Study Notes
Locating Places on Earth
- Earth is spherical, with no corners or edges
- Landmarks (hills, rivers) help locate places
- Earth rotates on an axis with two fixed points: North Pole and South Pole
- These points are used as reference
- An imaginary circle called the Equator is drawn equidistant from the Poles
- The half of the Earth above the equator is the Northern Hemisphere, and the half below is the Southern Hemisphere
- The distance from a point on the earth's surface to the Equator is expressed as latitude
- Latitude lines are parallel, called parallels of latitude
- Measured in degrees; 0° at the Equator
- 90° at the North Pole, 90° at the South Pole
- Degrees are further divided into minutes and seconds
- 1° = 60 minutes, 1 minute = 60 seconds
Latitude
- Latitude lines are parallel
- Used to measure a place's distance from the Equator
- Measured in degrees, minutes, and seconds
- Degrees are numbered from 0° to 90° North and 0° to 90° South
- Each degree of latitude is divided into 60 minutes
- Each minute is divided into 60 seconds
- Angular distance to the equator
