El efecto invernadero (The Greenhouse Effect)

Why is the atmosphere important for life on Earth?

• It provides food for plants.

• It holds in the air we breathe and protects us from the cold.

• It creates CO2.

How does the atmosphere help keep Earth warm?

• It absorbs all the sunlight.

• It reflects heat back into space.

• It works like a blanket to keep heat from escaping.

What would the Earth's average temperature be without its "Atmospheric blanket"?

• A) 15°C (59°F)

    

   

    

•   - C) -8°C (18°F)

•  - B) 0°C (32°F)

What do plants use heat AND carbon dioxide for?

• to breathe

• to create heat

• to grow and produce oxygen

What happens to the CO2 that is NOT absorbed by plants and the ocean?

• It helps form the Earth's 'warming blanket'

• It disappears into outer space

• it turns into oxygen

What analogy is used to explain how excess CO2 affects the Earth?

• It's like wearing too many layers of clothing.

• It's like a sponge soaking up water.

• It's like a car running out of fuel.

What is the Greenhouse Effect?

• A process where plants grow faster

• A process that cools down the Earth

• A phenomenon where excess gasses trap heat in the atmosphere

What do these two graphs represent?

• the average temperature rise and oxygen levels in the atmosphere since 1880

• the average water level and CO2 levels in the atmosphere since 1880

• the average temperature rise and CO2 levels in the atmosphere since 1880

What is the relationship between CO2 levels and the temperature?

• Higher CO2 levles lead to lower temperatures.

• As CO2 levels rise, so does the Earth's temperature.

• Lower CO2 levels makes the temperature rise.
