The terms [[biogeochemical cycle]] and geochemical cycle cannot be used interchangeably because the former cycle includes the [[biosphere|biosphere component], while the geochemical cycle includes only the [[geochemistry|geochemical phenomena[[ of the Earth's [[geological reservoirs|reservoirs]]. However, the biogeochemical cycle refers to chemical interactions in surface reservoirs such as the [[atmosphere]], [[hydrosphere]], [[lithosphere]], and [[biosphere]], while the geochemical cycle refers to geochemical interactions that occur in reservoirs of the Earth's crust and sub-crust such as the deep Earth and the [[lithosphere]].

Some{{who|date=July 2022}} may use the terms [[biogeochemical cycle]] and geochemical cycle interchangeably because both cycles deal with Earth's [[geological reservoir|reservoirs]]. However, a biogeochemical cycle refers to the chemical interactions in surface reservoirs such as the [[atmosphere]], [[hydrosphere]], [[lithosphere]], and [[biosphere]]{{cn|date=July 2022}} whereas a geochemical cycle refers to the chemical interactions that exist in crustal and sub crustal reservoirs such as the deep earth and [[lithosphere]].{{cn|date=July 2022}}
