There are many imaginary lines that go around the Earth one way or another.

The Equator is the imaginary line halfway between the North and South Poles and is at zero degrees latitude. It divides the Earth into North and South Hemispheres. The Sun appears directly above the Equator at the Autumn and Spring equinox.

The Earth's axis passes through the centre of the Earth and is the point about which the Earth rotates. The north and south extremities of the axis are the North and South Poles. The South Pole is at 90 degrees S latitude and the North Pole is at 90 degrees N latitude.

The Prime Meridian based on Greenwich, England, is at 0 degrees longitude and all other meridians are "X" degrees east or west of it. The Prime Meridian was established for navigation and is the basis on which International time is kept.

The International Date line is on the opposite side of the Earth from the Prime Meridian and is the point which seperates yesterday from today. The line was drawn by international agreement, and was skillfully drawn so as not to cross any land to keep all areas of a country in the same day (and time zone). There are few bends and kinks in the International Date line to achieve this, but if it was a straight line, it would generally be at 180 degrees E or W longitude.

The Prime Meridian and the International Date Line are the two lines that separate the Eastern and Western Hemispheres.

The Antarctic Circle is at 66 degrees 32 minutes S latitude and marks the point on the Earth's surface where the Sun does not appear above the horizon at the southern Winter Solstice. It also marks the northernmost point of the Antarctic Frigid Zone.

The Arctic Circle is at 66 degrees 32 minutes N latitude and marks the point on the Earth's surface where the Sun does not appear above the horizon at the northern Winter Solstice. It also marks the southernmost point of the Arctic Frigid Zone.

The Tropic of Cancer is at approximately 23 degrees 30 minutes N latitude and marks the point on the Earth's surface where the Sun is directly overhead at the northern Summer Solstice. It also marks the northernmost point of the Tropic Zone.

The Tropic of Capricorn is at approximately 23 degrees 30 minutes S latitude and marks the point on the Earth's surface where the Sun is directly overhead at the southern Summer Solstice. It also marks the southernmost point of the Tropic Zone.

All other imaginary north-south lines are lines of longitude which are "X" degrees east or west of the Prime Meridian at Greenwich, England.

All other imaginary east-west lines are lines of latitude which are "X" degrees north or south of the Equator.
