Which of the following is the primary factor determining a region’s broad climate zone, such as tropical, temperate, or polar?

💡 Explanation:

Latitude is the primary factor because it determines the angle at which the sun's rays hit the Earth, influencing the amount of solar radiation received and thus the general temperature ranges that define the broad climate zones (tropical near the equator, polar near the poles, and temperate in between). While other factors like ocean currents, altitude, and proximity to water bodies influence local climates, latitude defines the major global zones.
