The Equator is the circle of Latitude that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, about 40,075 km (24,901 mi) in circumference, halfway between the North and South poles. [Wikipedia]

| | equator | A CirclesOfLatitude an abstract east–west small circle connecting all locations around Earth (ignoring elevation) at a given latitude coordinate line.Circles of latitude are often called parallels because they are parallel to each other; that is, planes that contain any of these circles never intersect each other. A location's position along a circle of latitude is given by its longitude.There are five major circles of latitude from north to south are: ArcticCircle, TropicOfCancer, Equator, TropicOfCapricorn AnarcticCircle. The position of the Equator is fixed (90 degrees from Earth's axis of rotation) but the latitudes of the other circles depend on the tilt of this axis relative to the plane of Earth's orbit, and so are not perfectly fixed.

| | latitude | Latitude is the class of Regions, associated with areas on the Earth's surface, which are parallels measured in plane AngularDegrees from the Equator. |
| | object | Corresponds roughly to the class of ordinary objects. Examples include normal physical objects, geographical regions, and locations of Processes, the complement of Objects in the Physical class. In a 4D ontology, an Object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis. |
| | physical | An entity that has a location in space-time. Note that locations are themselves understood to have a location in space-time. |
| | region | A topographic location. Regions encompass surfaces of Objects, imaginary places, and GeographicAreas. Note that a Region is the only kind of Object which can be located at itself. Note too that Region is not a subclass of SelfConnectedObject, because some Regions, e.g. archipelagos, have parts which are not connected with one another. |
