Question

Give a geographical reason:

At some places along the coast, the low lying areas turn into lagoons or marshy lands.

Answer 1

1. Low-lying areas along the coast are flooded and drained by the saltwater brought in by the tides.
2. This process leads to a gradual deposition of some seawater and sediment in the low-lying areas.
3. In such a region, plants then take root and hold the soil firm against the force of tides and waves.
4. This gradually helps in maintaining mangroves and the coastal biodiversity in the low-lying areas. In this way, at some places along the coast, the low-lying areas turn into lagoons or marshy lands.
