Glaciers of the Cryosphere
Questions for Class
1. Which of these apply to glaciers? (Check all that apply; hint: only one is not true!)
☐ a moving or deforming body of ice
☐ they are made of ice that lasts for more than two summers (perennial ice)
☐ they capture snow and grow in the winter and melt and shrink in the summer
☐ the largest glaciers are near the equator
☐ they are at risk because of climate change
2. Glaciers are important because: (check all that apply)
☐ they provide water during warm and dry seasons
☐ they store water for when our ecosystems need it most
☐ they produce oxygen through photosynthesis
☐ they help reduce global warming by reflecting solar rays
☐ they keep local environments cool because they are cold
3. Cryogenetic Powers include: (check the only one that DOES NOT apply)
☐ Frost Heave
☐ Solar radiation
☐ Frost Wedging
☐ Cryosuction
4. Frost Heave is a cryo-genetic power that expands frozen grounds and pushes rock to the surface
☐ True
☐ False
5. Ablation is another word for melt?
☐ True
☐ False
6. The Equilibrium Line of a Glacier is: (check two)
☐ the area between snow accumulation and ice melt on a glacier
☐ the terminus line of a glacier
☐ only a feature of a subsurface and invisible rock glacier
☐ is sometimes visible as the transition between white and grey surface color of a glacier
7. Seracs are: (check only one)
☐ blade-like cones of ice that resemble stalagmites
☐ large pieces of breaking glacier usually found at the terminus of a glacier
☐ tiny pieces of floating ice
☐ bits of ice that wedge between rocks and cause frost wedging
8. Rock Glaciers are: (check ALL that apply)
☐ a special type of glacier covered by rocks
☐ usually just below visible white glaciers, where it’s a little warmer
☐ the ice in rock glaciers is protected from heat by its rock cover
☐ rock glaciers can be found in all mountains
☐ climate change doesn’t affect rock glaciers because they are fully protected by their cover
9. Pingos are:
☐ both a natural land and ice form and a myth of the Eskimo culture
☐ are found in frozen earth (permafrost) environments
☐ can build up water and gas pressure beneath the surface of the Earth
☐ ice mounds that can erupt like volcanos with ice and water
☐ all of the above
☐ none of the above, Pingos are Arabian Horses that can walk on their hind legs
10. Why are glaciers blue on the inside: (choose only one)
☐ because that’s the color of water
☐ because the ice reflects the color of the sky
☐ because compacting ice pushes out oxygen
☐ it’s actually not blue, it’s an optical illusion, they’re actually white straight through the middle
11. Florida doesn’t have glaciers because: (check ALL that apply)
☐ it’s too warm for most of the year
☐ it doesn’t snow or have any perennial ice
☐ it doesn’t have high mountains and it’s far from the Earth’s poles
☐ glaciers never reach the sea and you’re always near a beach in Florida
12. Glaciers in the United States exist in: (check ALL that apply)
☐ Alaska
☐ The Appalachia
☐ The Rocky Mountains
☐ California’s Sierra Nevada
13. During an ICE AGE, sea levels will fall?
☐ True
☐ False
14. As the polar ice caps and mountains glaciers melt, sea level will surely rise?
☐ True
☐ False
15. What are the two types of Climate Change? (check 2)
☐ Natural (caused by natural phenomenon)
☐ Anthropogenic (caused by humans)
☐ Autochthonous (pertaining to the place you are in)
16. Which of these is not a Cryo-Power Superhero:
☐ Frozone
☐ Jack Frost
☐ Ice Cube
☐ Elsa
☐ The Yeti
