WAR

   A war is an act of fighting between two or more countries or opposing groups within a country, involving large numbers of soldiers and weapons. When a war breaks out, a lot of tragic consequences usually follow. Wars have short term and long term effects. The immediate effect of war is the death of people in large numbers, especially the youth. Soldiers not only suffers on the battlefield but also physically and psychologically. Because people are so close during wartime conditions, diseases such as tuberculosis could easily spread. Some emissions that come out of the weapons used in war can cause asthma, heart and respiratory conditions. Nerve gas leads to instant death.
     War also breeds emotional problems. The first world War is often associated with the syndrome called shell shock. This was originally believed to have a physical origin caused by the impact of loud shelling. However, it became clear that soldiers who had never been exposed to shells were developing the same symptoms. Because of its psychological origins, shell shock was defined as a neurosis and there was a little sympathy for shell shocked soldiers. War can also have a dramatic impact on the health of civilian populations. The radiation sickness and birth defects of children were problems experienced long after the buildings destroyed by the bomb were rebuilt.
    Wars also have environmental impacts. The application of weapons, the destruction of buildings and oil fields, fires, military transport movement and chemical spraying are all examples of the destroying effects of war on the environment. Air, water and soil are polluted, humans and animals are killed, and many health problems are left for those still living to nurse.

Natural soil

 Natural soils are influenced by rainfall and temperature,heavy rain causes the soil to become leached. High temperatures increase the rate of decomposition of organic matter in the soil, thereby lowering its humus content. Thus, climatic conditions tend to produce poor soils in the tropics and rich soils in the temperate regions. Besides climate and vegetation, the parent rock material also contributes to the quality of the soil. For example volcanic rocks tend to produce fertile soils.    Laterite, a red soil which is a product of leaching, is commonly found in the tropics. It is composed mainly of iron and aluminium compounds,and poor in humus and essential plant nutrients, such as phosphorus, nitrogen and potassium. The black and brown soil of the temperate grasslands are the world's richest soils, with a high mineral and humus content. The light coloured desert soils tend to be very rich in minerals but have a low humus content.    Mainly the soils ar...

Tin ore

    Tin ore and columbite are two minerals that co-occur in the form of heavy black grains like gunpowder, mixed with sand and gravel. They are deposited in alluvial beds of old river valleys and subsequently buried under layers of soil overburden. The ore is mined by the open cast method. To do this, a powerful machine called a dragline is used to first remove the overburden, and then to scoop out the tin ore which it piles in heaps called a monitor is used to direct a powerful jet of water to this tin wash, which washes it down through a series of sluice boxes. Here, the black, heavy tin grains together with other minerals like columbite, now called tin concentrates, sink to the bottom of the boxes, while the water carries the dirt and sand away.     At this stage, the columbite grains are separated from the pure tin concentrates. The concentrates are then sent to factories to be smelted refined and moulded in bars called tin ingots. It is in the form of either ...

READING AND UNDERSTANDING

All reading is geared to understanding. There would be no point in reading if we did not understand what we are reading. However there are many different obstacles in the way of easy understanding of a passage. It is your task as a reader to actively seek to break down the barriers to understanding.    One block to understanding is caused by references in the passage to things that are outside it. Pronoun are the first examples of words that refer to people and objects. Sometimes, it is easy to follow the reference at other times, it is more difficult. Look at the opening sentence of the passage you've just read that begins this way  "She was waiting for us:small, dowdy, dirty..."  Who was waiting? Who was the person waiting for? (Perhaps you would also like to know why she was waiting.)Answers to these questions will surely help you to understand and thus follow the reference. The first thing to do is to ask questions like the ones we have just asked and to read t...
