Q1.
Why do you think water is scarce in the desert?
Answer
Water is scarce in the desert because very little rain falls there.
- The book says a desert is a dry place with very little rainfall.
- The sun is very hot, so water left on the ground dries up quickly.
- The soil is sandy, so rain water sinks down fast instead of staying on top.
- There are very few rivers, ponds or lakes to hold water.
Why it matters: because water is scarce, people store every drop. That is why many desert houses have a tanka, a tank that keeps rain water for the dry months.
Did you know? Desert plants solve the same problem in their own way. A cactus stores water inside its thick stem.
