NOTE

LATITUDE AND LONGITUDE

Latitude is the angular distance of a location on Earth, measured in degrees north or south of the equator. The equator is the reference line, and latitudinal lines run parallel to it, ranging from 0° at the equator to 90°N at the North Pole and 90°S at the South Pole. Latitude is a key factor in determining climate zones and has implications for temperature and daylight variations across different regions.

Longitude is the angular distance of a location on Earth, measured in degrees east or west from the prime meridian. The prime meridian, running from the North Pole to the South Pole, serves as the reference line for longitude, with values ranging from 0° to 180°E or 180°W. Longitudinal lines converge at the poles. Longitude is crucial for pinpointing a specific location on Earth's surface and is used in navigation and mapping.

Important Lines of Latitude and Longitude

1. Latitude:

1. Equator (0°)
2. Tropic of Cancer (23.5°N)
3. Tropic of Capricorn (23.5°S)
4. Arctic Circle (66.5°N)
5. Antarctic Circle (66.5°S)

2. Longitude:

- Prime Meridian (0°)

- International Date Line (roughly 180°)

- 180th Meridian (opposite the Prime Meridian)

Uses of Latitude and Longitude

1. Navigation: Crucial for determining a specific location on Earth's surface.
2. Mapping: Essential for cartography and creating accurate maps.
3. Global Positioning System (GPS): Coordinates are used for precise location tracking.
4. Meteorology: Latitude and longitude help analyze and predict weather patterns.
5. Time Zones: Longitude is integral to defining time zones globally.

Similarities between latitude and longitude

1. Both are angular measurements used to specify a location on Earth.
2. Both lines are imaginary and run parallel (latitude) or converge at the poles (longitude).
3. Both lines are measured in degrees.

Differences between latitude and longitude

1. Latitude measures north-south, while longitude measures east-west.
2. Equator is the reference line for latitude, and the Prime Meridian is the reference line for longitude.
3. Latitude is expressed in degrees north or south, while longitude is in degrees east or west.
4. Longitude is related to time zones, affecting local time, whereas latitude does not influence time directly.

EVALUATION: 1. Describe the latitude and longitude of the earth

1. Identify 3 important lines of latitude and longitude
2. Identify 4 uses of latitude and longitude
3. Differentiate between latitude and longitude.

CLASSWORK: As in evaluation
