Do emissions from fossil fuels in cars help the environment? Why or why not?
No, the carbon dioxide produce, traps heat, and warms the planet surface.
100
How is carbon dissolved in the ocean?
Through diffusion
100
What are living things that contain carbon called?
organisms
200
What happens to the oxygen that plants release?
It is taken in by animals who use it in cellular respiration to make ATP energy along with carbon dioxide.
200
T/F. There enough plants on earth to take care of extra carbon emitted into the atmosphere.
False, there is too much carbon in the atmosphere for plants to keep under control.
200
What process is done by consumers that makes carbon in the form of CO2?
Cellular Respiration (formula is C6H12O6+6O2 ----------> 6CO2+6H2O+36ATP)
200
T/F. Carbon is the 4th most abundant element in the universe.
True
300
When animals die they decompose to make what form of carbon?
fossil fuels.
300
Carbon is a greenhouse gas. What is a greenhouse gas?
Gases that allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere.
300
What type of fuel is in the ground after organisms decompose?
fossil fuels
300
T/F. Carbon can only be used when it is found in the ground in its liquid state, and refined to be used as fuel for cars.
False, it has many uses including cutting diamonds.
400
Carbons liquid form that is found in the ground can be refined to make what?
Gasoline for cars.
400
T/F. Carbon doesn't contribute to the melting of the glaciers.
False, carbon is one of the biggest greenhouse gasses that cause glacial melting.
400
Plants use sunlight, CO2 (carbon in its carbon dioxide form), and water to make what?
Glucose. (formula for question 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2)
400
T/F. Carbon can exist only as a gas.
False, it can exist as a solid, liquid, or gas.
500
Where does carbon released by plants, animals, decomposition bacteria, cars, and refineries go?
The atmosphere.
500
What percentage has carbon in our atmosphere gone up by since 150 years ago?
A)5%
B)10%
C)20%
D)30%
D)30%
500
T/F. Fossil fuels (Carbon in its liquid state) can be used to fuel cars straight from the ground.
False, it needs to be refined first.
500
How many gigatons of carbon are in the atmosphere?
A)620
B)720
C)759
D)826
