3.10 - Case study - The Sundarbans Flashcards
Where are the Sundarbans?

The direction of the prevailing winds changes so moist air goes over land
What is a river delta?
low, flat land, sometimes shaped like a triangle, where a river divides into several smaller rivers before flowing into the sea
List 5 coastal processes in the Sundarbans
Tidal action (main) Erosion Monsoon winds Increasing sea levels Instability of islands
Define sustainability
Meet the needs of the present without compromising the needs of the future.
