Show the answer and explanation
CorrectNot quiteAnswer A
Correct answer: A
Explanation
About 97% of Earth's water is salt water in the oceans.
Only about 3% is fresh, and most of that is locked in ice caps and glaciers, so very little is easily available.
Worth noting
97% is the ocean's share, the reverse of what is asked.
