The 20 questions

  1. What is permafrost?

    • Ice that forms on rivers only in early spring
    • Ground that stays frozen all year, even in summer
    • A layer of sea ice that melts completely every summer
    • A thick crust of snow that never melts on mountains

  2. What does fragile mean when describing an ecosystem?

    • Very strong, so it can withstand any kind of change
    • Growing quickly in warm and wet conditions
    • Covered in thick ice for most of the year
    • Easily damaged, so small changes can cause big harm

  3. Which polar region is found around the North Pole?

    • The Antarctic
    • The Arctic
    • The Sahara
    • The Amazon

  4. Which polar region is mostly frozen sea rather than land?

    • The high mountains of the Andes
    • The tundra of the Taiga
    • The Arctic
    • The Antarctic

  5. What is a food web?

    • A map showing lines of latitude across the globe
    • A list of all the plants that grow in one biome
    • A single line showing the path of one nutrient through the soil
    • Many food chains joined up, showing who eats what

  6. What are phytoplankton?

    • Tiny sea plants that make food using sunlight
    • Large sea animals that feed on the seabed
    • Seaweed collected by fishermen as bait for catching large fish in the cold northern seas
    • Ice crystals that form in cold ocean water

  7. Which two features help polar animals keep warm?

    • Wide feet and a thick, fleshy stem
    • Large ears and long, thin legs
    • Thick fur or feathers and a layer of blubber
    • Waxy skin and sharp spines that stop the animal from losing its water

  8. Which description fits the polar biome best?

    • Mild all year, with regular rainfall in every month
    • Warm in winter and very hot in summer
    • Hot and wet all year, with heavy rain in every month
    • Freezing cold, dry and dark for much of the year

  9. The Canadian Arctic town of Resolute has very cold winters. What is a typical average temperature there in January?

    • About 4°C
    • About -15°C
    • About 26°C
    • About -32°C

  10. The Resolute graph shows rainfall never above 30 mm in any month. What does this show about the polar climate?

    • It is very wet all year, with heavy snowfall
    • It is very dry, even though it is extremely cold
    • It has heavy rain only in winter
    • It has high rainfall in summer, so plants grow everywhere

  11. Why might a polar bear's white fur help it hunt?

    • It helps the bear swim faster in warm sea water
    • It camouflages the bear against snow and ice while it hunts seals
    • It stops the bear from feeling cold during the summer
    • It attracts other polar bears to its territory, so the bear can share food with them on the ice

  12. What does a layer of blubber under a seal's skin do?

    • Makes the seal lighter so it floats more easily
    • Stores extra water for the dry season
    • Keeps heat in, like a thick coat
    • Helps the seal dig burrows in the permafrost

  13. Why does permafrost make it hard for plants to grow?

    • Roots become thick enough to support tall trees, which grow well in the cold polar soil
    • Roots store water in the frozen ground each winter
    • Roots grow faster because the soil is always warm
    • Roots cannot grow deep into frozen ground, so plants stay small and shallow-rooted

  14. Why does removing one species harm the whole food web in the polar regions?

    • Removing one species makes the others grow larger, because they no longer have to compete for food
    • Each species in the web eats only one kind of food
    • Other species depend on it for food, so their numbers can fall too
    • Species in polar webs do not interact with each other

  15. Phytoplankton start many polar sea food webs. What would happen if they declined sharply?

    • Polar bears would begin to make their own food from sunlight
    • Fish would increase because there would be fewer predators
    • Seals would gain extra energy directly from the sunlight that falls on the ice in summer
    • Animals that eat them, and the animals that eat those, would lose food

  16. Which example best shows a fragile polar food web?

    • Warm summers help seals grow thicker fur, so polar bears gain food
    • Melting ice creates more land for foxes, who have no competitors
    • Warmer weather creates more ice, which feeds the plankton and makes the sea richer for fish
    • Loss of sea ice reduces seal numbers, so polar bears lose a key food source

  17. Why is the polar biome described as fragile?

    • It has no food webs because animals never interact
    • It has few species and a simple food web, so small changes can have big effects
    • It has a warm climate, so changes do little harm because the animals can easily move south
    • It has thousands of plant species that change quickly

  18. Which statement best explains why both polar regions are so cold?

    • They are close to the Equator, where the air is always cold
    • They are surrounded by mountains that keep out the warm sea air
    • They are far from the Equator, so the Sun's energy is weak and spread out
    • They are covered by forests that block all the warmth from the Sun in the summer months

  19. Why are polar regions sometimes called cold deserts?

    • They have sand dunes that are always moving across the frozen ground in the summer
    • They are very cold and get little precipitation, so water is scarce
    • They are hot in summer and cold in winter with heavy rain
    • They receive huge amounts of rain each summer

  20. Which pair of animal and adaptation is correct?

    • Cactus: thick fur to keep out the Arctic cold
    • Polar bear: waxy skin and spines to stop water loss
    • Penguin: a thick layer of fat and wings adapted for swimming
    • Camel: wide feet to walk across frozen snow and find food in the Arctic winter
