Year 11 GCSE Revison Advice

Make sure you learn your case studies over Easter. 

Task 1: Make sure you can answer the following questions

Water Landforms & People

  • What are Weather & Climate? make sure you know the difference between the two and their definitions
  • What are Weather Systems? e.g. depressions and anticyclones – case studies you can use here are the UK (Anticyclones) and Hurricane Katrina (Low pressure System) Make sure you know how it rains and the different types of rainfall e.g. convectional, relief and frontal.
  • How are people affected by climate? – Use the Indian Monsoon as a case study
  • How do people affect climate? Remember the Heat Island Effect and use Japan and the UK as a case study
  • How do ecosystems operate? Understand and be able to draw the rainforest system and the nutrient cycle within the forest e.g. precipitation, leaf twigs fall, nutrients, humus layer, leaching etc. Make sure you know what producers, primary consumers, secondary consumers and tertiary consumers are.  Be able to draw a food chain. (When explaining remember to explain in order e.g. start with the producer and work your way up the chain)  Know what will happen to an ecosystem if the food chain breaks
  • How do people affect ecosystems? Think about the following the immediate interest groups who are using the rainforest logging, mining, quarrying, farming, plantation owners, rubber tappers, tourists, pharmasutical companies etc – think about your work on the cross unit task.  Make sure you can explain what happens when the rainforest is destroyed e.g. how will this affect the local climate, local indigenous people, economy, also the physical changes in the forest e.g. soil erosion, lack of nutrients, rainfall due to lack of convectional rainfall rates. There are also positive impacts on the rainforest think how policies have been used to conserve the rainforest e.g. sustainable ways of using the rainforest.
  • How are people affected by ecosystems? This is on a global scale use the Greenhouse effect case study to link to a global impact.  On a local scale use the example of indigenous peoples.

Water Landforms & People

  • How does the hydrological cycle operate?Know your hydrological cycle and all the definitions.  Make sure you also know the drainage basin and all the associated terms.  Know the stores, transfers and inputs and outputs to the drainage basin.  Remember the drainage basin is an open system and the worlds hydrological cycle is a closed system.
  • How is water used & how does water supply vary?Understand the distribution of world water supplies and know that this is not equal.  Case study in the MEDC use the UK and compare water supply with England and Wales (Make sure you know your relief rainfall diagram).  Use the London Aquifer case study to look at problems of water abstraction. 
  • How do people Manage water?You can use the scheme of water transference in Portugal of creating reservoirs to generate hydroelectric power.  you can also use the Three Gorges Dam case study.  The three gorges is a good case study as you have many advantages and disadvantages to the scheme.  Use the UK as an example for managing drought (think about last summer in London).
  • How do people manage flooding? You can use the case study of Boscastle, UK for a MEDC and Bangladesh for a LEDC.  Make sure you can compare the two. Make sure you know about the flood hydrograph and know what influences the shape of the flood hydrograph e.g. intensity of rainfall, size and shape of basin, type of landuse e.g. urban/rural, type of geology, steepness of slopes and types of vegetation.  Be able to know the different features of a hydrograph e.g. rising limb, falling limb, lag time, discharge, cumecs etc and be able to work out what the lag time and base flow is.
  • How is quality of life affected by access to water? You used the example of access to clean water in Nepal and looked at the schemes that NGO’s and the government had set up to manage the issues.
  • What are the characteristics of a river valley? make sure you know the different stages of the river and what happens there.  e.g. the upper course, middle and lower.  Make sure you know what landforms operate on a river e.g. waterfalls, gorges, meanders, oxbow lakes, levees and deltas.  Make sure you also know how the river erodes material e.g. abrasion, corrosion, hydraulic action and attrition (CHAA).  Know about the rivers load and how it is transported e.g. saltation, suspension, traction and solution(SSST).  Know what the bed load is expected to be at each stage of the river. 
  • What are the processes and landforms operating on the coast line? This was your study and you should know what all the different processes of erosion, transport and deposition are that operate on the coastline e.g. LSD, Undercutting  sub aerial processes, slumping.  You should know about all the different landforms e.g. stacks, arches, stumps, spits, bays, headlands and how they have been formed. 
  • How do we manage coastlines? Again this was coursework and you should use the case study of North Norfolk to look at different sea defences and management techniques.  You should also be able to explain how each of these management techniques influence the coast line and what happens further down the coast?  You must also be able to explain what the different techniques such as holding the line and managed retreat means.

People Work & Development

  • How and why employment structures differ?understand what primary, secondary, tertiary and quaternary industry is and how they differ between MEDC’s and LEDC’s e.g. how does a country’s stage of development influence its percentage of people working in each sector.
  • How & what indicators do we use to measure development? Understand GDP, GNP, Standard of Living and look at social indicators from the Human Development Index.
