What is the significance of latitude and longitude?

Latitude and longitude are the fundamental coordinates used to pinpoint exact locations on Earth, making them essential for determining absolute location. Latitude lines run horizontally and help measure how far north or south a location is from the Equator, while longitude lines run vertically to show how far east or west a location is from the Prime Meridian. By using these two sets of coordinates together, any point on the Earth's surface can be identified with precision, which is critical for navigation, cartography, and geographic information systems.

The other options, while related to geography, do not accurately define the primary significance of latitude and longitude. For example, map orientation involves using various techniques and tools to determine direction but is not solely reliant on latitude and longitude. Climate zones are influenced by latitude, but these coordinates specifically provide individual location rather than broad climate categories. Political boundaries are established through human governance and do not pertain to the geographic coordinates that latitude and longitude represent. The clarity of absolute location provided by latitude and longitude is what sets them apart as crucial geographic tools.
