Understanding Freshwater Distribution
Freshwater constitutes a small fraction of the Earth's total water supply, and a significant portion of this freshwater is stored in glaciers and ice caps.
Percentage of Freshwater in Glaciers and Ice
- Approximately 68.7% of the world's freshwater is locked in glaciers and ice, mainly in Antarctica and Greenland.
- This means that the correct answer to the question is option 'C', which states that 98% of the world's freshwater is trapped in glaciers and ice.
Significance of Glacial Freshwater
- Climate Regulation: Glaciers play a vital role in regulating global temperatures and climate patterns.
- Water Supply: Melting glaciers contribute to river systems, providing essential water supplies for millions of people.
- Biodiversity: Glacial environments support unique ecosystems and species adapted to cold conditions.
Other Freshwater Sources
- Groundwater: Approximately 30.1% of freshwater is stored as groundwater, which is crucial for agriculture and drinking water.
- Surface Water: Only about 1.2% of freshwater is found in lakes, rivers, and wetlands, highlighting the importance of glaciers as a freshwater resource.
Conclusion
In summary, glaciers and ice caps hold an astounding 98% of the world's freshwater, emphasizing their critical role in our planet's hydrological cycle and the importance of protecting these vital resources.
