6. What are the to ice sheet example and what are the size?

  • Arctic and greenland (14 times 10^6km2) (3times 10^6km2)
  • Arctic and greenland (14 x 10^6km2) (2 times 10^6km2)
  • Arctic and Greenland(13 times 10^6km2) (2times 10^6km2)
  • Arctic and Greenland (100 times 6km2) (8989 times 10km2)

7. What is surface albedo?

  • reflectivity of a surface, and how much is then relfeced off another surface
  • absorbtion of a surface
  • reflectivity of a surface, how much is reflected off
  • how much is absorbed by how much it is reflected off

8. What are ice bergs?

  • calve from iceshleves/ floating tongues, ice is less dense than water so it floats
  • calve from ice shelves/ floating tongues, whole ice thing sticks out
  • come from ice shelves/ floating tongues, ice is more dense than water os if floats
  • ice is ess dense than water so it floats but they are found on the shore

9. What are rivers of ice?

  • outlet glaicers, constrained by topography, common in artartical
  • contrained by toopography, found in greenland, and out inlet glaicers
  • outlet glaicers, constrained by topography,common in greenland
  • outlet glaicers, constrained by topography, common in the arctic

10. What is the order it from shortest to longest it takes for parts of the cysophere to form?

  • snow, sea ice, river/lake ice, glaciers andice caps, frozen ground, ice shseet margins and ice shelves and sheets
  • snow, ice, glaciers, sea ice, frozen ground, ice shelves, margins and sheet
  • snow, river/lake ice, sea ice, glaciers and ice caps, frozen ground, ice sheet margins, ice shelves and ice sheets
  • snow, river/lake ice, sea ice, forzen ground, glaciers and ice caps, ice sheet margins, ice shleves and ice sheets

11. What are calving events?

  • ice calving density
  • ice that is broken off from a glacier, ice berg, ice shelve which persists in the water, ice rafted debris can be used to data large calving events
  • ice break off density
  • ice grafter debriata calving events, and breaks off from glaicer

12. What glaicers are unconstrained by topography?

  • ice caps that more than 50'000km2 and ice sheets than are below 50'000km2, ice domes, ice sheets, ice streams and outlet glaciers
  • ice caps that are more than 100'000km2, outlet glaicers, ice domes, ice sheets, ice streams and ice divides
  • ice sheeets which are greater than 50'000km2 and ice caps that are less than 50'000 km2, ice domes, ice divides, outlet glaciers, ice streams and ice shelf
  • ice caps that are greater than 50'000 kn2 and ice sheets that are greater than this, ice streams, ice shelf, ice divides, ice domes

13. What is ael heiberg, canadian arctic examples of?

  • piedmont glaicers
  • surging glaicer
  • mountain glaicer
  • valley glacier

14. What is a mountain glacier?

  • has to be bigger that 0.01 km 2, examples are cirque, niche and glacienet
  • greater thatn 1km squared, cique niche
  • greater than0.001 km2
  • greater than 10 km2 anf found in mountains

15. What is the crysophere?

  • ice which is found in other planets aswell
  • the study of all things ice, which include ice caps, ice shelves, icebergs, ice sheets, glaciers, permafrost, mountains, snow cover and lake ice
  • just ice on the land
  • also the ground, grass found in those areas, sheets, glaciers, permafrost, mountains, snow cover and lake ice

16. What are ice streams?

  • constrained by topogra[hy
  • area more lubriactated than the area below it so they travel fast
  • contrained by free flowing ice, common in antartica, bed is more lubricated than the area underlying it so they travel fast
  • streams of staionary ice

17. What is hubbard glaicers, alaska exmaples off?

  • icefield glacier
  • surging glaicers
  • piedmont glaicers
  • tide water glaicers

18. When does the artic sea ice and antartica have its max extension and min?

  • artic has its max in march and min in march
  • antarticahas its max in sept and min in march
  • arctic max is in march, and min is in sept, antartica max is in sept and min in march
  • arctic sea ice has its max in septmeber and min in march and antartica has its max in march and min in spetember

19. What do geochemists and paeloclimatologists use to determine dates and rates of the land surface?

  • ultra-rare cosmogenic nucleides
  • cosmogenic technologies
  • rare consmogenic nucelotides
  • nucleotides
