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?

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?

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.

Case studiesNeed to know..... Glacials and Interglacials Natural causes: eruptions, sunspots, orbital theory Impacts on ecosystems and animals ( i.e. Dinosaurs) Enhanced Greenhouse effect Lost Vikings of Greenland Little Ice age UK Egypt

More exam questions Describe how one human activity can contribute to climate change (2) Describe how colder periods such as the little ice age affected people/farming (2) Describe one natural cause of changing climates (2) Explain the possible economic impacts of climate change on a named country. (4) State 2 possible impacts of climate change on the UK (2)
