Understanding Earth's Water Coverage
Earth is often referred to as the "Blue Planet" due to its vast oceans and water bodies. Approximately two-thirds of the planet's surface is covered with water.
Water Distribution
- Oceans: About 97% of Earth's water is found in the oceans, which are salty and cover around 71% of the Earth's surface.
- Freshwater Sources: The remaining 3% of Earth's water is fresh, primarily found in glaciers, ice caps, rivers, lakes, and underground aquifers.
Importance of Water Coverage
- Climate Regulation: Water plays a crucial role in regulating the Earth's climate and weather patterns.
- Habitats: Oceans and freshwater bodies provide essential habitats for countless species of plants and animals.
- Human Needs: Water is vital for human survival, agriculture, and industry, making its abundance critical for life.
Conclusion
In summary, the correct answer is option 'B' because two-thirds of the Earth's surface is indeed covered by water, highlighting the importance of this resource in sustaining life and maintaining ecological balance.
