Question
What are the various purposes for which the forest trees are cut?
✓
Answer
Trees are cut down for many reasons:
Trees are cut to make space to build new houses and to clear land to grow crops for human consumption, grass for animals like domestic and milch animals so they can produce dairy foods. The trees are also cut down for production of paper and making of furniture. Sometimes trees are cut to make roads and buildings.

The substance $W$ is a fossil fuel. It occurs deep below the ground in certain areas of the earth. Another fossil fuel $X$ is found trapped above the deposits of $W$. When $W$ is subjected to a process called $Y$, then a number of different products are collected at different temperature ranges which are put to different uses. A special grade of product $Z$ obtained in this way is used as aviation fuel in jet aeroplanes.
$a.$ What are $(i) W$, and $(ii) X$ ?

The fossil fuel $P$ is formed under the earth by the decomposition of vegetable matter lying under water by the action of anaerobic bacteria. The major component of fuel $P$ is $Q$. The fossil fuel $P$ is used as a source of gas $R$ needed to manufacture nitrogenous fertilisers. When $P$ is filled in metal cylinders and used as a fuel in motor vehicles, it is called $S$. What are $P, Q, R$ and $S?$
