Both imaginary lines are circles of constant latitude, 23.5 degrees from a pole of the earth's axis.
their both cold
Both the Arctic and the Southern Ocean are polar oceans.
Both these lines of latitude are about 66 degrees.
They both have polar weather conditions and climate, are near the northernmost or southernmost points of the earth. Both circle a pole (North or South pole), and are the same approximate distance from the equator. They're both located at approximately 66° 33' 44" latitude (North and South, respectively -- and they wobble with the Earth's wobble). Also, they both mark the extremities of Polar Day where there is a 24 hour period of sunlight and a 24 hour period of darkness at least once a year. They both support sea life, but each also has unique lifeforms adapted to the climate. Humpback whales, and krill swim in both the Arctic and the Southern Oceans. Arctic is North on the globe/earth. Antarctic is in the south. They both enclose lots of ice. They both have names starting with the letter 'A': they are both cold and icy. The Arctic and Antarctic Circles are alike because of their polar climates, magnetism, wildlife, and locations. They both have freezing climates and wildlife, especially with sperm whales traveling back and forth between them. They are also both located at 66.5 degrees latitude on maps. Both also contain magnetic poles that are part of the magnetic field on the planet.
The Arctic and Antarctic oceans are both near a pole of the Earth.The Antarctic and Arctic oceans are both cold, dark, remote, and close to the Earth's poles.The Arctic, as well as the Antarctice, are both cold and dark.
Both are polar.
They are alike because both are just alike..
These circles mark the point on beyond which the geography experiences at least one 24-hour period of no sunrise/ sunset annually. At the farthest extent -- polar geographies -- the period is six months long.
The Arctic and Antarctic Circles are each the same distance from their respective poles. Depending on the nearness of the poles, periods of continuous day or night vary from one day to six months at locations inside the circles. The circles are imaginary parallels of latitude on the surface of the earth at 66°30' south and north of their respective poles. They mark the southern and northern limits of the areas in which the sun does or does not rise and set on the winter and summer solstices.
They both have a center
they are both graphs.
They are all nouns.
