#3070: Orogeny

XKCD comic, described below.
Transcript

[Cueball and Ponytail are seen from afar standing together on hill and looking out at a mountain range with mountains going all the way to the horizon, with more than 20 peaks. The hills they are standing on is grassy and strewn with rocks.]

Cueball: I hear these mountains are a billion years old.

Ponytail: Well, sort of.

[Close up of Cueball and Ponytail on a white background. Ponytail holds her hand palm up out towards Cueball.]

Ponytail: An ancient collision created the mountain belt, but the actual rock layers have been continually uplifted and eroded away.

[In a frame-less panel Cueball takes his hand to his chin looking down, while Ponytail now gestures away from Cueball with her palm held out.]

Cueball: So it's an old mountain range, but it's been fully renovated?

Ponytail: Yessir, torn down to the roots. This is good solid plutonic bedrock, freshly uplifted. Great value.

Ponytail: You in the market?

[They are now just standing normally talking to each other.]

Cueball: I dunno, I was looking for new construction. You got any emerging volcanic seamounts?

Ponytail: Nah, that market is a little too hot right now.
