Question

What percentage of Earth’s surface is covered by water?

Answer 1

Hi!

The majority of Earth is covered in water. So, we can immediately eliminate A and B. 

After looking at the statistics, the United States Geological Survey has determined 71% of Earth's surface is covered by water!

Hopefully, this helps! =)

Answer 2

Seventy-one percent of the Earth is covered with water, which makes it looks like a blue ball floating around in space. The clouds swirl around Earth, blocking out parts of the land and sea.
