Question

Approximately 99.7% of all water on earth is found in oceans, seas, ice, and the atmosphere. based on this information, which statement is most accurate?

a) the earth's freshwater supply is infinite.
b) less than 0.3% of earth's water is drinkable.
c) humans are not dependent on ocean water.
d) the water cycle returns all usable water to the sea.

Answer 1

The most accurate statement regarding Earth's water sources is option B. less than 0.3% of Earth's water is drinkable because the vast majority is saline or trapped in glaciers.

correct option is b. less than 0.3% of earth's water is drinkable.

Step-by-step explanation:

Based on the information that approximately 99.7% of all water on Earth is found in oceans, seas, ice, and the atmosphere, the most accurate statement is that less than 0.3% of Earth's water is drinkable. The Earth's freshwater supply is not infinite; it is in fact quite limited. Freshwater includes water found in rivers, lakes, streams, and shallow groundwater which is a tiny fraction of the global water reservoir.

Most freshwater is trapped in glaciers and ice caps, particularly in Antarctica and Greenland, and is therefore not readily accessible for human use. Meanwhile, the vast majority of the planet's water is saline and found in oceans, which is not suitable for drinking without undergoing desalination treatments.
