Geography and belt between the two tropics, called tropical belt, climate, typical plants, seas and lands included in this area.
Tropics geography
The tropics are the two parallels of latitude 23 ° 27 ′ north and 23 ° 27 ′ south respectively called Tropic of Cancer and Tropic of Capricorn which correspond to the angle of inclination of the Earth's axis with respect to the vertical to the plane of the orbit.
They correspond to the maximum latitudes in which the sun's rays strike the earth perpendicularly at least one day in a year. They mark the demarcation between the tropical and the temperate belt.
Tropic of Cancer
The Tropic of Cancer is one of the two tropics on Earth and in astronomy it is represented by an imaginary line parallel to the equator at 23 ° 27 'northwards.
Cancer is said because the sun enters the constellation of the same name on the day corresponding to the summer solstice when, in the central hours of the day, the earth is hit perpendicularly by the sun's rays.
The territories and bodies of water crossed by the Tropic of Cancer are Algeria, Niger, Libya, Egypt, the Red Sea, the Arabian Sea, India, Bangladesh, Burma, China, the China Sea, Taiwan, the Pacific Ocean, Mexico, Saudi Arabia, the Emirates United Arab Emirates, Oman, Gulf of California, Caribbean Sea, Bahamas, Atlantic Ocean, Western Sahara, Mauritania, Mali.
Tropic of Capricorn
The Tropic of Capricorn instead includes the areas of the Earth where the sun culminates at the zenith at noon on the day of the winter solstice.
It is called Capricorn because the sun enters the constellation of Capricorn on the same day.
The Tropic of Capricorn crosses many areas of the earth including the Pacific Ocean, Chile, Argentina, Paraguay, Brazil, the Atlantic Ocean, Namibia, Botswana, South Africa, Mozambique, the Mozambique Channel, Madagascar, Indian Ocean and Australia.
Band between the two tropics or the tropical belt
The strip of land between the two tropics has a characteristic climate which is called tropical climate in which there are limited temperature excursions throughout the year and frequent rains of an often thunderstorm character.
In this area there is the tropical forest, a natural environment characterized by great biodiversity.

The fact that only two seasons alternate and the humidity is very high, favors the proliferation of lush vegetation, with some types of trees that reach heights of a few tens of meters, among the typical plants include the epiphyte, the lianas and ferns.
There are also many animals present including bats, colorful parrots, hummingbirds and even birds of Paradise, some varieties of snakes, iguanas, chameleons, geckos, giant toads, frogs, monkeys, jaguars and leopards.
Speaking of the tropics, the reference passes to the equator which is nothing more than the imaginary circumference placed between the two tropics that divides the terrestrial globe into two equal hemispheres called the northern hemisphere, the northern one and the southern hemisphere.
Terrestrial equator and tropics
The terrestrial equator together with the Tropic of Cancer, Tropic of Capricorn, Arctic Circle and Antarctic Polar Circle is also one of the five reference parallels and at it, in conjunction with the two equinoxes, day and night have the same duration.
The equatorial circumference crosses seas and lands including Gabon, Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia, Sumatra, Borneo, Sulawesi, Halmahera, Colombia and Brazil.
