Geography

Grade 5

Population: distribution and density

Module 25

Who lives where?

The distribution of the South African population

Activity 1:

To recognise densely populated regions in south africa on a map

[lo 1.1; 1.3]

Use an atlas with the above map and identify five urban areas with a large and dense population. Refer to the provincial boundaries to help you to work accurately.

Densely populated urban areas:

Physical factors that influence population distribution

A. The role that the discovery of minerals has played in the settlement of people in South Africa

Large population shifts occurred in South Africa after the discovery of diamonds by approximately 1870 near Kimberley and the discovery of gold in 1886 on the Witwatersrand. Until that time, the population in the interior of the country was relatively scattered. Then people started streaming to the gold and diamond fields and caused a great concentration of people. Soon cities were established where people had previously lived by farming on properties that were far apart from one another.

Mining of minerals

Remember that the mining activities soon also attracted other industries. Factories that manufactured mining equipment, were built and industries that provided in the daily needs of the people, were also established. Traders who sold the manufactured goods appeared on the scene. Minerals often provide the spark that sets off and maintains large-scale development.

Johannesburg, after the discovery of gold, was founded as a mining town, but had become a metropolis within 100 years. If all the gold mines in the region were to become exhausted, it would be a setback for the economy, but the city will continue to provide a large number of services and will therefore still provide work for millions of people.

B. Settlements are also influenced by factors other than the occurrence of mineral deposits

The presence of minerals is not the only factor that leads to settlement. Many fishing communities along the coast make a living from the sea and settle where there is a natural harbour or where a harbour has been built. Fishing therefore is the reason for settling and industries that deliver products to the fishing industry, or process fish, play a role in the creation of employment. Agriculture is a reason for settlement in many parts of South Africa, and in other parts it may be forestry.

Mining, agriculture, forestry and fishing are primary industries. They are first in the order of industries. After the primary industries, we have the secondary industries that process the primary products. At the fringe of the primary and secondary industries, we have trading, which allows products to be bought and sold. Transport plays an important role in the whole process and services also have to be provided where there are so many industries.

It is important to understand how all these processes are linked, but it is important to realise that people are employed in all these industries. The development of more products and building of more factories lead to the creation of better and more employment opportunities for people, who then also have a place to stay.

Activity 2:

To place different professions in categories

[lo 1.3]

  • Below there are ten statements. Place a tick in the appropriate column to indicate the city.

Refer to the maps of Southern Africa in your atlas. They provide information that will help you to choose the right answer.

Johannesburg Durban Cape Town
  1. This city has no significant mining activity.
  1. Industries provide equipment for gold mines.
  1. Many job opportunities in the sugar industry are nearby.
  1. The fishing industry is an important employer.
  1. Water may become a problem for the large population.
  1. Services are provided for the mining industry in general.
  1. The country’s densest railway network is nearby.
  1. The largest city in South Africa.
  1. The capital city of the smallest province.
  1. Capital city of the province with the largest population.

Assessment

LO 1

GEOGRAPHICAL ENQUIRY

The learner will be able to use enquiry skills to investigate geographical and environmental concepts and processes.

We know this when the learner:

1.1 with guidance, selects and uses sources of useful geographical information [finds sources];

1.2 distinguishes between facts and opinions [works with sources];

1.3 categorises information [works with sources];

1.4 uses an index to find places on global atlas maps [works with sources];

1.6 identifies and explores possible solutions to problems [answers the question];

1.7 demonstrates knowledge and under-standing of the issue through projects, discussion, debate and charts [communicates the answer].

  • Durban
  • Johannesburg

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi
🤔.

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?

this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
