1
Which statement correctly distinguishes Antarctica from the Arctic?
Correct answer: Antarctica is a rocky continent covered by a vast ice sheet. Antarctica is land capped by continental ice, whereas the Arctic is primarily an ocean covered by sea ice and bordered by continents.Why the distinction matters: Land ice and floating sea ice respond differently to climate and have different effects on global sea level.
2
Which combination best describes Antarctica?
Correct answer: Coldest, highest, driest and windiest continent. Antarctica combines extremely low temperatures, very little precipitation, powerful winds and the greatest average elevation of any continent because so much of its land is buried beneath thick ice.Desert science: A desert is defined by low precipitation, not by heat. Antarctica is therefore the world’s largest cold desert.
3
Approximately what percentage of Antarctica’s surface is free of snow and ice?
Correct answer: About 0.4%. Only a tiny fraction of Antarctica is exposed rock or ice-free ground; roughly 99.6% is covered by snow or ice. These limited ice-free areas are especially important habitats for terrestrial plants, microbes and invertebrates.Ecological value: Because usable land is so scarce, small changes in ice-free habitat can have outsized biological effects.
4
About how much of the world’s surface fresh water is stored in the Antarctic ice sheet?
Correct answer: About 90%. The Antarctic ice sheet is Earth’s largest store of frozen surface fresh water. Its enormous mass also raises the continent’s average elevation and depresses parts of the underlying bedrock.Global importance: Changes in land-based Antarctic ice affect sea level because meltwater can flow into the ocean.
5
What is the highest mountain in Antarctica?
Correct answer: Mount Vinson. Mount Vinson, also called Vinson Massif, rises to roughly 4,900 metres above sea level in the Ellsworth Mountains. It is one of the “Seven Summits,” the highest peaks on each continent.Elevation context: Even away from major peaks, Antarctica has the highest average elevation of all continents because of its thick ice sheet.
6
What makes the emperor penguin’s breeding cycle especially unusual?
Correct answer: It breeds during the Antarctic winter, and the male incubates the egg on his feet. Emperor penguins breed in some of Earth’s harshest weather. The male balances the single egg on his feet beneath a warm brood pouch while fasting and huddling with other males.Sea-ice connection: Most colonies depend on stable fast ice that lasts long enough for chicks to develop before entering the ocean.
7
Why are Antarctic krill so important to the Southern Ocean ecosystem?
Correct answer: They transfer energy from phytoplankton to many fish, seabirds, penguins, seals and whales. Krill feed largely on microscopic primary producers and are eaten by a wide range of predators, making them a central link in the Antarctic food web.Systems lesson: A small organism can support very large animals when it is abundant and efficiently connects lower and higher levels of a food web.
8
What can tiny air bubbles trapped in Antarctic ice cores reveal most directly?
Correct answer: The composition of Earth’s past atmosphere. As snow is compressed into ice, small samples of ancient air can become sealed inside bubbles. Scientists measure gases in those bubbles to reconstruct past atmospheric conditions, while the ice itself also preserves dust, volcanic chemicals and isotopic clues to temperature.Research value: Ice cores let scientists compare modern greenhouse-gas concentrations with natural variations across thousands of years.
9
Which principle is central to the Antarctic Treaty?
Correct answer: Antarctica is reserved for peaceful purposes and scientific cooperation. The Antarctic Treaty was signed in 1959 and entered into force in 1961. It protects freedom of scientific investigation, encourages cooperation and requires scientific observations and results to be shared freely.Governance significance: The treaty created an unusual international framework in which research and peaceful use take priority over military rivalry.
10
Why does severe Antarctic ozone depletion usually intensify when sunlight returns in Southern Hemisphere spring?
Correct answer: Sunlight activates chlorine and bromine chemistry prepared on cold polar stratospheric clouds. During the dark, extremely cold winter, reactions on polar stratospheric cloud particles convert human-produced chlorine and bromine compounds into more reactive forms. When sunlight returns, catalytic reactions rapidly destroy ozone.Important clarification: The ozone “hole” is a region of exceptionally depleted stratospheric ozone, not an empty opening in the atmosphere.
