Renewable And Non - Renewable Resources
Natural resources can be classified into the renewable resources and non-renewable resources.
The resources which have the capacity or ability to reproduce or renew quickly are called renewable resources. They include solar and wind energy, water, soil, forests, etc. Some of the renewable resources can be destroyed due to careless use.
The non-renewable resources are limited in reserves and it may take thousands of years to renew them. For example, coal or petroleum if taken out completely, may take millions of years to produce them.
