QUESTION:
 What are some special problems with an oil spill on a
rocky coast?
 What is a possible strategy for clean-up?
ANSWER:
 The oil could sink between the rocks making it
harder to clean up. Rocky coastlines are often hard to
get to, hindering cleanup efforts.
 Absorbent pads.

Climate Change and Oil in the Arctic
300 Points
QUESTION:
 Explain the albedo effect.
ANSWER:
 Light surfaces such as snow and ice reflect more sunlight,
while dark surfaces like open water absorb sunlight. As the
ocean absorbs more heat, it warms up, causing more ice to
melt, which means there is more surface area where sunlight is
being absorbed.

QUESTION:
 How does retreating sea ice affect black guillemots?
ANSWER:
 As sea ice retreats farther from land, guillemots have
to travel greater distances to feed their chicks, so
they can’t bring as much food back. At some point,
they won’t be able to get enough food to keep their
chicks alive and will have to find another food source

QUESTION:
 Name two reasons why an oil spill in the Arctic could
be particularly devastating.
ANSWER:
 Environmentally sensitive region, top predators
congregate, food web dependent on plankton
blooms, short productive season
