1.Salt and Petrol Are Both Natural Resources That We Use Regularly. But Why Is Salt Cheaper Than Petrol?
- Natural resources need to be extracted and processed before use.
- Salt is mostly available from seawater. It is separated from seawater by the process of evaporation.
- On the other hand, petrol is a crude oil product that needs to be extracted from the depths of the Earth.
- It needs to be processed by the process of fractional distillation. Also, it is one of the non-renewable resources and hence not cheap.
