Which of the following is a major factor that causes weather?

• A. Uneven heat distribution
• B. Ocean currents
• C. Moon phases
• D. Earth's rotation

Answer: (A)

Weather comes from how the sun’s energy heats the Earth unevenly, creating temperature and air-pressure differences that drive moving air, clouds, and precipitation. Because land heats and cools faster than the ocean and because different regions receive different amounts of sunlight, some areas become warmer and rise air, while others remain cooler and push air toward those zones. This circulation sets up winds and the formation of weather systems. Ocean currents do help by redistributing heat and moisture, and Earth’s rotation shapes wind paths, but the initial and major cause of weather is the uneven heating that creates those pressure differences and drives atmospheric motion. Moon phases don’t have a direct, strong impact on weather patterns on short timescales.
