Without being able to see the bar graph you're referring to, I can provide a general overview of how water is distributed on Earth.
Typically, the distribution of water on Earth is as follows:
-
Oceans: Approximately 97% of Earth's water is found in the oceans, which are salty and not suitable for drinking or irrigation.
-
Freshwater Sources: Only about 3% of Earth's water is freshwater, and of that:
- About 68% is locked in glaciers and ice caps.
- Approximately 30% is found underground in aquifers.
- The remaining 2% of freshwater is in lakes, rivers, and accessible reservoirs.
-
Atmospheric Water: A very small fraction of water (about 0.04%) is found in the atmosphere as water vapor.
Based on this general information, the explanation that most accurately describes the water on Earth would highlight that the vast majority is saltwater in the oceans, while only a small percentage is freshwater, most of which is not readily accessible for human use. If you provide specific details from the graph, I could give a more tailored response!
