On the basis of availability, natural resources are divided into two types:
1. Renewable- These types of resources are available in infinite quantity and can be replenished naturally and used repeatedly.
Example- Sunlight, wind, water, etc.
2. Non-Renewable- These types of resources are limited because either they form slowly, or do not form naturally in the environment due to their non-renewable nature. Their availability may run out in the future.
