______________ of earth surface is covered with water?

Correct answer: C. 75%

  • A. 10%
  • B. 30%
  • C. 75%
  • D. 90%

Explanation

Approximately 71% of Earth's surface is covered by water, and this is conventionally rounded to about 75% in many biology texts. The 90% option greatly overestimates the coverage and may be chosen by confusing Earth's water-rich appearance with its actual surface proportion.
