NOTES- PART OF YOUR EXIT TICKET

Greenhouse Effect: Sun Heats Earth (Radiation) Heat from Earth travels back to atmosphere. Greenhouse gases trap some heat. Heats the Earth

Misconceptions; It is a good thing- natural process. (Balances Earth’s

Temp) It is not the building that houses plants.

Greenhouse Gases

Water VapourCarbon Dioxide

People/Animals exhale it. Plants absorb to live. Volcanoes produce

Methane Comes from cattle Rice Paddies

• Nitrous Oxide• Plants die

• Ozone

Enhanced Greenhouse Effect

AKA- Global Warming More on this later- but……………

CFCs Chloroflourocarbons

Aerosols Fridges Foam plastic

Small amounts- trap lots of heat!!!!

EXIT TICKET QUESTION

Explain the greenhouse effect. The following words: sun, greenhouse gases, heat, travel(s)- must be used correctly. You may use them more than once. Please underline the words.

Sun Greenhouse gases Heat Travel(s)

Bell Ringer

Put the following sentences in the correct order to explain the greenhouse effect: Greenhouse gases trap some of this radiation which

travels back to Earth. The sun’s radiation travels through the atmosphere. Infrared radiation travels back into the atmosphere. This then helps warm the Earth naturally and is

known as the greenhouse effect. Some of the sun’s radiation is absorbed and heats the

Earth.

YOU MUST WRITE THEM DOWN!

EXIT TICKET

List three things you have heard about the ozone that you feel could be true.

Know This for MASTERY QUESTION 1

The sun’s radiation travels through the atmosphere.Some of the sun’s radiation is absorbed and heats the Earth. Infrared radiation travels back into the atmosphere. Greenhouse gases trap some of this radiation which travels back to Earth. This then helps warm the Earth naturally and is known as the greenhouse effect.

Bell Ringer -Ozone

Write the number down for only the sentences that are true:1.The ozone layer is a greenhouse gas.2.It is man made.3.It protects us from UV rays from the sun.4.It is made of carbon and oxygen.5.It is made of three small oxygen atoms.6.CFCs destroy ozone.7.The largest hole in the ozone layer is at the equator.8.The largest hole in the ozone layer is at the south pole.9. The ozone layer is a layer of the atmosphere.10. Destruction of the ozone layer can disrupt the food chain.11. A well running air conditioner leaks CFCs.

Mastery Question 2:

The ozone layer is the layer of the atmosphere that protects us from the sun’s UV rays. It is made of 3 oxygen atoms, and can be destroyed by CFCs. The largest hole in the ozone is over the south pole. If we keep destroying the ozone the food chain could be affected.

Causes of Global Warming

Emissions of Greenhouse Gases: Fossil fuels (CO2)

Cars Factories Producing electricity

Methane Landfills Agriculture

• Nitrous oxide- fertilizers• CFCs• Loss of Forests
