Lack of erosion is the key to building mountains fast not rate of uplift, two millimeters a year, a moderate/slow rate of tectonic uplift will buy you 2000 metres in a million years without any erosion or nothing with moderate rainfall. The Manawatu Gorge in New Zealand has almost exactly this rate of uplift and matching erosion. | |

In a matter of moments, you can have a ring-shaped chain of mountains as large as you like, although it'll make a mess out of your planet, too. Any impact large enough to make a 1000 mile wide, 30k foot deep crater is going to have side effects like exposure of the mantle, ejecta blasted into space, and sterilization of your planet. By comparison, the Chicxulub crater that offed the dinosaurs is only 110 miles wide. But it will be fast! | |

| Mar 13, 2017 at 20:48 | comment | added | JDługosz | If you like the existing answers, remove the hard-science tag (use science-based instead. Maybe that’s what you meant? As a newcomer you might not have noticed that the former is special. | |

Continental drift is caused by tectonic plates shifting but a continent isn't necessarily limited to sitting one tectonic plate. Are your continents separated by sea? Or all together? | |

| Mar 13, 2017 at 13:50 | comment | added | Seventh Tiger | @LioElbammalf I thought continental drift was the same as the drift in tectonic plates. If not, feel free to correct me. At any rate, I intended for the continents to be on individual plates, so maybe this is moot. | |
| Mar 13, 2017 at 13:48 | comment | added | Lio Elbammalf | When you talk about continental drift are you using it as analogous to the drift in tectonic plates? (these are what butt together to push up and form mountains). Are your continents restricted to single tectonic plates? | |
