10 Question Geography Quiz: The Arctic Circle | Geography

Answer: It is 90° minus the Earth's tilt

The Earth's tilt is 23.5°.This means that the Arctic Circle is 90°-23.5°, which is 66.5°. On the opposite side of the Earth, the Antarctic Circle is 66.5°S. In the Northern Hemisphere, the Arctic Circle is the southernmost latitude where there there is a day without the sun setting, due to the Earth's tilt. Also, the Tropic of Cancer is 23.5°N, while the Tropic of Capricorn is 23.5°S, which also use the Earth's tilt in their definition.

Answer: A day without the sun crossing the horizon

At the Arctic Circle, the summer solstice is the only day of the year with a full 24 hours of daylight, and the winter solstice will be the only day without any. Going further north, a place will have more days of constant daylight (centered on the summer solstice) and an equal number of days of no daylight (centered on the winter solstice). At the exact location of the North Pole, there will be six months of constant daylight and six months of no daylight. South of the Antarctic Circle, a similar effect occurs.

The Aurora Borealis and temperatures below -40° can occur south of the Arctic Circle. Acceleration due to gravity increases slightly near the poles (9.8 m/s² to 9.83 m/s²), but it is nowhere near double.

Answer: Bering Strait

The Bering Strait connects the water north of it (Chukchi Sea and Arctic Ocean) with the water south of it (Bering Sea and Pacific Ocean). The Bering Sea and Bering Strait are named after an explorer named Vitus Bering who explored Russian land and waters surrounding Russia.

Answer: Northwest Territories

From west to east, first there is Alaska (which is part of the United States). Then there are three Canadian territories: Yukon, Northwest Territories, and Nunavut. These three territories have their southern border defined at 60°N.

Answer: Yes

Most of Greenland is north of the Arctic Circle. The exact percentage may be hard to tell, and looking at a map may be inaccurate due to map distortion, since Greenland is so far north. However, using a different map projection does not change the shape or size of the actual land in Greenland.

Answer: Iceland

The Earth's rotational tilt is not constant. Even though it changes extremely slowly, it still changes. An extremely small change of +0.01° N (+0° 0' 40'' N) can make mainland Iceland not cross the Arctic Circle.

Answer: Fjords

A fjord is a type of inlet created by glaciation. They are common on the west coast of Norway, and Norway is the country that is most famous for having them. Norway has many fjords on the coast and lakes inside the country, and the fjords often have islands just off the coast of the mainland, created by the same glacial processes.

Answer: Scandinavian Peninsula

The Scandinavian Peninsula includes all of Norway and Sweden, and the northern half of Finland. The Kola Peninsula is part of Russia, and it also crosses the Arctic Circle. The Iberian Peninsula includes Portugal and Spain, while the Arabian Peninsula includes several Asian countries including Oman and Yemen.

Answer: Russia

Estonia, Lithuania, and Latvia are too far south. While Russia connects to Finland by land across the Arctic Circle, there are still some areas of water along the Arctic Circle, since there are some bodies of water inside Russia that connect to the rest of the oceans. One of these is the White Sea.

Answer: 45%

Russia is huge lengthwise and it is the largest country in the world by area. It is bordered to the west by several European countries, and its east end is extremely close to Alaska. This means that it spans some of Europe and all of Asia. Russia is partially north of the Arctic Circle and partially south of the Arctic Circle.
