Greenhouse Gas Effect

Question 1

What are 3 common greenhouse gases?

Answer 1

Water vapour.
Carbon dioxide.
Methane.

Question 2

How do greenhouse gases make the Earth warmer?

Answer 2

They absorb heat radiated from the Earth.
Then release energy in all directions.

Question 3

Energy from the sun travels to the Earth as what type of radiation?

Answer 3

Short wavelength radiation.

Question 4

What type of short wavelength radiation mainly passes through the Earth’s atmosphere?

Answer 4

Electromagnetic radiation.

Question 5

Some of the short wavelength radiation ___________ but most ___________________ the Earth’s ____________________.

Answer 5

deflects
passes through
atmosphere

Question 6

Why does short wavelength radiation mostly pass through the atmosphere?

Answer 6

Because short wavelength radiation does not react strongly with gas molecules in the atmosphere.

Question 7

Answer 7

short wavelength radiation
surface

Question 8

The Earth’s surface now radiates the short wavelength radiation energy as _____________________ (such as ___________).

Answer 8

long wavelength radiation
infrared

Question 9
