Longitudes are imaginary lines that run from north to south on Earth. They are essential in determining the location of a place east or west of the Prime Meridian. The Prime Meridian, passing through Greenwich, England, serves as the reference point for measuring longitudes. Understanding longitudes is crucial for accurate navigation and pinpointing specific locations on Earth.

Longitudes Defined and Significance in Geography
Longitudes are imaginary lines running from north to south on Earth, also known as meridians. They are defined as lines that connect the North Pole to the South Pole and are used to measure distances east and west of the Prime Meridian, which is located in Greenwich, England.
Defined as Imaginary Lines
- Longitudes are not physical lines on the Earth's surface but are imaginary lines used to locate positions accurately.
- They help in dividing the Earth into 360 equal sections, with each degree representing 1/360th of a full circle.
Significance in Geography
- Longitudes help in determining time zones around the world. Since Earth rotates 360 degrees in 24 hours, each degree of longitude represents 4 minutes of time difference.
- They are crucial for navigation and determining the exact location of a place on Earth's surface.
- Longitudes play a vital role in creating maps and globes, providing a framework for accurately representing the Earth's surface.
- They are essential for understanding climate patterns, ocean currents, and other geographical phenomena that are influenced by the Earth's rotation and position relative to the Sun.
In conclusion, longitudes are a fundamental concept in geography that helps us understand the Earth's structure, navigate accurately, and create maps that accurately represent our planet.
