What does ozone in the atmosphere do?

• it absorbs and traps heat energy
• it provides a place for water vapor to condense
• it protects against harmful uv radiation
• it helps plants grow

Visible light reaches Earth’s surface while infrared light is trapped as heat. Which characteristic of Earth’s atmosphere causes this to happen?

• the hole in the ozone
• the greenhouse effect
• atmospheric pressure
• the inversion layer

Which conclusion best summarizes global temperatures over the past 100 years?

• Temperatures have steadily decreased every single year

• Temperatures have generally decreased, but not for every single year

• Temperatures have steadily increased every single year

• Temperatures have generally increased, but not for every single year

• Production of methane gas in the oceans

• The melting of glaciers

• Warmer than normal ocean temperatures
