warms the air |
|
|
The convection cycle can what |
Used to move, energy, ships, and animals |
|
|
What causes prevailing winds |
Sunlight reflecting off land, warming the air then air rises, and cooler air comes to take this place. They get their direction from latitudes and earths rotation. |
|
|
What is convection? |
The circular rotation of warm air rising and cool air taking its place |

|
|
What are the four most common greenhouse gasses |
Methane, nitrous oxide, water vapor, and carbon dioxide |
|
|
What do green plants do? |
use CO2 for photosynthesis and oceans dissolve CO2 in them |
|
|
What is renewable fuel? |
Comes back within our lifetime |
|
|
How does nuclear energy work? |
nuclear reaction, fission produces heat to boil water, and make steam which spins the turbine which moves magnets past wires |
|
|
pros of nuclear energy |
-little greenhouse gasses -very efficient |
|
|
natural gas |
burn gas creates heat to boil water and makes steam with spins a turbine which moves magnets past wires |

|
pros of wind |
no greenhouse gasses renewable |
|
|
cons of wind |
not always windy kills birds noise pollution needs open windy space |
|
|
biofuel |
takes biomass(crops) and burns it to boil water to create steam which spins a turbine which moves magnets past wires |
|
|
pros of biofuel |
renewable uses waste carbon neutral |
|
|
cons of biofuel |
makes greenhouse gasses |
|
|
solar |
sunlight hits photovoltaic panels which is absorbed and turns into an electric charge and flows |
|
|
pros of solar |
renewable low maintenance no greenhouse gasses |
|
|
cons of solar |
not always sunny Limited lifespan Can’t grow crops under them Not efficient |
