Study Notes
Lines of Latitude and Longitude
- Latitude lines run parallel to the equator and measure distances north or south of the equator.
- Longitude lines run east and west of the prime meridian and measure distances east or west of the prime meridian.
- Both latitude and longitude are necessary to pinpoint exact locations on Earth.
Time Zones
- Earth has 24 time zones, each covering 15 degrees of longitude.
- These time zones help regulate daylight hours across the globe.
Maps
- Maps are flat representations of the Earth’s curved surface, using different projections for various purposes.
- Geologic maps help Earth scientists study large-scale geological formations.
- Most maps include a map legend that explains the symbols used on the map.
- The map scale indicates the ratio between distances on the map and actual distances on Earth's surface.
Modern Mapping
- Technology has transformed the appearance and use of maps.
- Remote sensing, a key aspect of modern cartography, utilizes satellites to gather data about Earth's features.
- Sonar is another tool for collecting data about features beneath the Earth's surface.
- GPS, a navigational tool integrated into numerous everyday objects, relies on satellites to pinpoint locations.
