Most often the word equator in humans is associated with a median area of ​​land with a hot climate, where palms and "a lot of wild monkeys".This so-called equatorial climate zone land - the area between 5-8 degrees north and 11.4 degrees south latitude.Just as the equator - a line encircling the globe, equidistant from its poles.It is formed by the intersection of an imaginary planet's surface plane perpendicular to the axis of rotation of the Earth through its center.The length of the Earth's equator is 40,075.696 kilometers.The diameter of the Earth at the equator is 12,756 km.On this day, the line is always night.During the spring (March 21) and autumn (Sep
tember 23), the height of the equinox the Sun reaches the zenith of a peak here - 90 degrees.
from the equator begins geographic latitude 0 to 90 degrees to the north and south poles, respectively, while the globe conventionally divided into northern and southern hemisphere.All the parallel line passing through the point of the earth's surface is the equator of the earth are called parallels.

Equatorial natural area is the warmest in the world.Here, the smallest daily and annual changes in temperature: at a constant air temperature of 24 - * 28 ° C on average, they make up 2-3 degrees.At sea, fluctuations in general can be less than 1 ° C.
significant rainfall (from 3 000 mm per year to 8000 mm and above) exceeds evaporation, so the soil is mostly wetlands.In humid climates under constant showers and thunderstorms grow thick stacked wood.In the equatorial zone there are up to half of all species of flora and fauna of the earth.In the countries of equatorial climate zone is cultivated exotic cultures such as: pineapple, bananas, cocoa, sago and coconut trees.It is highly developed tourism industry.

addition to the geographical equator, distinguished yet as the celestial equator and the magnetic equator.Under the celestial equator means the great circle of the celestial sphere.The plane of this circle coincides with the plane of Earth's equator and is perpendicular to both the axis of the world with north and south poles, and the axis of rotation of the Earth.The celestial equator is the basis for the equatorial system of celestial coordinates.Magnetic Equator is a closed line on the Earth's surface, in which the intensity and inclination of the planet's magnetic field is zero.The geographical position of the magnetic equator of the Earth, as well as the magnetic pole, all the while gradually changing as a result of secular changes in the geomagnetic field.
