Q1.
Tick the image that will help in groundwater recharge. — Concrete road ☐ Green lawn ☐ Paved area ☐The three pictures printed with Activity 5 on page 9, redrawn here as simple sketches, with the tick box under each one.
Answer
Tick the middle picture — the Green lawn.
Picture
What its surface is like
Where the rain goes
Tick?
Concrete road
Hard, smooth, sealed tar and cement
Runs off the road straight into drains
✗
Green lawn
Soft soil covered with grass, with a big tree
Soaks in through the grass and soil, down to the groundwater
✓
Paved area
Stone slabs laid tightly over the ground
Runs off the slabs; only a little seeps through the joints
✗
Why the lawn wins: Rainwater can only become groundwater if it can get into the ground. Grass and soil are full of tiny gaps, and roots make small channels going down, so the rain sinks in. Concrete and stone slabs have no gaps. The water simply slides off them. That is why a city full of cemented surfaces loses its groundwater — the rain falls, but it never reaches the ground below.
What helps recharge: keeping some open, uncovered ground; digging soak pits; keeping ponds and human-made lakes; planting more trees. The johads of Rajasthan — small earthen dams that catch rainwater — have been doing this job for hundreds of years.
