The Antarctic continent covers all latitudes south of roughly 75° South,
and all longitudes.
"85 degrees south" is a latitude. Every point at that latitude is on the Antarctic continent.
The Casey Research Station is located near the Antarctic coastline at approximately 66.27° S latitude and 110.52° E longitude.
Greenland is located at approximately 71.7069° N latitude and -42.6043° W longitude. The point in Antarctica that shares the same latitude and longitude as Greenland is near the Antarctic Peninsula, close to the western coast of Antarctica.
90° South latitude is the south pole, which is located on the Antarctic continent. The longitude doesn't even matter, because ALL longitudes converge at the poles.
Nothing (on Earth) is east of the equator. It's east of the prime meridian ... and it's called 66.5 degrees east longitude.
The Antarctic Circle is the collection of all the points on earth that are 23.5 degreessouth of the equator ... 23.5 degrees south latitude.
"85 degrees south" is a latitude. Every point at that latitude is on the Antarctic continent.
The Antarctic Circle is a line of latitude -- which moves, according to the Earth's wobble. As of 10 March 2016, it runs 66°33′46.1″ as a line of latitude and crosses all degrees of E and W longitude on Earth.
The South Pole is at 90 degrees S latitude. The North Pole is at 90 degrees N latitude. All lines of longitude converge at both poles. The Antarctic Circle is at 66 degrees 32 minutes S latitude. Most of the land mass of Antarctica is within the Antarctic Circle.
The Casey Research Station is located near the Antarctic coastline at approximately 66.27° S latitude and 110.52° E longitude.
Greenland is located at approximately 71.7069° N latitude and -42.6043° W longitude. The point in Antarctica that shares the same latitude and longitude as Greenland is near the Antarctic Peninsula, close to the western coast of Antarctica.
The Arctic circle is 66 33′ 39″ north and the Antarctic is the same south of the equator.Every longitude crosses both circles.
You may be looking for the Antarctic Circle, but all of the demarcations of latitude and longitude are circles.
90° South latitude is the south pole, which is located on the Antarctic continent. The longitude doesn't even matter, because ALL longitudes converge at the poles.
At 80°S and almost ANY longitude, you would be standing on Antarctic ice.
Nothing (on Earth) is east of the equator. It's east of the prime meridian ... and it's called 66.5 degrees east longitude.
Every meridian of longitude on Earth crosses the Antarctic Circle, the Arctic Circle, and every other parallel of latitude on Earth.
