Climate

What is the primary function of the greenhouse effect?

• To insulate our planet from the cold of outer space

• To increase the amount of carbon dioxide in the atmosphere

• To decrease Earth's temperature

• To prevent sunlight from entering Earth's atmosphere

Which gases are responsible for trapping the sun's energy in our atmosphere?

• Oxygen and Nitrogen

• Carbon dioxide and water vapor

• Helium and Hydrogen

• Argon and Neon

What has been the effect of human activities on the atmosphere?

• Increase in the amount of oxygen in the atmosphere

• Change in the composition of the atmosphere

• Reduction in the Earth's overall temperature

• Decrease in the amount of solar energy reaching Earth

By what percentage has the amount of carbon dioxide in the atmosphere increased over the last 100 years?

• 25%

• 15%

• 10%

• 30%

What are the three main climate zones on Earth?

• Mountainous, Coastal, Flatland

• Continental, Oceanic, Mediterranean

• Polar, Temperate, Tropical

• Desert, Rainforest, Tundra

Where are polar zones located?

• Around the equator

• At the highest mountain peaks

• Around the North and South poles

• In the center of large continents

Which zone receives direct or nearly direct sunlight all year long?

• Temperate zone

• Tropical zone

• Polar zone

• None of the above

Green House gases

• absorb the sun's radiation and trap heat

• are good for our health

• absorb gravity and keep us attached to Earth

• expulse radiation to the sun and prevent us from getting to warm

Without the Greenhouse Effect the Earth would be

• warm 
• cold
• dead

What is climate?

• weather

• rain, sleet, snow, or hail

• average weather in a region over a long period of time

• the amount of ice cream available in a city
