Study Notes
Earth’s Structure and Orientation
- Earth has a spherical shape, slightly flattened at the poles, resembling an orange.
- Latitude and longitude serve as invisible coordinates for pinpointing locations on the globe; latitudes are horizontal (East-West) and longitudes are vertical (North-South).
Latitudes
- Latitude lines, or parallels, measure distance from the equator, ranging from 0° at the equator to 90° at the poles.
- Each degree of latitude corresponds to an approximate distance of 69 miles.
- Significant latitudes include:
- Equator (0°): Divides the Northern and Southern Hemispheres.
- Tropic of Cancer: Marks the northernmost boundary of the Tropic Zone.
- Tropic of Capricorn: Defines the southernmost limit of the Tropic Zone.
- Arctic Circle (66.5° North) and Antarctic Circle (66.5° South): Indicate the edges of the polar zones.
Longitudes
- Longitude lines run from the North to the South Pole, measuring the distance from the prime meridian.
- Known as meridians, longitudes range from 0° at the prime meridian to 180° East and West.
- At the equator, the spacing between longitude lines is around 69 miles, decreasing to zero at the poles.
- The Prime Meridian (0°) runs through Greenwich, England, and is crucial for defining time zones and time calculations.
Time Zones and International Date Line
- The Earth is divided into 24 time zones, each covering a 15° segment of longitude.
- One degree of longitude equates to approximately 4 minutes of time difference.
- Events at Greenwich affect global time; for example, 11 AM in Greenwich corresponds to 4:30 PM in Kolkata, India.
Climate Zones
- Earth features three primary climate zones categorized by latitude:
- Tropic Zone: The hottest climate zone, encompassing nations like Colombia, Brazil, and Kenya.
- Temperate Zone: Characterized by moderate climates, includes countries such as India, Japan, and the USA.
- Polar Zone: The coldest climate zone, home to Norway, Iceland, and Finland, where penguins can be found.
