Technically, they are the latitudes farthest from the north and south poles that have a
continuous period of 24 hours without a sunset, and a similar period without a sunrise.
Mid-latitudes
Those are the "polar" regions.
"High" latitudes. The equator has a latitude of zero. The area between the Tropic of Cancer (at 23.5 degrees north) and the Tropic of Capricorn (at 23.5 degrees south) are the "tropics" or low latitudes. The "polar regions" are above the Arctic Circle or below the Antarctic Circle, where the latitudes are higher than 66.5 degrees (north or south) are "high". The areas between the tropics and the arctic/antarctic are called "mid-latitudes or "temperate zones".
Arctic Circle, Tropic Of Cancer, Equator, Tropic Of Capricorn, Antarctic Circle (from top to bottom)
There are five named latitudes: * The Arctic Circle, * The Tropic of Cancer, * The equator, * The Tropic of Capricorn and * The Antarctic Circle.
Antarctic Circle
The Arctic and the Antarctic
high latitudes
The Arctic Circle is north of the Equator; the Antarctic Circle is south of the Equator.
The Arctic and the Antarctic respectively.
They are called the middle latitudes, and include mostly regions with temperate climates.
