Study Notes
Latitude
- Definition: Latitude refers to the geographic coordinate that specifies the north-south position of a point on the Earth's surface.
- Measurement: Measured in degrees, ranging from 0° at the Equator to 90° at the poles (North or South).
-
Key Lines:
- Equator: 0° latitude, divides the Earth into Northern and Southern Hemispheres.
- Tropic of Cancer: 23.5° N, marks the northernmost point of the Tropic zone.
- Tropic of Capricorn: 23.5° S, marks the southernmost point of the Tropic zone.
- Arctic Circle: 66.5° N, marks the latitude where the sun does not set on the summer solstice.
- Antarctic Circle: 66.5° S, marks the latitude where the sun does not rise on the winter solstice.
Longitude
- Definition: Longitude refers to the geographic coordinate that specifies the east-west position of a point on the Earth's surface.
- Measurement: Measured in degrees, ranging from 0° at the Prime Meridian to 180° east or west.
-
Key Lines:
- Prime Meridian: 0° longitude, runs through Greenwich, England, divides the Earth into Eastern and Western Hemispheres.
- International Date Line: Approximately 180° longitude, opposite the Prime Meridian, determines the change of one calendar day to the next.
Coordinate System
- Format: Coordinates are expressed as (latitude, longitude).
-
Examples:
- New York City: 40.7128° N, 74.0060° W.
- Sydney: 33.8688° S, 151.2093° E.
Importance
- Navigation: Essential for mapping, navigation, and global positioning systems (GPS).
- Geography: Helps in understanding climate zones, ecosystems, and human geography.
Visualization
- Grid System: Latitude and longitude create a grid overlay on the globe, aiding in locating any point on Earth.
- Maps: Used in various forms of maps, including political, physical, and thematic maps.
Latitude
- Latitude indicates the north-south positioning of a location on Earth's surface, integral for geographical referencing.
- It is quantified in degrees from 0° at the Equator to 90° at both poles (North or South).
- Equator: The central line at 0° latitude, dividing the globe into Northern and Southern Hemispheres.
- Tropic of Cancer: Located at 23.5° N, it signifies the northernmost reach of the Tropic region.
- Tropic of Capricorn: Found at 23.5° S, it denotes the southernmost limit of the Tropic zone.
- Arctic Circle: Situated at 66.5° N, it marks the latitude where the sun remains above the horizon during the summer solstice.
- Antarctic Circle: Located at 66.5° S, indicating the latitude where the sun remains below the horizon during the winter solstice.
Longitude
- Longitude identifies the east-west positioning of a location on Earth's surface, essential for navigation and geolocation.
- It is measured in degrees, starting from 0° at the Prime Meridian, extending to 180° both east and west.
- Prime Meridian: The zero-degree longitude line running through Greenwich, England, partitioning the Earth into Eastern and Western Hemispheres.
- International Date Line: Roughly at 180° longitude, this line marks where the date changes, serving as a reference for timekeeping.
Coordinate System
- Geographic coordinates are represented in the format (latitude, longitude).
- Examples:
- New York City: 40.7128° N, 74.0060° W
- Sydney: 33.8688° S, 151.2093° E
Importance
- Latitude and longitude are crucial for navigation, enhancing accuracy in mapping and global positioning systems (GPS).
- They enable a better understanding of climate zones, ecosystems, and human geography, which are essential for various fields of study.
Visualization
- Latitude and longitude create an effective grid system on the globe, allowing precise location identification of any point on Earth.
- Widely utilized in different types of maps, including political, physical, and thematic, to convey various geographical information.
