Question

Why is topsoil considered a non-renewable resource even though it is constantly being formed by weathering of rocks

Answer 1

Soil should be considered a non renewable resource due to the amount of time that is required to regenerate lost topsoil.  Geological time frames are required for the weathering of rock and decay of biomass to replace soil.
