Question

______ moves groundwater into places where it collects, like ponds and rivers.
evaporation
sewers
sunlight
gravity

Explanation:

To determine the correct answer, we analyze each option:

• Evaporation is the process of liquid water turning into vapor, not moving groundwater to collection areas.
• Sewers are man - made structures for wastewater, not a natural process for moving groundwater to ponds/rivers.
• Sunlight provides energy for processes like evaporation, not for moving groundwater to collection sites.
• Gravity is a natural force that causes water (including groundwater) to flow downhill, which allows it to move into lower - lying collection areas like ponds and rivers.

Answer:

D. gravity
