Greenhouse effect

Without the "greenhouse effect"

• Overnight temperatures would plunge downward
• the earth would catch on fire
• the earthe would heat up drastically
• the atmosphere would leave

What do greenhouse gases do?

• absorb Earth's outgoing infrared photons
• reflect Earth's incoming infrared photons
• magnify ultraviolet radiation in the atmosphere
• block the Sun's infrared radiation

True or False: All of the radiation from the Sun is absorbed by the Earth

• True
• False

Do we need greenhouse gases on Earth?

• Yes - they keep the Earth warm
• Yes - they keep all the gases on our planet
• No - they only cause terrible climate change
• No - they only block some of the Sun's rays

Which of the following is an example of how climate change could effect agriculture?

• Increased droughts could reduce the amount of water available for irrigation
• Too cold to grow certain crops
• Fewer storms - so more nice weather for planting and harvesting
• Fewer pests and weeds
