To appropriately label the blank spaces in the water resources diagram, here are the most common storage categories for Earth's water resources:
- Oceans (covers about 97% of Earth's water)
- Freshwater (includes rivers, lakes, glaciers, and groundwater)
- Glaciers and Ice Caps (store a significant portion of freshwater)
- Groundwater (the largest source of usable freshwater)
You can assign these labels to the blank spaces based on the structure of the diagram you are working with. If you provide a visual or more specific details about the diagram, I can help you determine where each label should go!
