s the equator and the diameter the same thing?
no.
The Earths diameter is 12742km on average. It is a slightly squashed sphere though, due to its spin pushing out at the equator. Its polar diameter is 12714km, while its diameter at the equator is 12756km
No.
Saturn's diameter at its equator is about 74,900 miles (120,540 kilometers).
The diameter of the earth at the equator is about 25,000 miles, or about 40,000 kilometers
The diameter of Jupiter is 142,984km.
No. The Tropic of Cancer is parallel to the equator and 23.5 degrees north of it.

What causes currents to move north from the q Equator
The diameter of Earth at its equator is 12,756 km and its circumference is about 40,075 km.
... equator.
The equator is an imaginary line on the Earth's surface equidistant from the North Pole and South Pole that divides the Earth into a Northern Hemisphere and a Southern Hemisphere. http://en.wikipedia.org/wiki/Equator http://www.google.com/search?hl=en&q=Equator In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle. Greek words dia = through and metro = measure. The diameters are the longest chords of the circle. In more modern usage, the length of a diameter is also called the diameter. In this sense one speaks of "the" diameter rather than "a" diameter, because all diameters of a circle have the same length, this being twice the radius. http://en.wikipedia.org/wiki/Diameter
