Explain how variations in the intensity of sunlight can cause temperature differences on earth?

Variations in the intensity of sunlight received at different regions of the Earth are primarily due to the curvature of the planet and its axial tilt. Areas near the equator receive more direct sunlight, leading to higher temperatures, while polar regions receive sunlight at a slanted angle, resulting in lower temperatures. Seasonal changes also affect sunlight intensity, as the tilt of the Earth's axis causes varying exposure to sunlight throughout the year, further contributing to temperature differences. These factors collectively influence climate patterns and weather systems globally.
