IGCSE GEOGRAPHY (4GEO)
THIS IS A SELECTION FROM THE SET OF PRACTICE QUESTIONS ( HANDOUT)
THE HANDOUT IS A SET OF NINE QUESTIONS.
These nine questions have been set by the Chief Examiner according to the official paper profile for the specification.
Question 1 : River environments(a)Study Figure 1 which shows a section of a river flowing through a
rural area. (i)On Figure 1, label : 1. the main channel 2. a source of the river
(2) (ii) On which of the following types of land use do the most
tributaries have have their source ? Arable Pasture Woodland ( Put a cross in the correct box)
(1) (iii) What is the discharge of a river ?
(1) (iv) Suggest why the highest discharge was found at monitoring
point D. (2)
(b)The availability of water helps to attract people to settle on flood plains. (i) Give reasons for the importance of water supply to people (4)(ii) Describe a flood plain (2)(iii) Explain how flood plains are formed. A diagram may help your answer.
(3)

River environments
Introduction
The velocity of a river is the speed at which water flows along it. The velocity will change along the course of any river, and is determined by factors such as the gradient ( how steeply the river is losing height), the volume of water, the shape of the river channel and the amount of friction created by the bed, rocks and plants.
Equipment
Velocity can be measured using very simple equipment. A watch capable of timing in seconds, something to float on the water and a tape measure are all that is required to find the velocity of the water surface. If you wish to find the velocity of the water below the surface, a velocity meter of some kind will also be required.
All about Floats
When measuring the velocity on the surface of the water it is common to time how long a float takes to travel a set distance. If you know how far it travelled and how long it took, you can find it's velocity.
There are certain things to look for in a float, apart from the obvious fact that it has to be able to float!
Firstly , you must be able to see it. Bright colours are much better than dull ones; transparent floats are not a good idea.
Secondly, it must be able to withstand some rough treatment, especially in fast flowing and turbulent water. Thirdly, it must not catch the wind. Only the water should be able to move it. A paper boat or any other float that
sticks well out of the water can be blown by the wind and won't give reliable readings. It is possible to buy special floats that are bright, strong and which float almost submerged, but they are expensive
and you are likely to lose a few every time you do some fieldwork. The good news, however, is that an Orange makes an excellent float, it's a bright colour, quite strong and it floats almost submerged so the wind doesn't blow it along. If you lose it you've only lost an orange; if you don't lose it you can eat it on the way home!
Describe how a fieldwork investigation into peoples’ views of the management of a hazard event could be carried out. (6)
tips!
*Survey on hazard management, people's views, making of questionnaires• Data presentation, analysis• * Conclusions and evaluation, improvements, limitations etc• (Planning and data collection will not be asked in section B)• Q:e.g.describe how youwould collect in the field(windspeed data,
precipitation data,temperature etc/record the data collected
