That Blue Square Thing - Geography Revision

Unit 6 Markscheme - Storms and Floods

WARNING! These pages are now very old. They were last updated in 2008 and the content applies to an old version of any geography syllabus currently active in the UK.
I've kept them here because there might be something useful for someone and the general marking principles aren't all that different. But be aware that it's old and out of date (the stuff on the Google Earth page in particular may not work at all)

Use this markscheme to check your own answers. If you're unsure then ask a teacher to give you a hand. With practice you should be able to mark your own work.

You might find it useful to look at the Standard GCSE Markscheme.

This explains a little more about level marked questions and gives an example. As examiners we're always interested to see useful case studies used in longer answers - this will often gain marks because it helps to explain the points you're making.

a) Study figure 1. Using this information:

(i) How long did the floods last?

Nearly 3 months (3 months is fine)

(ii) List three effects of the floods in Bangladesh.

Any 3 from: the capital was flooded; half the country was flooded; 1000 people died; power supplies collapsed; water supplies collpased; there was disease.

Note because the questions says "Using this information" you can ONLY use this information - you can't bring in anything of your own to go with it, no matter how good it is.

b) Suggest what some of the longer term problems of this flood might have been.

Level 1: Simple points made without development: cost of rebuilding; lack of power or clean water; problems with food; epidemic of disease etc...

Level 2: Some development of ideas, e.g. "Because half the country was flooded much food will be destroyed causing food supply problems. This means not everybody will have enough to eat, especially poorer people who may starve or be more vulnerable to diseases as a result"

c) Deforestation has taken place in the Himalayas Mountains to the north of Bangladesh. Explain how deforestation can lead to flooding.

This is quite a specific question but one that is clearly part of what you need to know. Deforestation is the cutting down of trees.

Level 1: Simple points: e.g. "Trees suck up water and slow it down"

Level 2: Some development: e.g. "Trees slow down water because their roots get in the way. If you cut them down the water gets into the river quicker so the water level is higher causing flooding"

Level 3: Well developed answer clearly showing good understanding of a complex idea, perhaps by bringing together ideas such as quicker surface runoff and increased soil erosion. An answer at this level will probably use complex vocabulary

d) Why do so many people all over the world live in areas which are likely to flood?

Level 1: simple points - people are poor, have no choice or because they don't think it will flood that badly.

Level 2: some development perhaps with brief case study material - "People believe that defences will protect them so they live on flood plains (e.g the Mississippi)"

Level 3: well developed answer with clear use of detailed case study material - "Because of population increase due to a high birth rate there isn't enough space for people to live anywhere else in Bangladesh. The country is so flat that there is no where to live which isn't likely to be flooded."

Notice how the use of case study material changes from Level 2 to Level 3. This shows how you can use case studies to really gain marks.
