If 70% of the energy from the sun that hits Earth is absorbed, how much will eventually leave?
70%
100
What happens to the 70% of the sun's energy that hits Earth before it leaves?
It is absorbed by clouds, water, land and people and used
100
What is the most common greenhouse gas?
Carbon dioxide, CO2
100
What is Deforestation?
Act of cutting down forest to harvest wood.
200
Give me two examples of Radiation?
Sunlight, campfire, x ray machines, radio waves from a broadcast,
200
What would happen to the Earth if the amount of sunlight reflected was increases?
Potential cooling, more ice, lower global temperatures.
200
Why must carbon be recycled?
Carbon is in limited supply. Its a finite resource.
200
What happens when we refine petroleum into gas, diesel, fuel oil, etc.?
Releases large amounts of methane which is a greenhouse gas.
300
Give me two examples of Convection.
Water boiling in a pot, hot air rising from a fire, a hot air balloon, sea breezes, wind patterns. Heat rising in a room.
300
What would happen if the amount of sunlight absorbed is increased?
Increased global temperatures, polar ice caps would melt.
300
Is it possible for Carbon dioxide levels to go down even with human population ever growing?
Yes, we saw during Covid, for the first time ever, average carbon dioxide levels fell worldwide.
300
What is the problem with raising larger and larger amounts of cattle (cows)?
Cows release methane when they toot.
400
Give me two examples of Conduction.
Heat moving through the handle of a pan, burning you hand on a hot stove, metal spoon getting hot when you place it in hot liquids.
400
What is the relationship between carbon dioxide levels and average global temperatures?
The more CO2, the higher average global temperatures.
400
When did Carbon Dioxide levels begin to drastically increase?
Industrial Revolution.
400
What are two problems with Deforestation in relation to greenhouse gasses?
Older bigger trees absorb much larger amounts of carbon dioxide.
Burning fire wood releases large amounts of carbon dioxide.
Deforestation is done to produce farmland. Farm animals like cows release large amounts of methane.
500
How can we prove their is internal Earth energy?
Tectonic plate activity, molten lava rock rising to the surface.
As we go deeper into the crust, it gets hotter and hotter.
500
Come up to the board and draw the normal greenhouse effect and then what happens when the amount of greenhouse gasses is increased.

Fill in the four missing boxes in the Carbon Cycle chart.
Teacher approval

What is the problem with water, in relation to greenhouse gasses, as average global temperatures increase.
Water vapor is a greenhouse gas. ~73% of Earth is covered in water. Average global temperatures causes even more water to evaporate into water vapor creating even more of a greenhouse gas effect.
