Cartography involves making maps and using key geographic concepts like latitude, longitude, and map scale. Latitude ranges from 0 to 90 degrees north and south of the equator, while longitude extends from 0 to 360 degrees east and west of the Greenwich meridian. Map scale relates distances on a map to actual distances on earth. The most relevant lines for latitude and longitude are the equator, tropics, Arctic and Antarctic circles. The major continents are North America, South America, Europe, Africa, Antarctica, Australia, and Asia, with subcontinents including Indian, European, and West Asian regions.
