What do you need to revise? You have a test What do you need to revise?

You must answer one question from each of 6 sections So far we have covered 2 of them: 1A Water 1B Hazards Both of which form the 2 parts of people and the natural environment. By the way, I expect everyone to have a go at both sections, but I will bear in mind those who did not join the school at the beginning of term when I am using your results to help me write your reports

IGCSE comes in 2 levels Foundation and Higher Both papers use the same topics but ask easier questions in the Foundation. This paper is also shorter and expects less detail. What I have done, is do a mix of both papers, so there will some easy stuff and some that is a bit harder!

In a regular paper You will need to be able to do labelled diagrams – but obviously online, we cannot do that – but nearer the exam I will get you to practice drawing diagrams – and maybe scan them in? But not this time – I want them in during lesson time!

Looking at the first question The spec says: The world’s water supply is contained within a closed system – the hydrological cycle. Water is transferred between its various stores. the hydrological cycle: characteristics, stores & transfers. features of a drainage basin: watershed, source, mouth, channel network. the hydrograph (discharge, base flow, stormflow) and river regimes: factors affecting them (precipitation, temperature, water abstraction, dams). Case study of a named drainage basin to illustrate this content. Running water has a significant influence in the development of landforms. processes: erosion and deposition. Factors affecting these processes (stream velocity, slope, geology). formation of valleys, interlocking spurs, waterfalls, meanders, oxbow lakes, flood plains and levees. Named examples of landforms.

Looking at the first question Water is vital to people, varies in availability and therefore needs careful management. the water balance, areas of water surplus and water shortage. Named examples of water surplus and deficit areas the uses of water: agriculture, industry, human hygiene and leisure including the reasons for a rising demand. Named example of growing water usage in a country reasons for differences in water quality. Sources of pollution (sewage, industrial waste, agriculture). Managing the supply of clean water (dams and reservoirs; pipelines; treatment works). flooding: causes (intensity of rainfall, snowmelt, steep slopes, impermeable surfaces, human activities) and control (construction of spillways, embankments). Case studies of a dam or reservoir project, and flood defences in an urban area. This can all be found in the PowerPoints and notes you did or in the wiki on http://ysgol-rhyngrwyd-igcse.wikispaces.com/Unit+1A++Water+ and http://ysgol-rhyngrwyd-igcse.wikispaces.com/Unit+1A+Water+Part+2 And in the textbook p 1 - 32

Looking at the second question Having looked at several papers, I notice that they either ask about volcanoes with a bit on earthquakes Or a lot on earthquakes with a bit on volcanoes Or about tropical storms I will be kind and tell you that next week’s question is NOT about tropical storms That means ONLY learn about plate tectonics, volcanoes and earthquakes

Looking at the second question The spec says: Some places are more hazardous than others. different types of hazard (climatic, tectonic, etc.) the global distributions, causes (plate movements), and consequences (volcanic and earthquake activity) Named examples of areas prone tectonic events People can prepare for hazards, and they respond to events in different ways. coping with volcanic eruptions and earthquakes (predicting and taking precautions). Short-term effects (deaths and injuries, damaged buildings and infrastructure); long-term effects (homelessness; costs of repairing damage). after the event: short-term responses (emergency aid and disaster relief); long-term responses (risk assessment, adjustment, improving prediction). Case studies of the management of earthquakes and volcanic eruptions. One of each should have happened in an LEDC and the other in an MEDC.

Looking at the second question Where to find out about this: http://ysgol-rhyngrwyd-igcse.wikispaces.com/Unit+1B+Hazards And in the textbook: P35 - 46 What is being looked for: Key words – lists are both unit pages – put in as many as you can Named examples with some real information – not woolly stuff but real numbers – not too many – if it is a single event have the date. If people died, how many? And 3 or 4 other facts, so you can throw in at least one or 2 to show you really know about it.

Also … Be sure to answer what you are asked for If you are asked how people respond DON’T just say what happened – you may need to put this in to help explain – but the marks will be for what the people actually did – they evacuated people, they supplied emergency aid etc What happened is the effect of ….. So if you are asked for that – it will be things like the water was polluted, the houses fell down etc
