Q 3
Question

Selvam from Cuddalore district, Tamil Nadu, shared that his village was less affected by the 2004 Tsunami compared to nearby villages due to the presence of mangrove forests. This surprised Sarita, Shabnam, and Shijo. They wondered if mangroves were protecting the village. Can you help them understand this?

Show answer Hide answer
Answer
Yes, the mangroves acted as a natural wall that slowed the tsunami waves.

Explanation

  • Mangroves have thick, tangled roots along the coast.
  • These roots slow down strong winds and waves.
  • So the force of the tsunami reaching the village was reduced.
  • That is why Selvam's village was less affected.
Mangroves protect coasts by slowing storms and waves.
