DENDROLOGY

Detailed explanation-1: -Although renewable, soil takes a very long time to form-up to hundreds of millions of years. So, for human purposes, soil is a nonrenewable resource. It is also constantly depleted of nutrients through careless use, and eroded by wind and water.

Detailed explanation-2: -Soil is considered a renewable resource because it can be restored on a human timescale. When soil is lost by erosion it can be recovered fairly rapidly (a few decades) if better soil management practices are carried out. The fertility of soil can also be restored in a few years and thus soil is a renewable resource.

Detailed explanation-3: -Soil is considered a nonrenewable resource, which means its loss is not recoverable during a human lifespan since it can take 500 years or more for an inch of topsoil to form. As our population grows, comprehensive soil stewardship practices are more important than ever.

Detailed explanation-4: -The resources that can be restored or recycled over time through natural processes are renewable resources. Example-soil, forests, flora, fauna etc.
