Answer: 
Renewable resources can be replenished over months, years, or decades. 
Step-by-step explanation: 
- As the name suggests, the resources that possess the ability to renew themselves over a period of time (limited to a lifetime) are recognized as renewable resources. 
- These resources are generally found above the 'surface of the Earth' except a few exceptions. 
- They are mainly functional in a cycle that carries itself out at after specific intervals of time. 
- It is due to these cycles that the resources are regenerated. Such cycles of regeneration are not seen in the case of 'nonrenewable resources'.
