What is the significance of latitude in geography?

Latitude holds significant importance in geography, particularly in how it represents the distance from the Earth's equator, measured in degrees. The equator is designated as 0 degrees latitude, with values increasing to 90 degrees at the poles. This system helps in mapping the Earth and significantly influences various characteristics of regions.

Understanding latitude is critical for various purposes. It aids in navigation and in defining geographical boundaries. Additionally, latitude affects climate and weather patterns, as areas closer to the equator typically experience warmer temperatures due to direct sunlight throughout the year, while regions located at higher latitudes can have cooler climates. Consequently, latitude plays a foundational role in the study of geography as it organizes the Earth's surface.

The other options touch on related concepts but are not as directly tied to the core definition of latitude. While latitude can influence time zones and temperature zones and can have indirect relationships with ocean currents, its primary role is in measuring distance north and south of the equator, which is fundamental to understanding geographical positioning.
