Geographic Coordinate System(Science)

Exam 1

  • Coordinate System - Know how to locate different places on earth

    - specifically, the geographical coordinate system

  • Tropics - Countries located in this zone experience a tropical climate where the annual average temperature is above 18 degrees Celsius

  • Northern and Southern Temperature Zones- Countries located in these zones experience four seasons

  • Polar/Frigid Zone - Countries located in these zones experience cold temperatures all around

  • Coordinates - these are pairs of numbers with the position of a point

  • Latitude - are a parallel horizontal lines that have an equal distance to another

    - lines from 0° to 90° from northern and southern hemisphere(equator)

    • North pole - 90°N

    • Arctic Circle - 66.5°N

    • Tropic Of Cancer - 23.5°N

    • Tropic Of Capricorn - 23.5°S

    • Antarctic Circle - 66.5°S

    • South Pole - 90°S

  • Longitude - Vertical lines

    - called meridians

    - Lines are also numbered from 0° to 180° from eastern to western hemisphere(Prime Merdian)

    • Uk - 2°00’W

    • Spain - 4°00’W

    • Mali - 4°00’W

Locating Places on Earth Using a Coordinate System

  • Latitude and Longitude:

    • Latitude lines run east-west and measure north-south position on Earth.

    • Longitude lines run north-south and measure east-west position on Earth.

    • Coordinates are given in degrees, minutes, and seconds.

  • Equator and Prime Meridian:

    • The Equator is at 0 degrees latitude and divides the Earth into the Northern and Southern Hemispheres.

    • The Prime Meridian is at 0 degrees longitude and divides the Earth into the Eastern and Western Hemispheres.

  • Using Coordinates:

    • To locate a place, find its latitude and longitude coordinates.

    • Latitude is written first, followed by longitude.

    • For example, New York City is located at approximately 40.7128° N, 74.0060° W.

  • Grid System:

    • The Earth is divided into a grid system using lines of latitude and longitude.

    • Each line of latitude and longitude has a specific coordinate value.

  • GPS Technology:

    • GPS (Global Positioning System) uses satellites to determine precise locations on Earth.

    • GPS devices provide latitude and longitude coordinates for accurate positioning.

  • Applications:

    • Coordinates are used in navigation, mapping, surveying, and tracking.

    • They help in pinpointing exact locations on Earth's surface.

  • Conclusion:

    • A coordinate system, based on latitude and longitude, is essential for accurately locating places on Earth.

    • Understanding coordinates is crucial for navigation and mapping purposes.
