2. According to the graph below, what wavelength of energy does the Earth
Sun's Energy & Climate
According to the graph below,
what wavelength
of energy does the Earth
receive in the greatest intensity?
visible light

3. which absorbs ultraviolet (UV)
Sun's Energy & Climate
Name the primary gas
which absorbs ultraviolet (UV)
from the sun.
ozone - O3
Found in the stratosphere

4. Name the three primary gases which absorb infrared (IR) energy
Sun's Energy & Climate
Name the three primary gases
which absorb infrared (IR) energy
carbon dioxide
methane
water vapor

5. helps prevent cancer in humans.
Sun's Energy & Climate
Why is the ozone
layer important?
It protects crops and
helps prevent cancer in humans.

6. Why is it warmer on a cloudy night than on a clear night?
Sun's Energy & Climate
Why is it warmer on a
cloudy night than
on a clear night?
Clouds (H2O vapor) absorb IR energy radiated by the Earth and trap heat.

7. Explain the greenhouse effect. Include a diagram which shows the
change in wavelength.
Apply It

10. Climate Change

11. Ice Ages

12. what triggers an ice age
Ice Ages
Ice Ages are cyclic.
The last one occurred
~12,000 years ago
The exact causes of
what triggers an ice age
are not known

13. Ice core results from the Vostok drilling site in Antarctica
Ice core results from the Vostok drilling site in Antarctica. The top plot in blue is carbon dioxide, the middle plot in red is paleotemperature, and the bottom plot in green is methane. Note how the two greenhouse gases increase with temperature

15. El Niño
A warming of the
Pacific Ocean.
Winters:
West = Stormy
South = Cold, wet
Northeast = warmer

18. A cooling of the Pacific Ocean.
La Niña
A cooling of the Pacific Ocean.
Dry in southeast. Cool, wet in northwest.
What are we now??

20. Average global temperatures are increasing. Glaciers are melting.
Global Warming
Average global temperatures
are increasing.
Glaciers are melting.
Ocean levels are rising.
Warming is natural.
Humans have helped the process
through increased levels of
carbon dioxide (CO2)
