Questions & Answers

Q: Why is water scarcity a concern?

Water scarcity is a concern because even though the Earth appears blue due to the presence of water, only a small percentage of it is actually clean and available for use. This limited availability affects the survival of living organisms.

Q: How much of the Earth's water is actually usable?

Only 0.006 percent of the total water on Earth is usable for various purposes, which means the majority of the water is not clean enough to be used for drinking, cooking, or household purposes.

Q: In what forms does water exist?

Water exists in three forms: solid (ice, snow), liquid (lakes, oceans, rivers), and gaseous (clouds). Each form serves different purposes and plays a vital role in the Earth's ecosystem.

Q: Why is it important to provide clean water to living organisms?

The provision of clean water is important for the survival of living organisms as dirty water can lead to various diseases and eventual death. Clean water ensures the well-being and health of living organisms.

Summary & Key Takeaways

• Earth contains more than 50 percent water, but not all of it is clean and usable for drinking and household purposes.
