What is the primary cause of weather on Earth?

• A. The Moon's gravity
• B. Oceans tides
• C. The uneven heating of the atmosphere by the Sun
• D. The Earth's rotation only

Answer: (C)

Weather on Earth is driven by energy from the Sun. Sunlight doesn’t heat the planet evenly—land, water, and ice absorb and lose heat at different rates, and the amount of solar energy varies with latitude and season. These disparities create temperature and pressure differences in the atmosphere, causing warm air to rise, cooler air to move in, and moisture to condense into clouds and rain. The result is the constantly changing wind, storms, and precipitation we experience as weather. The Earth’s rotation influences how those air masses move and spin, shaping weather patterns, but it’s the Sun’s unequal heating that starts the whole process. The Moon’s gravity mainly affects tides, not weather.
