Study Notes
Longitude Lines Overview
- Run in a north-south direction.
- Also known as meridians.
- Cross the equator and run from pole to pole.
- All lines of longitude are equal in length.
Degrees of Longitude
- Total of 360 degrees of longitude around the Earth.
- The line of longitude at 0 degrees is referred to as the Prime Meridian.
Prime Meridian Details
- Divides the Earth into the Eastern and Western Hemispheres.
- Passes through the Royal Observatory in Greenwich, England, and is also called the Greenwich Meridian.
Measurement and Geography
- The distance between longitude lines is consistent at the equator, approximately 69 miles (111 km).
- As latitude increases, particularly toward the poles, the distance between lines of longitude decreases to zero at the North and South Poles.
International Date Line
- Located generally at 180 degrees opposite of the Prime Meridian.
- Adjusts around specific regions and islands to prevent splitting countries into differing calendar days.
Time Zones
- The world is segmented into 23 one-hour slices and two 30-minute slices for time zones.
- Crossing the International Date Line when traveling from east to west adds a day to the calendar.
