What are Tropic of Cancer Capricorn Arctic Circle Antarctic Circle?

The Tropic of Cancer and Tropic of Capricorn are two of the five major latitude circles that mark the Earth's surface. They are located at approximately 23.5 degrees north and south of the equator, respectively. The Arctic Circle and Antarctic Circle are the two other major latitude circles, located at approximately 66.5 degrees north and south of the equator, respectively.

The Tropic of Cancer and Capricorn mark the northern and southern boundaries of the tropics, which is the area of the Earth's surface that is between the two tropics. The tropics are characterized by a warm, tropical climate. The Arctic and Antarctic Circles mark the boundaries of the polar regions, which are characterized by a cold, polar climate.

The Tropic of Cancer and Capricorn also mark the points on the Earth's surface where the Sun reaches its highest and lowest positions in the sky, respectively. On the summer solstice, the Sun is at its highest position in the sky over the Tropic of Cancer, and on the winter solstice, the Sun is at its lowest position in the sky over the Tropic of Capricorn.

The Arctic and Antarctic Circles are the points on the Earth's surface where the Sun does not set on the summer solstice, and does not rise on the winter solstice. This means that the polar regions experience a period of continuous daylight during the summer months, and a period of continuous darkness during the winter months.

The Tropic of Cancer and Capricorn, as well as the Arctic and Antarctic Circles, are important geographical features that help to define the different climate zones of the Earth's surface.
