CASE STUDY-Great Barrier Reef

Question 1

Are sea levels rising faster than coral can grow?

Answer 1

yes

Question 2

Why is the GBR under even more threat from sea level rise?

Answer 2

it is low lying

Question 3

What is the predicted sea level rise going to be on the GBR from now to 2100?

Answer 3

0.68m

Question 4

What is the predicted sea level rise going to be in the world from now to 2100?

Answer 4

0.9m

Question 5

What rate has the sea level been rising at since 1991?

Answer 5

3mm per year

Question 6

what have been the modern causes of sea level change?

Answer 6

Thermal expansion and glaciers melting

Question 7

why is the GBR even less prepared for the rise in sea level?

Answer 7

while the change in sea level is rather small compared to past standards it hasn’t changed much in the past 6000 years so the reef is not prepared for it.
