The difference between tropical and temperate climates is mainly the result of the amount of direct sunlight to reach earth’s surface.
Tropical climates generally receive more direct sunlight year-round, resulting in consistently high temperatures and distinct wet and dry seasons. In contrast, temperate climates experience more variation in sunlight due to Earth's tilt and orbit, leading to more pronounced seasonal changes in temperature and precipitation. While wind patterns and precipitation also play a role in climate distinctions, the primary factor affecting the types of climates is the intensity and angle of sunlight received.
