What percentage of Earth's water is freshwater?

• A. 3%
• B. 10%
• C. 25%
• D. 5%

Answer: (A)

The correct answer is that approximately 3% of Earth's water is freshwater. This figure is significant because it highlights how limited freshwater resources are in comparison to the total volume of water on our planet. Out of the total water on Earth, which includes oceans, glaciers, and underground reservoirs, only a small fraction exists in forms accessible for human consumption, agriculture, and industry.

Most of the Earth's water is saline, found in oceans, making the freshwater percentage crucial for understanding global water availability. The majority of the world's freshwater is stored in glaciers and ice caps, with only a small portion available in lakes, rivers, and groundwater, which are vital for supporting ecosystems and human activities. Understanding the distribution of water helps emphasize the importance of water conservation and management.
