Question

which phrase describes a feature of groundwater?
○ feeds rivers
○ provides habitats
○ makes up 75% of fresh water
○ used for hydroelectric power

Explanation:

• Groundwater discharges into rivers, sustaining their flow, so it feeds rivers.
• Surface water ecosystems (not groundwater) are typical habitats.
• Glacial ice makes up ~68% of Earth's freshwater, groundwater is ~30%, not 75%.
• Hydroelectric power relies on surface water (rivers, reservoirs), not groundwater.

Answer:

feeds rivers
