The image below shows 7kn na87f;0 2nyoqssrglobal sea levelquiac24c9 h3 ns from the years 1880 to 2020.



1.There is a trend line showing changes in sea level from 1920 to 1960 and another trend line showing changes in sea level between 1980 and 2020. Describe the differences in sea level change between these two periods of time.
The increase in sea levels (as shown by the trend lines) is steeper for the years from    to    compared to the years from 1920 to 1960.
2.Outline the reasons for linking atmospheric carbon dioxide levels to the rise in sea levels.

Ecosystems growing in salt marshes are able to help reduce the effects of climate change by the sequestration (capture) of carbon. Sea level rise (SLR) has affected these ecosystems by flooding and eroding coastal areas.

The results from a recent study modelling the effects of a one-metre sea level rise on carbon sequestration by salt marshes in New York, United States, are shown in the graph below. The data shows the predicted effects by the year 2100.

3.Suggest an explanation for the difference in carbon sequestration between no SLR and one meter SLR, shown in the prediction graph.

4.Draw a diagram of the carbon cycle for a terrestrial ecosystem, and include carbon sinks, and processes associated with the cycle.
