Water has a larger heat retention capacity than the land has. The water, however, takes longer to heat during the day. Therefore the land reaches higher day temperatures than the water. The sea then has a “cool” influence from the sea to the land. During the night the land cools down much faster than the water, which then causes a “warm” influence from the sea to the land.

The result is that places along the coast or large water masses, experience a moderate temperature. The margin between maximum and minimum is not very big.

Hot water evaporates faster and better than cold water. There is more evaporation above a warm sea current. This results in a higher precipitation in areas that border on warm sea currents.

Relief

In grade 5 we learnt that the escarpment diverts the rain bearing winds and clouds away from the interior. Mountains also have a sunny side and a shady side. The sunny sides have higher average temperatures, and the shady sides have lower average temperatures.

2. Climate and vegetation

  • As climate exerts an effect on vegetation, we find that both vegetation and human activities are relatively similar over large areas. Where one region changes into another, we find that a gradual change occurs over a large area. Such an area is referred to as a transitional/intermediate zone . Forests do not suddenly change to grasslands, but the occurrence of trees gradually decreases and grasslands increase. The map on page 16 shows the different rainfall and vegetation regions of the world. Remember, there are no specific boundaries. Maps will therefore differ slightly from one another.
  • The interaction between plants, animals, soil and climate within a demarcated area develops an ecological system, which we simply call an ecosystem. (Ecosystem = a selection of plants and animals in their own environment.)
  • The largest ecosystems that have developed on the earth are known as biomes . (Biome = a large area that houses similar plants and animals and relates to the distribution of climatic regions).

Activity 2:

To study climatic information

[lo 1.2, 1.3, 1.5]

Study the climatic information in the table on page 15 and answer the following questions:

  • Determine the longitudinal and latitudinal position of each of these two cities. Which city is closest to the Equator?
  • In which countries are the cities situated?
  • Select a suitable scale and represent the climatological information graphically. Use a line graph to illustrate the temperature and a bar graph to illustrate the rainfall.
  • Which city experiences the greatest temperature fluctuations? How does this compare with where you live?
  • Explain why the temperatures are so high and the temperature variations so little for these two cities.
  • During which months do these cities experience the highest temperatures and have the highest rainfall? How does this compare with where you live?

  • reports on enquiries, through discussion, debate, structured writing, graphs, tables, maps and diagrams.
LO 2
GEOGRAPHICAL KNOWLEDGE AND UNDERSTANDINGThe learner will be able to demonstrate an environmental knowledge and understanding.
We know this when the learner:
  • explains why more people live in some places than others;
  • identifies how access to different kinds of resources influences development in different places;
  • describes some ways in which society has changed the environment.
LO 3
EXPLORING ISSUESThe learner will be able to make informed decisions about social and environmental issues and problems.
We know this when the learner:
  • identifies inequalities within and between societies;
  • analyses some of the factors that lead toward social and environmental inequality at different geographical scales and in different places;
  • evaluates actions that lead to the sharing of resources and reducing poverty in a particular context.

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

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

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.
