Antarctic Circle

The Antarctic Circle is south of the equator.
South
roughly 66.56 degrees south of it

The Arctic is around the northern hemisphere

The Antarctic is around the Southern Hemisphere (Antarctica)

Scientists and those who work in support of science live there temporarily: there are no permanent residents of Antarctica.
One hundred percent of the population of the Antarctic continent is temporary workers who are supported by their governments to study the health of planet earth. Generally, for each scientist, there are seven workers who support the scientific work.

None.

The few botanical specimens that can be found on the continent grow on the west side of a few areas on the Antarctic Peninsula.

They can grow, because there is sufficient sun, nutrient in the shallow, thawed soil and moisture to provide a nurturing growing environment for them.

None are part of any food chain.

It changes slightly every day, just like it does everywhere else on Earth.

On a single day, it could be anything between zero and 24 hours, depending

on the date, and exactly how far south of the Antarctic Circle you are. Over

the course of a whole year, it averages out to 12 hours for each day.

(Just like it does everywhere else on Earth.)

The Antarctic Circle crosses waters of the Southern Ocean, and land of Antarctica.
No point of it is on any part of any country, and there are no countries south of it,
between the circle and the south pole..

Twenty four hours is the length of any day on Earth.

Any land that the Antarctic Circle crosses is part of the Antarctic continent.

The Antarctic Circle is a circle of constant latitude, at roughly 23.5 degrees south.

The continent of Antarctica covers about 10% of the earth's surface. It is about as large as USA and Mexico, combined.

Both are theoretically the same. It depends on the accuracy of your measurements and the method of measurement. Are you measuring at exactly theoretical sea level or up and down mountains and valleys (along the sea floor?) etc. I do believer that the Earth is slightly larger south of the equator and so the Antarctic circle could be larger.

The equator is found at zero degrees and the South pole is found at 90 degrees S. You can measure this depending on the definition of nautical mile that you choose to use.

The closest point of Antarctic land to the equator is located at 69.5000° S.

Your math, then, will give you the answer you seek.

Due to the Antarctic Treaty, mining is prohibited. Iron ore, chromium, copper, gold, nickel, platinum and other minerals, and coal and hydrocarbons have been found in small, uncommercial quantities.

In summer it hovers just above zero. In winter it can drop to 40 degrees below zero.

In terms of Latitude, the arctic is the region above the arctic is the region north of 77 degrees north

Mercury freezes or at least does not expand and contract at the calculated rate under arctic conditions. I.E., the expansion coefficient of mercury does not allow it to operate at that extreme temperature so as to give accurate results.

The Arctic is north

There are none because nobody lives there except for a few scientists studying the ice.

The temperature of the Arctic varies widely because the Arctic is very large. In the summer, some continental locations can exceed 90 degrees Fahrenheit, while also dropping well below zero in the winter. It drops below freezing in all locations during the winter, though it is even warm enough to rain at times in the winter.

Antarctica belongs to the world and is protected by the United Nations and the Antarctic Treaty. Antarctica is the highest, driest, windiest, coldest, cleanest, most isolated and most peaceful continent on earth.

The Arctic Circle marks an area north of the Equator, and the Antarctic Circle marks an area south of the Equator, where there is at least one 24-hour period annually of no sunrise or sunset.

Never.

The Antarctic Circle marks the latitude on planet earth south of which at least one 24-hour period has no sunrise or no sunset.


All latitudes north of the Antarctic Circle experience one sunrise and one sunset each day...until the latitude of the Arctic Circle, where the reverse occurs.

Everywhere on earth experiences four seasons per year. The northern and southern hemisphere seasons are opposites of each other.

At the Arctic Circle, summer begins on June 21. At the Antarctic Circle, summer begins on December 21.

The answer will vary significantly depending on whether you're asking about the temperature or the location, both of which can be expressed in degrees.
