If you trade a geodude into alola will it evolve into alolan geodude?

No, trading a Geodude into the Alola region will not cause it to evolve into Alolan Geodude. To obtain Alolan Geodude, you must catch it in the Alola region, as it has a different regional form. However, if you have a regular Geodude, you can evolve it into Golem, but it will remain the original form.
