An equator is the intersection of a sphere's surface with the plane perpendicular to the sphere's axis of rotation and midway between the poles. The Equator usually refers to the Earth's equator: an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. Other planets and astronomical bodies have equators similarly defined. Earth's equator is about 40,075 kilometres (24,901 mi) long; 78.7% is across water and 21.3% is over land.
The latitude of the Earth's Equator is by definition 0° (zero degrees). The Equator is one of the five notable circles of latitude on Earth, with the others being the two Polar Circles: the Arctic Circle and the Antarctic Circle, and the two Tropical Circles: the Tropic of Cancer and the Tropic of Capricorn. The Equator is the only line of latitude which is also a great circle. The imaginary circle obtained when the Earth's equator is projected onto the sky is called the celestial equator.

TRICK to Remember Countries on Equator
http://mocomi.com/ presents : Why is it so hot near the Equator - Geography Videos for Kids Countries, towns and cities located around the equator experience hot weather throughout the year. It is because the sun remains almost directly overhead everyday. Countries that are further North or South of the equator experience a change in seasons, when hot weather follows cold weather. Living near the Equator – In places near the equator the sun’s rays are almost directly overhead thus keeping temperatures high. Living in places with seasons – Countries like United Kingdom and Korea, which are further North and South from the equator experience a change of four seasons. Living far from the Equator – In the Antarctic, the sun’s rays strike the Earth at a very low angle and this is why the c...
Have you ever wondered if water really goes down the plughole the other way on the other side of the equator?

Possible earth position after the pole shift
There is a profound connection between Nazca and Angkor Wat. Were these two ancient sites on the old equator at opposite ends of the earth? Other sites on this proposed old equatorial line might hold the answer. Charles Hapgood advocated the Earth crust displacement theory in a book entitled The Path of the Poles. Hapgood supported this theory with geomagnetic and carbon dated evidence. In a book entitled When the Sky Fell, Rose and Rand Flem-Ath also advocate the Earth crust displacement theory, with additional geological and archeological evidence. Both of these works conclude that the North Pole was located in the Yukon, at 63° N 135° W, approximately 80,000 to100,000 years ago. This is about 250 miles Northeast of the axis point for the line of ancient sites at 59° 42' N 139° 17' W....
Explains earth as oblate spheroid.But for small distances it can be taken as true sphere. Defines axis, poles, equator and meridian.
