P Determine the pattern of the river system. The time lag is affected bythe amount of runoff and infiltration that occurs. You can gain easy marks for the recall of definitions in the single mark questions. A illustrates a rural settlement. The latitude changes but the longitude stays the same 3418.
Why are there more houses and plantations on a slope in a valley? East London, Bloemfontein Metropolis A main city in a region which is surrounded by dependent towns, e. This leads to an increase in soil erosion in these areas. Draw a cross-section from A to B For example, see Figures 1. It does not follow the laws which control bigger, formal businesses. Name the layer labelled C.
A National Curriculum and Assessment Policy Statement is a single, comprehensive, and concise policy document, which has replaced the Subject and Learning Area Statements, Learning Programme Guidelines and Subject Assessment Guidelines for all the subjects listed in the National Curriculum Statement for grade 12. Vertical exaggeration In mapwork, we draw a cross section view from the side of an area or landform to better understand what the area or landform looks like. There is in fact not an area of life that is not affected by mathematics. Yet, what is even more remarkable than this seeming complexity is the fact that things in the physical universe are knowable. Learn to redraw and label Figure 1. Write the basic concept on one side of a bit of paper. The release of the study comes after the city's health unit has raised the alarm over a suspected outbreak of diarrhoea in Durban after two children died and more than 150 people were hospitalised in the past three months.
Low pressure over the land see the low pressure cell in Figure 1. So as we look forward at the 21st century and some of the problems of poverty, disease and pollution that face us, it is partly to the physical sciences we need to turn. It is expensive to fix the problem and this decreases profits. South Africa's long-term urbanisation trend is partly the result of freer movement of people after apartheid. This can be roads or railway lines.
You may also be asked to explain the importance of mining to South Africa and the impact of mining on the environment. It is gentle if infiltration is slow as water takes longer to reach the river. River meander A series of bends in a river as it moves along the floodplain. Low-rainfall areas have very little cultivated land; few, if any, perennial rivers and many non- perennial rivers; and few rivers, indicating low drainage density. Calculate the magnetic bearing for 2012 from trig, beacon 101 C3 to spot height 676 C4 on the topographical map. A primary B secondary C tertiary D quaternary 7x1 7 4.
One could use buffering to demarcate the area around the river where flooding could occur and build outside this area S S 1x2 2 4. A grid B planned irregular C radial D unplanned irregular 1. A business in the informal economy, for example, doesn't pay tax. South Indian high pressure and the South Atlantic high pressure are closer to the land and further north 5. Advise the municipalities on how this problem can be solved sustainably. Civil engineers use mathematics to determine how to best design new structures; economists use mathematics to describe and predict how the economy will react to certain changes; investors use mathematics to price certain types of shares or calculate how risky particular investments are; software developers use mathematics for many of the algorithms such as Google searches and data security that make programmes useful. Indicate to which settlement each of the following descriptions refers.
Land use in rural settlements The largest land use in South Africa is agriculture. It results in only summer rainfall occurring on the plateau. A 10 times larger B 5 times larger C 5 times smaller D 10 times smaller 1. This town is the centre of the Cacadu municipal district's industry and farming. Main industrial regions in South Africa Figure 4. Refer to the weather station labelled D and describe the weather in terms of: cloud cover, wind speed, wind direction, air temperature, dewpoint temperature.
You do this by swopping the top and bottom numbers of the horizontal scale fraction and then multiplying the top of each fraction together and the bottom of each fraction together. Show all steps followed calculations. Approximately 12, 1% of the land is used for both commercial and subsistence cultivation of crops. Which slopes are the coldest? The line graph shows the volume of the river over time. This is shown in Figures 1. Calculate the area covered by block B3 on the Nelspruit topographical map in kilometres squared. Make sure you have all the necessary stationery for your exam, i.
The impact assessment report can be viewed on my English Mind the Gap study guide titles: Afrikaans Mind the Gap study guide titles:. The higher you go, the cooler it gets. Diagrams should be done in pencil only. This type of flow is very inefficient found on the upper course of a river. We will now look at two aspects of river systems: drainage density and drainage patterns.
In contrast, if you find a wide floodplain flat area alongside a river , meanders, marshes or vleis, and oxbow lakes, this is where the lower course of a river is found. Buildings are made of cardboard, zinc, plastic or wood, or any available materials. Marks will be allocated for these. Area 1 1 Area 5 24,5 °C 19 °C Area 11 has a higher average temperature than area 5. This improves the country's economy. V J i ii Figure 2.
