Locations with the same latitude do not fall in the same time zone. To cross all meridians, you have to travel 24,000 miles. So, I suppose the question wants you to find the parallels and meridians of the catenoid, and map those through the isometry. To cross all parallels, you have to travel 12,000 miles. Likewise, the Antarctic Circle, near the South Pole, is the location where the sun does not set around December 21st or rise around June 21st. begingroup A helicoid doesnt have parallels and meridians, as far as I know. The Arctic Circle, which surrounds the North Pole, marks the point where the sun does not set around June 21st or rise around December 21st. What Is the Difference Between Parallels and Meridians Parallel is an alternate term for a line of latitude on a map, while meridian is an alternate term for a line of longitude. diego poblets lank parallels and meridians lank remix Diego Poblets Lank - Parallels and Meridians Lank Remix, Diego Poblets Luis Bondio - Parallels and Meridians Luis. This latitude is mirrored by the Tropic of Capricorn in the southern hemisphere and receives the most direct sunlight around December 21st when the south pole is tilted toward the sun. The Tropic of Cancer located in the northern hemisphere is the point on Earth that receives the most direct sunlight around June 21st as the north pole tilts toward the sun. Other key points of latitude are the Tropic of Cancer (23в‚7вЂ™ N), Tropic of Capricorn (23в‚7вЂ™ S), the Arctic Circle (66вѓ0вЂ™ N), and the Antarctic Circle (66вѓ0вЂ™ S). It was not until 1884, when 22 countries met in Washington, D.C., and voted the Greenwich meridian as the international standard. In the 18th century most European countries chose a location unique to them and built their maps off of that reference point.

Greenwich has not always been the agreed-upon prime meridian. The prime meridian (zero degrees), today is located in Greenwich, London, United Kingdom.
