Latitude lines Imaginary lines running horizontally around the globe. Also called parallels, latitude lines are equidistant from each other. Latitude is measured from 0° to 90° north and 0° to 90° south—90° north is the North Pole and 90° south is the South Pole.

Equator Zero degrees latitude. The equator divides the globe into the Northern and Southern hemispheres. The equator appears halfway between the North and South poles, at the widest circumference of the globe.

Longitude Lines Imaginary lines, also called meridians, running vertically around the globe. Unlike latitude lines, longitude lines are not parallel. Meridians meet at the poles and are widest apart at the equator. The degrees of longitude run 180° east and 180° west from the prime meridian.

Prime Meridian Zero degrees longitude (0°). The prime meridian divides the globe into the Western and Eastern hemispheres. The Earth's time zones are measured from the prime meridian. The time at 0° is called Greenwich Mean Time (GMT). With the Greenwich meridian as the starting point, each 15° east and west marks a new time zone.

Hemisphere A hemisphere is half the Earth's surface. The four hemispheres are the Northern and Southern hemispheres, divided by the equator (0° latitude), and the Eastern and Western hemispheres, divided by the prime meridian (0° longitude) and the International Date Line (180°).

Location- “Where is it?” -Absolute- It is shown by an address. The address can be any type that gives an exact position. -Relative- Saying where something is in relation to somewhere or something else shows it.

Place- “What is it like there?” -Human Characteristics- Things that have changed due to people -Physical Characteristics- Things that occur naturally
