Q 27 – Resources have value- discuss?
Ans –An object or substance becomes a resource only when it has a value. The usefulness of the object gives it value. As a resource is something that has utility, all resources have some value. The value of the object can be classified into two categories:
- Resources that have economic or commercial value.
2. Resources that do not have economic or commercial value.
Metal is a resource that has economic value as we make many products from it, for our daily use. On the other hand, the beautiful scenery you see may not have economic value but is still considered a resource as it is useful in giving pleasure to the human mind.
Q 28 – Write a brief note on wind power?
Ans – Wind power is the fastest-growing energy source in the world. A wind turbine works the opposite of a fan. Instead of using electricity to make wind, a turbine uses wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. The electricity is sent through transmission and distribution lines to a substation, then on to homes, business houses and schools.
Wind turbines do not have any adverse effect on the environment. That’s why wind power is gaining popularity. It is also becoming economically competitive with more conventional power sources – a fact that’s greatly improving its prospects as a viable energy source.
Q 29 – What are abiotic resources?
Ans – Abiotic Natural Resource :
- Abiotic resources comprise non-living things like land, water, air and minerals such as gold, iron, copper and silver.
- Abiotic resources are not renewable, as they can be exhausted by excessive use and their rate of formation is very slow.
- The usefulness of the abiotic resources depends upon their accessibility and their value.
- Their total reserve cannot be increased by human efforts.
- These resources are in great demand for the development of industries.
Q 30 – Write a brief note on Renewable resources?
Ans – Renewable Resources :
Renewable resources are resources which can be replaced or reproduced easily. Sunlight, air and wind are resources that are continuously available and their quantity is not affected by human consumption.
