• Yes

• No

• Both

What is the greenhouse effect?

• Sun produces solar radiation

• Some is reflected back into space by Earth's atmosphere

• Some passes through atmosphere & is absorbed by Earth's surface

• More greenhouse gases released 🢂 Greater gas layer & more thermal energy absorbed

Multiple Choice

What happens to the temperature of the atmosphere if more greenhouse gases are added? (Hint: think about Venus)

• The temperature goes up

• The temperature goes down

Multiple Choice

What happens to the temperature of the atmosphere if there were no greenhouse gases? (Hint: think about Mars)
