroyed they no longer are able to remove CO2 from the atmosphere.Both these things lead to an increase in atmospheric carbon dioxide.
What is two things set air in motion?
they are air and pollution
What are two negative effects on the carbon cycle by burning coal?
Air pollution and limited fresh air.
