Coastal flooding (e.g. on Sagar Island) has
increased due to ________ change brought about by
the enhanced greenhouse effect and _______
expansion/loss of the cryosphere store of water
Coastal flooding (e.g. on Sagar Island) has
increased due to eustatic change brought about by
the enhanced greenhouse effect and thermal
expansion/loss of the cryosphere store of water
The soil in the sunderbands has high levels of ___________.
The soil in the sunderbands has high levels of salinity (saltiness)
List the 4 risks to the sunderbands:
- Coastal Flooding (because of eustatic sea level rise)
- More intense and frequent cyclones (in the bay of bengal as a result of climate change)
- Increased coastal erosion (due to sea level rise and increased cyclone strength)
- Royal Bengal Tigers (risk to people due to deforestation and population growth destroying habitats)
Name the goods that the sunderbands can provid for people living there.
The mangrove forests of the Sundarbans provide a range of
goods (e.g. timber, fuel wood, fish & shrimp)
Name the services that the sunderbands can provid for people living there.
The mangrove forests of the Sundarbans provide a range of
services (e.g.
