1. Define natural resources
Natural resources are all those useful raw materials that we get from the earth. This means
human action turns naturally available things—air, water, soil and forests, into resources.
2. What percentage of the earth’s surface is land and how much of it can man use?
About 30% of the earth’s surface is land and we can use about 20% only.
8. Give reason for the need to increase the amount of arable land.
We need to increase arable land because as the world’s population increase and economy
expands the demand for land increases.
Therefore, we have to find ways to increase the land supply of usable land to meet the
growing need.
14. ‘More work in the world must be done on how to use water – explain this statement by
giving examples.
1. More work in the world must be done on how to reuse water because water which
was once considered an exhaustible natural resource has now been labeled as ‘a
scarce resource’.
2. One way is water harvesting where rainwater is collected to be reused again.
3. In Japan, a basin is attached over the flush so that the water to wash hands then goes
into the flush and is re-used.
I. Factories and industries should clean the water used before releasing it into water
sources so that the water can be reused.
II. Reuse excess drinking water.
III. When vegetables are washed the water can be reused to water the plants instead of
being thrown away.
IV. Dirty aquarium water can be used as fertilizer for the plants.
3. We construct roads and railway lines on land that helps us to travel from one place to
another.
4. We get minerals from land that is very essential for our development.
5. We build factories and other buildings on land.
