Which of the following statements is NOT true?
AWater suitable for drinking is called potable
BAll sources of water such as oceans, lakes, rivers and underground water together constitute the hydrosphere
COf the total fresh water, about 69% is in glaciers, 30% underground and less than 1% in lakes and rivers
DOn Earth, the fresh water available for use amounts to around 4% of the total water ✓ Correct
Correct answer: (D) On Earth, the fresh water available for use amounts to around 4% of the total water
Explanation
The false statement claims usable freshwater is about 4% of all water, whereas usable freshwater is a far smaller sliver, well under one percent.
The claim that drinkable water is called potable is correct.
The claim that oceans, lakes, rivers and groundwater together form the hydrosphere is correct.
The claim that roughly 69% of fresh water sits in glaciers, 30% underground and under 1% in lakes and rivers is correct.
Total fresh water itself is only about 2.5 to 3% of all water on Earth.
Most of that is locked in ice caps and deep aquifers beyond easy reach.
