Hydrocarbons
Carbon Cycle and Greenhouse Effect
100
Name two things that nitrogen helps plants to make.
What are proteins and amino acids?
100
This man designed the process by which nitrogen from the air bonds with hydrogen to make ammonia. He was a Nobel Prize winner.
Who is Haber?
100
This law says that mass cannot be created or destroyed
What is the Law of Conservation of Mass?
100
These two elements make up hydrocarbons
What are hydrogen and carbon?
100
This is the first process that occurs during the carbon cycle. You may remember it's how green plants use the sunlight to get food.
What is photosynthesis?
200
Nitrogen is this percentage of air
What is 78%?
200
This Nobel Prize winner's invention of artificial fertilizer had what effect on the world's population?
What is increased the world population?
200
This happens to carbon molecules in gas and coal, according to the Law of Conservation of Mass.
What is recycled into the atmosphere as CO2?
200
These organisms from millions of years ago are the source of oil in hydrocarbons.
What are phytoplankton?
200
These gases in the atmosphere absorb and give off energy. They create this type of effect.
What are greenhouse gases?
300
This condition of nitrogen makes it hard for nitrogen molecules to break
What is the triple bond?
300
This is the name of the process that happens when too many nitrogen compounds run off soil and into the waterways and oceans.
What is eutrophication?
300
Carbon forms this number of bonds and is the basic element of all life.
What are 4?
300
Plants found in the swamp during the Carboniferous period are the source of this fossil fuel.
What is coal?
300
The Greenhouse effect occurs when CO2 and other gases in the atmosphere trap heat, which does this to the earth
What is keeps it warm?
400
These organisms can break nitrogen's triple bond, converting it into ammonia, nitrate, and nitrite.
What is bacteria in the soil?
400
Algae and cyanobacteria populate in the waterways and the oceans when there is too much of this used on the land.
What is fertilizer?
400
Organic compounds are all made up of these two elements
What are carbon and hydrogen?
400
When you fill up your car with fuel, you are using this type of hydrocarbon.
What is gasoline?
400
These four processes in the carbon cycle occur because of carbon dioxide in the air.
What are photosynthesis, respiration, decomposition, and combustion?
500
In the nitrogen cycle, these convert atmospheric nitrogen to ammonia, nitrates, and nitrites.
What are prokaryotes?
500
When a dead zone occurs in the water, such in the Gulf off the coast of Louisiana, there is a low amount of this.
What is oxygen or O2?
500
Carbohydrates are made up of these three elements
What are carbon, hydrogen, and oxygen?
500
Hydrocarbons include these fuels and gases--don't forget to say, "Excuse me!"
What are methane, propane, octane (gasoline), and oil products?
500
During this step of the carbon cycle, glucose, starch, proteins, and fats go back to being CO2
What is decomposition?
