Characteristics & Importance
Where the poles are located
What is: northern and southernmost points on Earth (66.5 degrees N or S and higher)?
The amount of radiation that's reflected off a surface
What is albedo?
Which pole you'd find penguins
What is Antarctica (South)?
Name 1 adaptation to having to walk on ice **200 points if you name 2 adaptations**
What is: large feet, long claws/nails?
Name one way climate change is affecting the poles
What is: spp distribution, warmer temperatures, ice melting/thinner, sea level rise?
3 climate characteristics of poles
What is: long cold winters, below freezing year round, windy, minimal precipitation, permanent ice caps?
What productivity really means
What is: how much photosynthesis is occurring?
Which pole you'd find polar bears
What is Arctic (North)?
One way organisms camouflage to hide from predators or prey
What is: light coloration, countershading?
Why having more shipping activity at the poles is bad
What is: more activity = more pollution (noise, chemical) = disturbs and runs away wildlife?
3 ways poles are important
What is: shipping pathways, food, keep Earth's climate balanced, ocean current circulation?
Ice at the poles has a (higher/lower) albedo compared to the ocean's surface at the equator
What is higher?
How fish avoid freezing in water at the poles
What are anti-freeze proteins?
3 ways organisms have adapted to the cold polar environments
What is: migrate, thick blubber, small SA:V, small limbs, dense fur, oily fur/feathers, anti-freeze proteins?
Why having flat ice is bad for many organisms
What is: predators and prey can't hide?
How the poles keep Earth's climate balanced
What is: sea ice has high albedo, cools warm water and allows cool water to be redistributed to warm parts of Earth?
What is summer?
Which pole you'd find narwhals
What is Arctic (North)?
How having dense fur helps insulate organisms at the poles
What is: traps air against body?
What is: atmosphere warms, ice melts, albedo decreases, more heat absorbed, repeat?
Why winters at the poles are so long and cold (compared to rest of world)
What is: sun is at opposite end of Earth when winter at a pole = minimal light/heat?
How having thick blubber helps insulate against the cold polar environment
What is: thick, fatty, insulating layer to help trap heat against body's core?
Why it is bad to lose "old ice"
What is: old ice is the thickest and most stable, so now mostly thin, less stable ice?
