Question

what is equater give answer in 100 words

Answer 1

An equator of a rotating spheroid (such as a planet) is its zeroth circle of latitude (parallel). It is the imaginary line on the spheroid's surface, equidistant from its poles, dividing it into northernand southern hemispheres. In other words, it is the intersection of the spheroid's surface with the planeperpendicular to its axis of rotation and midway between its poles.

On Earth, the Equator is about 40,075 kilometres (24,901 mi) long, of which 78.7% lies across water and 21.3% over land. Indonesia is the country with the longest equatorial line lay across the water and land.

Etymology

The name is derived from medieval Latin aequator, in the phrase circulus aequator diei et noctis ‘circle equalizing day and night’, from Latin aequare ‘make equal’.[1]
