Understanding Atoll Islands and Sea Level Rise

What is the expected sea level rise by the end of the century?

• Around four meters

• Around three meters

• Around two meters

• Around one meter

Which islands are particularly vulnerable to sea level rise?

• Desert islands

• Low-lying atoll islands

• Forest islands

• Mountainous islands

What did the 2018 study by Paul Kench reveal about the atoll islands of Tuvalu?

• All islands were shrinking

• Most islands were stable

• All islands were disappearing

• Most islands were growing

What conflicting experience did the residents of growing islands report?

• Improved living conditions

• Increased tourism

• No impact from climate change

• Experiencing climate change impacts

What is one potential solution for the survival of atoll islands?

• Utilizing natural flooding

• Constructing sea walls

• Building skyscrapers

• Relocating residents

How do natural processes help increase the elevation of atoll islands?

• By reducing coral reefs

• By depositing sediment

• By eroding the islands

• By increasing rainfall

What role do coral reefs play in the adaptation of atoll islands?

• They create sediment

• They increase temperature

• They provide food

• They block sunlight

What is a challenge for developed cities like Miami and New York in adapting to sea level rise?

• High population density

• Inability to accommodate flooding

• Lack of technology

• Excessive rainfall

What is a key factor in maintaining beaches and dunes in coastal environments?

• Increasing tourism

• Avoiding critical infrastructure

• Building more roads

• Planting more trees

What is the long-term outlook for sea level rise according to historical data?

• It will decrease

• It will stabilize soon

• It will continue to rise

• It will fluctuate randomly
