Unit 1 – Topic 2 – Changing Climates On your A3 sheet: What key terms can you remember?
Climate change Typical foundation exam question: (4 Marks) Describe how 2 human activities can contribute to climate change. What are the triggers in this question? Have a go!
Climate change Typical higher exam question: (4 Marks) For a named developing country, explain why climate change is likely to have a large impact on its people. What are the triggers in this question? Have a go!
A* answer Climate change is likely to have a large impact on the people of Egypt for several reasons. The river Nile flows through Egypt and several other countries. As countries further upstream become warmer and drier because of increased temperatures, they will desire more water. This therefore means that Egypt, who is on the lower course of the river could suffer by having less fresh water available as it has a restricted flow due to dams. As climate is getting warmer, natural disasters such as flooding and hurricanes are becoming more frequent. Cairo, which houses many people, sits on the Delta which is low lying and if sea levels rise then much of the coastline could be flooded.
