Isotherms in the Antarctic run in an east-west direction primarily due to the continent's polar location and the influence of the circumpolar current surrounding it. This current, along with the dominant westerly winds, helps distribute cold air and ocean temperatures more uniformly across the region. Additionally, the high elevation of the Antarctic interior contributes to a more stable temperature gradient, reinforcing the east-west orientation of isotherms. Consequently, temperature variations are less pronounced in the north-south direction.
Because the unequal distribution of land and water and ocean currents influence their direction.
Not all isotherms run in an east-west direction, but most of them do. This is because latitude determines the temperature and climate of different regions. For example, the Tropics have higher temperatures than the Polar regions because it is closer to the equator. Lines of latitude run in an east-west direction, and thus isotherms, which is type of contour line or surface on a map that connects or indicates points of equal temperature, usually run in an east-west direction too.
Isotherms connect points of equal temperature on a weather map. The lines of isotherms naturally run parallel to each other. Their spacing indicates temperature variance.
Isotherms that run straight across the map from east to west are typically found in the tropical regions near the equator. This is because the temperature in these regions is relatively consistent throughout the year due to the amount of sunlight they receive.

There are no countries on Antarctica.
The Antarctic Circle runs through the Southern Ocean, which surrounds Antarctica.
None.
New Zealand claims part of the Antarctic territory, but does not 'run' any of it. The Antarctic Treaty preserves the continent for the study of science. Claims are unacknowledged.
No point in the USA is less than about 5,900 miles from the Antarctic Circle.
