9.3 The Greenhouse Effect

Required

1

They stop sunlight from getting through the atmosphere

The allow the earth to cool down by increasing the amount of snow

They trap/keep heat inside the atmosphere 

They appear green when you see them

Why is the earth getting warmer?
Extra greenhouse gases (<---CLICK THE LINK!) in our atmosphere are the main reason that Earth is getting warmer. Greenhouse gases, such as carbon dioxide (CO2) and methane, trap the Sun's heat in Earth's atmosphere.
It's normal for there to be some greenhouse gases in our atmosphere. They help keep Earth warm enough to live on. But too many greenhouse gases can cause too much warming.

Which of the following is TRUE?

It is NOT normal to have SOME greenhouse gases in the atmosphere

Greenhouse gases release heat from the atmosphere

Required

1

Why are greenhouse gases important?
Overall, greenhouse gases are a good thing. Without them, our planet would be too cold, and life as we know it would not exist. But there can be too much of a good thing. Scientists are worried that human activities are adding too much of these gases to the atmosphere.

If there were not greenhouse gases in the atmosphere, why would that be a problem?

The earth would have more plants than animals

The earth would be too hot and would burn up

The earth would get smaller

Over the last century, humans have burned coal, oil, and gasoline in our cars, trucks, planes, trains, power plants, and factories. Burning such fossil fuels, known as combustion, produces CO2 as a waste product.

What human activity is causes the biggest increase in the amount of greenhouse gases?

Combustion

Ocean Exchange/uptake

Photosynthesis

Based on the diagram above, what greenhouse gas is found in the greatest amount?

Carbon Dioxide (CO2)

Methane (CH4)

Nitrous oxide (N2O)

The graph above shows where the majority of greenhouse gases come from.

Based on this, what 2 things release the most greenhouse gases?

Agriculture & Buildings

Buildings & Transportation

Electricity & Agriculture

Required

1

The majority of greenhouse gases come from electricity. While renewable energy is rapidly growing it still only accounts for 10-15% of the total energy supply. The remaining 85-90% comes from burning fossil fuels like coal, oil, and natural gas. That's right, power plants burn fossil fuels (called combustion) to create the electricity powering your house!

Why does the creation of electricity release greenhouse gases?

The majoirty of electricity is made by lightning which causes fires, releasing carbon

The majoirty of electricity is created by using solar panels which releases carbon dioxide

Required

24% Agriculture:
Most of these emissions are from the farming of crops & livestock (cows, pigs, chickens). Irrigation practices, synthetic fertilizers, and the breakdown of nitrogen in livestock manure (poop) and urine result in the emissions of nitrous oxide (N2O). Nitrous oxide (N2O) molecules stay in the atmosphere for 114 years, and they are 300x more powerful than carbon dioxide. A third of the agriculture emissions come from methane (CH4). Livestock produce methane (CH4) as a part of their normal digestive process. Their manure (poop) adds to both nitrous oxide and methane emissions.

Which of the following is NOT true?

Emissions from farming and livestock increase greenhouse gases

As we have seen, carbon dioxide it the greenhouse gas that is being released at highest rate and in the largest amounts. What 2 processes help to remove carbon dioxide (CO2) from the atmosphere?

(Select 2 correct answers)

How does deforestation affect the amount of CO2 in the atmosphere?

Decreases CO2 due to the ocean absorbing more through ocean-atmosphere exchange

Increases CO2 due to the ocean absorbing more through ocean-atmosphere exchange

Increases CO2 due to cutting down trees and increasing photosynthesis

Required

1

How does the ocean affect the amount of CO2 in the atmosphere?

Increases CO2 due to cutting down trees and increasing photosynthesis

Decreases CO2 due to cutting down trees and decreasing photosynthesis

Decreases CO2 due to the ocean absorbing more through ocean-atmosphere exchange

Required

What does the exchange do to the oceans?

Decreases the acidity of the ocean

Increases the acidity of the atmosphere
