Greenhouse Gases
What do greenhouse gases do in the atmosphere?
Trap heat in the atmosphere.
How do cars affect the atmosphere?
They release carbon dioxide when they burn gasoline.
What is global warming?
The gradual increase in Earth’s average temperature
What does a capital “T” represent in a Punnett square?
A dominant trait (tall).
What is the first step in the water cycle?
Evaporation.
Name two greenhouse gases.
Carbon dioxide and methane.
What happens when forests are cut down?
Less carbon dioxide is absorbed, increasing greenhouse gases.
What causes global warming?
Increased greenhouse gases in the atmosphere.
What does “Tt” mean in genetics?
One dominant and one recessive gene — heterozygous.
What forms after evaporation?
Condensation.
Where do greenhouse gases come from?
Burning fossil fuels, farming, and factories.
How does electricity use impact the atmosphere?
Most electricity comes from burning fossil fuels, releasing gases
Name one effect of global warming on the oceans.
Rising sea levels.
What is the result of crossing Tt x Tt in a Punnett square?
1 TT, 2 Tt, 1 tt.
What do clouds produce in the water cycle?
Precipitation.
Why is methane a dangerous greenhouse gas?
It traps much more heat than carbon dioxide.
What is one way humans create pollution?
Through industrial processes like factory emissions.
How does global warming affect the weather
It can cause more heat waves and stronger storms.
What percentage of offspring will be tall if “T” is tall and “t” is short?
75% will be tall (TT or Tt).
What happens after precipitation?
Runoff and collection.
What is the connection between permafrost and greenhouse gases?
Melting permafrost releases methane, accelerating global warming.
Name three ways humans negatively affect the atmosphere.
Driving cars, using electricity, cutting down forests.
What is one way to reduce global warming?
Use renewable energy or plant trees.
What is the probability of getting “tt” from Tt x Tt?
25%
Name all 5 main steps of the water cycle.
Evaporation, condensation, precipitation, runoff, collection.
