Terraformation

A terraformation is something, generally a geologic formation or change, produced as a product of terraforming. This generally refers to something large but can also refer to something small. This term encompasses anything from a massive cliff to a small earthen shelf.

"That TERRAFORMATION is quite the sight. It must have been quite the undertaking" -Said the Minecraft player

(The referenced terraformation could be a cliff where there wasn't one previously, a massive lake, a ravine, or a small shelf build as a foundation for a home)
