The primary influence of latitude on climate is its effect on the angle and intensity of solar radiation received at different locations on Earth. Near the equator, areas receive more direct sunlight year-round, resulting in warmer temperatures and often supporting tropical climates. As latitude increases towards the poles, sunlight becomes less concentrated, leading to cooler temperatures and distinct seasonal changes. This variation influences ecosystems, precipitation patterns, and overall biodiversity, demonstrating how latitude serves as a fundamental factor in shaping regional climates.
