XKCD comic, described below.
Transcript

[Ponytail is looking at the ground in front of her, a hand on her hip. Cueball stands behind her, to the right.]

Ponytail: These tectonic plates look pretty eroded. When did you last flip them?

Cueball: Flip them?

[Zoom out to see the ground. Ponytail walks forward, motioning at the ground. Cueball spreads his arms behind her.]

Ponytail: Yeah, to use the underside of the continent.

Cueball: ...Never?

Ponytail: Wow. Explains the eons of weathering, debris basins, and ... is this isostatic depression?

Cueball: It's rebounding!

[Ponytail stops walking and turns to Cueball.]

Ponytail: You should really flip it. You'll get a whole new landscape!

Cueball: But I like this landscape!

[Ponytail spreads her arms slightly.]

Ponytail: Just think how warm and fresh the other side will feel.

Cueball: A sea of molten rock?

Ponytail: Good for the feet. Helps exfoliate.
