Sea Level Rise

General

100

What are the 2 main types of Sea Level Rise 

Eustatic and Isostatic Sea Level Rise 

200

What is the extrinsic orbital control influencing sea level change 

The Milankovitch Cycle 

300

How much, on average, does the sea level rise each year?

3mm each year 

Consequences

100

Coral reefs are at risk with increasing rates of coastal flooding

True!

200

Which are 3 of the main consequences of sea level rise leading to ecosystem losses: 

1) Permanent submergence of Land

2) Slowing down of AMOC  

3) Enhanced drainage 

4) Enhanced coastal erosion

5) Salinisation of soils and surface water

6) More frequent coastal flooding 

1) Permanent submergence of Land

2) More frequent coastal flooding

3) Salinisation of soils and surface water

300

What is NOT a consequence of impeded drainage? 

1) Desaturation of the soil 

2) Pushes water upriver 

3) Low oxygen conditions 

4) Water drains at a lower rate 

1) Desaturation of the soil

Adaptations

100

What is the new capital of Indonesia?

Nusantara

200

How long are the delta works 

80km

300

What are some disadvantages of sea walls? (List at least 2)

Expensive, don't absorb wave energy (damage), they limit local ecosystems and migration. 

Measurements

100

What does a tide gauge measure?

The relative sea level between the ocean surface and the land at that location 

200

Satellite alimetry determines sea surface height by comparing 2 satellite images... true or false?

False!

300

What are some nature based solutions to increasing floods? (List at least 3)

Mangroves, seagrasses, sand, dunes, salt marshes
