Terraform was a word for the deliberate alteration of a planet's atmosphere and ecology to create an environment suited to human life. The word came from the Latin word Terra, meaning Earth.[source needed]
Description or the process
The terraforming technology used in 25th century by Dollar Intergalactic, under the guidance of Professor Spector consisted of several phases and required three years. First, terraformer missiles were launched penetrating deep underground. Then, robe-drones were deployed to mine resources and construct Terra-Sphere towers with missiles used as their foundations. Once completed, the towers started generating a protective energy-field around the planet to facilitate the creation of a biosphere. Nanotek swarms released after that were used to modify the atmosphere, temperature, topography and ecology to given specifications. New species were created from organisms with hyper-evolution genes.

Examples of terraforming
The Tenth Doctor used an atmospheric converter to clear the skies of Earth from ATMOS poison in 2008. Luke Rattigan later used the same converter to blow up the Tenth Sontaran Battle Fleet and save Earth from invasion. (TV: The Poison Sky)
In the 25th century, Kano Dollar had the ice planet Isen VI into a jungle paradise. Unfortunately, this also awoke the Hyperion Rann-Korr. The Twelfth Doctor reversed the planet's terraformation, causing at least part of it to return to its original state. (COMIC: Terrorformer)
According to one account, by the 26th century, Mars had been completely terraformed by humans to make it habitable. They melted the icecaps and installed a gravity web to make an Earth-like planet, albeit with less gravity and more UV light. (PROSE: GodEngine, Beige Planet Mars)
According to another account, the Monk tried to alter history to make the Ice Warriors terraform Mars to make it as it was millions of years before the 23rd century and prevent the Ice Warriors from altering Halcyon's ecosystem, but was unsuccessful. While repairing the atmospheric re-ioniser for the Ice Warriors' use, the Eighth Doctor had altered the re-ioniser to make Mars' air 80% nitrogen and 20% oxygen. The destruction of Deimos Moonbase also lit up Deimos, making the moon into an artificial sun that heated Mars to make it warm enough for humans. (AUDIO: The Resurrection of Mars)
The Source was a creation myth for the people on the planet Messaline. The Tenth Doctor, Donna Noble, Martha Jones and the Doctor's daughter Jenny discovered it was a terraforming device. The Doctor released the device to trigger the terraforming of Messaline in 6012. (TV: The Doctor's Daughter)
Technically, terraforming was the transformation of a planet to a more Earth-like form, but other species had similar processes to adapt planets to a form more like their own home planets.
Theoretical Monsters: A Credibility Test referenced the Kalekani, a species who used a terraforming virus which converted land into flat grassland, effectively turning it into a golfcourse. Fitz Kreiner believed they were made up. (PROSE: Interference - Book One)
Terraforming was meant to modify the eco-system of a planet so that it resembled Earth and could be inhabited by humans. The humans did that to a lot of planets. However, terraforming could destroy the minerals that some humans wanted to mine. This was why the humans started to adapt. They modified their bodies to suit the alien environment. [which?] They completely reworked themselves and had new DNA sequences and new organs. (AUDIO: The Nu-Humans)
