Explanation
- Rainwater seeps into ground through infiltration .
- It moves through pore spaces in soil and rock.
- Wider spaces (gravel) → faster seepage; narrow spaces (clay) → very slow seepage.
- Water collects in pore spaces of underground sediments → called groundwater .
- Underground rock/sediment layers storing groundwater → called aquifers .
- We extract groundwater by digging wells .
- Drilling bore wells into aquifers also works.
