Why is the Arctic circle 66.5 degrees N?
The 66.5 degree angle comes from the tilt of the Earth's rotation axis (23.5°), such that 90° – 23.5° = 66.5°.
What is located at 66.5 N latitude?
This line of latitude is called the Arctic Circle . It is 66.5 degrees North of the equator.

What is largest latitude?
The equator is at 0∘. It is the longest latitude and is the only circle of latitude which is also a great circle.
Which is longest latitude Why?
Longest latitude: The equator is centred at a latitude of 0 degrees, meaning it is centred at the earth's circumference. As u know the sphere is the shape of the earth, that's why the equator is the longest latitude line.
What are the 4 main latitudes?
Besides the equator (0°), the North Pole (90°N) and the South Pole (90° S), there are four important parallels of latitudes– (i) Tropic of Cancer (23½° N) in the Northern Hemisphere. (ii) Tropic of Capricorn (23½° S) in the Southern Hemisphere. (iii) Arctic Circle at 66½° north of the equator.
What are the 3 types of latitude?
Technically, there are different kinds of latitude—geocentric, astronomical, and geographic (or geodetic)—but there are only minor differences between them. In most common references, geocentric latitude is implied.
Where is Arctic Circle located?
Arctic Circle, parallel, or line of latitude around the Earth, at approximately 66°30′ N. Because of the Earth's inclination of about 23 1/2° to the vertical, it marks the southern limit of the area within which, for one day or more each year, the Sun does not set (about June 21) or rise (about December 21).
What country owns the Arctic Circle?
The land within the Arctic Circle is divided among eight countries: Norway, Sweden, Finland, Russia, the United States (Alaska), Canada (Yukon, Northwest Territories, and Nunavut), Denmark (Greenland), and Iceland (where it passes through the small offshore island of Grímsey).
Can you live in the Arctic Circle?
While the total population of the Arctic Circle is only four million people, there are a number of cities that thrive in the region, such as Murmansk, Russia (population 295,374), Tromsø, Norway (population 75,638), and Utqiaġvik (formerly known as Barrow), Alaska (population 4,581).
What is 0 longitude called?
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. 6 – 12+ Earth Science, Geography.
Which is the zero degree latitude?
The Equator The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator.
What is 0 latitude called?
The equator The equator is the most well known parallel. At 0 degrees latitude, it equally divides the Earth into the Northern and Southern hemispheres. From the equator, latitude increases as you travel north or south, reaching 90 degrees at each pole.
What are the 7 latitudes?
The 7th parallel north is a circle of latitude that is 7 degrees north of the Earth's equatorial plane. It crosses Africa, the Indian Ocean, South Asia, Southeast Asia, the Pacific Ocean, South America and the Atlantic Ocean.
What is located at 23.5 S in latitude?
the Tropic of Capricorn This means that the Sun's vertical ray is striking the Earth at the Tropic of Capricorn (23.5 degrees S). Light extends 90 degrees in all directions from this point.
What is the 0 degree latitude line called?
The equator The equator is the most well known parallel. At 0 degrees latitude, it equally divides the Earth into the Northern and Southern hemispheres. From the equator, latitude increases as you travel north or south, reaching 90 degrees at each pole.
At what latitude do the Arctic and Antarctic circles lie?
4. Arctic Circle (Latitude 66.5oN). 5. Antarctic Circle (Latitude 66.5oS).
What is the latitude of North Pole?
90.0000° N, 135.0000° WNorth Pole / Coordinates
What city is closest to the Arctic Circle?
Longyearbyen, Svalbard, Norway. Longyearbyen is the starting point of our arctic cruise in the Svalbard archipelago.
Who owns the Arctic Circle?
So, who owns the Arctic? No one owns the North Pole, but every country with a border on the Arctic Ocean claims some of its waters. Because the North Pole is covered by an ice shelf and isn't actually land, it is governed by the Law of the Sea, a 1982 U.N. treaty signed by more than 150 countries.
Does null island exist?
Null Island is the point on the Earth's surface at zero degrees latitude and zero degrees longitude ( 0°N 0°E), i.e., where the prime meridian and the equator intersect. Null Island is located in international waters in the Atlantic Ocean, roughly 600 km off the coast of West Africa, in the Gulf of Guinea.
Why Greenwich is prime meridian?
There were two main reasons for the choice. The first was the fact that the USA had already chosen Greenwich as the basis for its own national time zone system. The second was that in the late 19th century, 72% of the world's commerce depended on sea-charts which used Greenwich as the Prime Meridian.
Where is the prime meridian?
Greenwich, England Any line of longitude (a meridian) can serve as the 0 longitude line. However, there is an international agreement that the meridian that runs through Greenwich, England, is considered the official prime meridian.
What is zero degree latitude is known as?
The Equator is the line of 0 degrees latitude.
Why is 23.5 degrees so important?
The axis of rotation of the Earth is tilted at an angle of 23.5 degrees away from vertical, perpendicular to the plane of our planet's orbit around the sun. The tilt of the Earth's axis is important, in that it governs the warming strength of the sun's energy.
What is 180 longitude called?
The international date line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway around the world from the prime meridian — the 0 degrees longitude line in Greenwich, England.
