What percentage of the Earth's surface is covered by oceans?

  1. 50%

  2. 71%

  3. 93%

  4. 25%

The correct answer is: 71%

The percentage of the Earth's surface covered by oceans is approximately 71%. This extensive coverage is a key aspect of Earth's geography, as oceans play a crucial role in regulating climate, supporting marine ecosystems, and influencing weather patterns. The vastness of the oceans contributes significantly to the planet's overall features and biological diversity. Understanding this figure is essential for grasping the environmental dynamics of our planet. The choices indicating lower percentages do not reflect the reality of the Earth’s surface composition.
