Lecture 25

Question 1

Describe the greenhouse effect

Answer 1

Traps heat in the atmosphere

Question 2

What are two gasses that are invisible to infrared radiation?

Answer 2

O2 and N2

Question 3

What are three gasses that trap heat in the atmosphere

Answer 3

CO2, CH4 and N2O

Question 4

Why is the moon freezing if its the same relative distance from the sun as earth is?

Answer 4

Because the moons atmosphere doesn’t have CO2, CH4 and N2O to trap heat

Question 5

What happens if we increase a greenhouse gas’s concentration?

Answer 5

It will deepen the troughs

Question 6

The further the actual is from the black body line the more heat energy is in the atmosphere. what is this called

Question 12

Define Climate change

Answer 12
