Above is a summary of all the topics from unit 1. Below are some questions you may want to look at with some worked answers. Past papers can be found here . Note there is unit 1, 2 and 3 papers here. In the mocks you will be doing a unit 3 and a unit 1 paper. Have a go at some of the questions from the link above. Bring them in to class so your teacher can have a look at them. ASK QUESTIONS! Useful Videos  from Edexcel. YOU DO NOT NEED THE COASTS CLIP THOUGH You will also find fact tests on the school website Qu. Explain how subduction zones generate both earthquakes and volcanoes. [6] •  At a subduction zone a dense ocean plate is pushed down into the mantle. •  Friction between the subducting plate and the plate above causes the plate to ‘stick’. •  Pressure builds up. •  Eventually the pressure is too much and the plate ‘snaps’ apart. •  The energy releases causes an earthquake. •  As the plate sinks it is heated. •  Some material melts and rises as

U sing a named location, explain how hydrometeorological hazards can contribute to a tectonic disaster. • tectonic disaster is when a hazard event causes widespread disruption. • The hydrometeorological hazards that combine with tectonic events include cyclones and associated flash flooding events and droughts • Cyclones are particularly prevalent within the tropics and sometimes occur in countries lying on multiple plate boundaries, e.g. Philippines • Tectonic events can leave steep slopes, rugged land and poor vegetation (if destroyed by, e.g., volcanoes) • Extreme weather events can trigger drought and forest fires that destroy vegetation (e.g. from El-Nino) and excess rainfall and flooding (e.g. from La Nina) • Heavy rainfall events trigger mudslides and landslides, particularly if vegetation has been removed • If heavy rain mixes with volcanic ash, then large lahars might kill many people (e.g. Typhoon Yunya in 1991) • Volcanic eruptions release lots of wate

Objectives: Identify a range of reasons as to why disasters are having larger impacts Understand that data is not always reliable Evaluate two different case studies of mega -disasters     Consider graphs of disasters since the 1960s from EM-DAT in terms of numbers affected, deaths and financial cost. Consider the reasons for these changes. Critically look at how disasters such as floods and drought compare in their trends compared to the tectonic disasters (geo physical. How do you think reporting of events has changed since the 1960's? (Consider technology and media) What impacts do these trends have? Mega-disasters (2004 Tsunami, 2010 Eyjafjallajokull eruption in Iceland, 2011 Japanese tsunami) all had global/regional impacts what were they?

C ompare the differences between the two tropical cyclone events. Paragraph 1 – Introduce what a tropical cyclone is (brief information on locations, formation, etc..). Describe the location of the two storms (Katrina and Haiyan) Paragraph 2 – Describe/explain the impacts of hurricane Katrina Paragraph 3 – Describe/explain the impacts of typhoon Haiyan Paragraph 4   - Compare the impacts and comment why you think those differences occur.   Useful sources of information: Katrina   Haiyan
