Arctic and Antarctic Geography Quiz

Question 1An illustrative grounded ice body shrinks from 735 km³ to 681 km³. Find the volume lost in km³, rounded to the nearest whole number.

Enter a number in km³.

Answers within 0.5 km³ of the expected value are accepted.

Question 2On a map centered on the North Pole, which arrangement should occupy the central region?

An ocean bordered by the surrounding continentsA land bridge connecting the surrounding continentsA high continent enclosed by a circulating oceanAn inland plateau joined to southern mountain ranges

Question 3A polar station has continuous daylight near its summer solstice. What causes this?

The orientation of Earth’s tilted axis during its orbitThe Sun orbiting above that station for the seasonA large annual decrease in the distance to the SunA temporary halt in Earth’s daily rotation

Question 4Floating sea ice melts next to a grounded glacier. Which contribution directly adds stored water to the ocean?

Loss of the white color on the floating surfaceRunoff from the glacier’s land-based iceThe break-up of an already floating sea-ice floeThe sideways movement of drifting ice between bays

Question 5Two sites share a latitude, but one is on a high continental interior and the other beside open water. Why compare more than latitude?

Equal latitude gives both sites the coastal temperatureLongitude supplies the missing seasonal solar energyElevation and ocean heat storage alter their climatesA coastline sets the interior’s elevation to sea level

Question 6On a rectangular map, a route looks longer than on a globe. What should a navigator check first?

The projection’s distortion of high-latitude geometryThe map’s legal status as a maritime claimThe vessel’s cargo mass as the cause of the stretchingThe number of ports as a correction to the drawing

Question 7A foundation warms ice-rich frozen ground beneath a polar building. What problem follows?

A stronger foundation because thawed soil becomes bedrockA reduction in building weight as underground ice meltsA rise in the ground’s freezing point caused by the buildingA loss of support followed by uneven settling

Question 8Researchers planning a southern expedition ask how the Antarctic Treaty System handles competing territorial positions. Which description fits?

It allocates a new territory to the team that arrives firstIt replaces the continent’s claims with one elected national governmentIt awards sovereignty according to each station’s annual budgetIt protects peaceful scientific work without resolving sovereignty claims

Question 9A polar marine animal times breeding to a seasonal food pulse. Which link explains the timing?

Interior glaciers provide the plankton eaten offshoreWinter darkness produces algae by replacing photosynthesisSunlit waters support producers that sustain feeding opportunitiesAnimal breeding fixes the length of the daylight season

Question 10An ice map from one summer is offered as evidence of a long-term regional trend. What additional evidence is most useful?

The map’s print size and the color assigned to the oceanComparable observations spanning multiple years and locationsThe number of national flags displayed on expedition buildingsA shipping advertisement describing favorable conditions
