Latitude significantly influences a region’s climate due to its effect on solar radiation distribution. Areas near the equator receive more direct sunlight year-round, resulting in consistently warmer temperatures. Conversely, regions at higher latitudes experience less direct sunlight, leading to cooler climates. The Sun plays a crucial role by providing the primary energy source driving weather patterns and temperature variations. Seasonal changes occur because of the Earth’s axial tilt, altering sun exposure throughout the year. Understanding latitude’s impact, alongside the Sun’s role, highlights why tropical, temperate, and polar climates vary dramatically across different geographical locations.
