Unit 2 Ch 5 : Minerals and Energy Resources — Social Studies STD 10 — Question

Industrial and agricultural development depends on minerals.
Conservation of mineral resources is essential because:

1. Mineral resources are finite.
2. They are non-renewable.
3. It is valuable but short lived possession and is greatly required for our future generations.
4. Rate of consumption is more than the rate of replenishment.
5. If it is saved it can be used with better technologies in future.
6. Continuous extraction of ores leads to increase in cost and decrease in quality.

Three methods of conserving mineral resources are:

1. Recycling of metals:

1. Metals which are used once can be recycled and reused again.
2. Scrap metals and other substitutes are steps in conserving our resources for future.

2. Use of resources in a planned and sustainable manner:

Minerals resources should be used in a limited amount. Renewable resources can be used as alternatives.

3. Improved technologies:

Machineries should be of good quality. Improved technologies need to be constantly evolved to allow use of low grade ores at low cost.

4. Using scrap metals and other substitutes.
