Warm-up: What happens to a car that's been sitting out in the sun on a hot summer day? Why does this happen?

Question: How do greenhouse gases affect Earth’s climate?

Examine the graphs below representing different times of the day with greenhouse gases set at 10%.

  • T (°F) represents changes in temperature measured in degrees Fahrenheit

  • Heat flow represents changes in heat going in and out of the atmosphere

Midnight

6 AM

Noon

6 PM

What do you notice about the heat flow into and out of Earth's atmosphere over the course of a day?

Heat into the atmosphere at night.

Heat out of the atmosphere

Asemmisa {{asɛmmisaAhyɛnsode}}
4.

Examine the graphs again.

Midnight

6 AM

Noon

6 PM

  • What is the highest temperature during the day?

  • What is the highest heat flow in during the day?

  • What is the heat flow out?

Asemmisa {{asɛmmisaAhyɛnsode}}
5.

Examine these graphs where the greenhouse gases have increased to 50%.

Midnight

6 AM

Noon

6 PM

How have the variables changed with the increase in greenhouse gases?

  • Heat Flow In

  • Temperature

  • Heat Flow Out

7.

The influence of greenhouse gases on temperature is called the greenhouse effect.

Based on what you have seen, how does having a higher concentration of greenhouse gases effect the earth's ability to release heat back out to space?

Use this website to learn about the major greenhouse gases (GHG). Make sure to click on the "cards" to see both sides.

Match the greenhouse gas to the correct description for the first 3 gasses.

Draggable itemarrow_right_altCorresponding Item

Methane CH4

arrow_right_alt

Blocks heat from escaping the atmosphere. Warmer air holds more of it and as Earth heats up, it traps more heat.

Water vapor H2O

arrow_right_alt

Released when burning fossil fuels

Carbon dioxide CO2

arrow_right_alt

Second most important contributor to global warming

Use this website to learn about the major greenhouse gases (GHG). Make sure to click on the "cards" to see both sides.

Match the greenhouse gas to the correct description for the last 3 gasses.

Draggable itemarrow_right_altCorresponding Item

Nitrous oxide N2O

arrow_right_alt

In the atmosphere, protects us from UV rays but acts as a GHG on the ground

Chlorofluorocarbons (CFCs)

arrow_right_alt

Released by factors, power plants, and fertilizers and damages the ozone layer

Ozone O3

arrow_right_alt

Man-made gases that damage the ozone layer

Please evaluate your performance on the learning targets

I need help

I am getting there

I got this

Learning Target 1: I can Describe how greenhouse gases warm the atmosphere

Learning Target 2: I can Identify and Describe one factor that impacts the greenhouse effect.

Learning Target 3: I can Explain the cycle of heating and cooling in the Earth's past.
