Which percentage describes oceans' coverage of Earth's surface?

• A. 71 percent
• B. 60 percent
• C. 50 percent
• D. 80 percent

Answer: (A)

Understanding how much of Earth's surface is covered by oceans helps explain why oceans dominate the planet’s appearance and climate. Oceans cover about seven-tenths of the surface, with land making up the remaining fraction. This vast watery coverage shapes global climate, weather patterns, and the distribution of life. Among the given choices, the one describing oceans as occupying roughly seven-tenths of the surface matches this real distribution. The other percentages would imply far more land or far less water than actually exists.
