Which consequence is most directly related to Earth's axial tilt?

• A. Uniform Sunlight Across Latitudes
• B. Unequal Distribution of Sunlight and Seasons
• C. Sun Energy Greater at the Poles
• D. No Effect on Climate

Answer: (B)

Earth's axis is tilted relative to its orbit around the Sun, so the Sun’s rays strike different parts of the planet at different angles and for different lengths of time throughout the year. This tilt means that during part of the year a hemisphere is tipped toward the Sun, receiving more direct sunlight and longer days, while at other times it is tilted away, receiving less direct sunlight and shorter days. That unequal distribution of solar energy across latitudes and seasons is what creates the seasonal changes we experience. So the most direct consequence of the axial tilt is the uneven sunlight across latitudes that produces seasons. The other ideas don’t fit because the tilt prevents uniform sunlight, it does not make energy greater at the poles, and it certainly does affect climate by driving seasonal cycles.
