Q: Is Equator the intersection of the surface of a rotating sphere with the plane that is perpendicular to the sphere's axis of rotation and midway between its poles? ¶
Q: Is Equator on the oceans or rainy throughout the year? ¶
Q: Is Equator 40,07? ¶
A: Yes, and 0,075.
Q: Is Equator modelled as a circle whose radius is a whole number of metres? ¶
Q: Is Equator at the elevation of 4,690 metres? ¶
A: Yes, and at 0°0′0″N 77°59′31″W, found on the southern slopes of Volcán Cayambe [summit 5,790 metres ] in Ecuador.
Q: Is Equator about 40,075 kilometres long? ¶
A: Yes, some 78.
Q: Is Equator about 43 kilometres greater than at the poles? ¶
Q: Is Equator by definition 0° of arc? ¶
Q: Is Equator one of the five notable circles of latitude on Earth? ¶
A: Yes, the other four are 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.
Q: Is Equator the only line of latitude which is also a great circle — that is? ¶
A: Yes, and one whose plane passes through the center of the globe.
Q: Is Equator not so easy to determine? ¶
Q: Is Equator not truly fixed? ¶
A: Yes, the true equatorial plane is perpendicular to the Earth's spin axis, which drifts about 9 metres during a year.
