1 Proto Earth (slightly cooked)
- Accretionary solar nebula
- 5.9 x 10^24 worth of asteroids (accretionary disc variety)
- gravity
1 Proto Sea (3% salinity preferred)
- 1.3 km^3 of water in icy asteroids
Before You Begin
Before you can create the perfect continental crust, you need to prepare your proto earth. Preheat environment to 1600 °C using the gravity in your accretionary solar nebula. Allow the accretionary process to clear an orbit, gathering about 5.9 x 10^24 worth of asteroids from the surrounding debris field. As your accretionary blob grows, it will begin to emit heat. Keep an eye on the temperature. You want to melt out the ice from your icy asteroids but you don't want to lose your water vapour. Your proto-earth will soon take on a molten appearance under the bombardment of asteroids.
Crumbly Continental Crust
1. Reduce heat
2. Your proto-earth will begin to form a thin blackened skin. Don't worry. Though unappealing, this is important for a proper crumbly crust.
3. Further reduce heat to simmer
4. Put a lid on and allow your proto-earth to simmer for about 200 Ma.
5. Keep an eye on the pot. Your proto-earth should be simmering gently and the blackened skin should sinking and reforming due to heat convection. If you don't see much surface activity, increase the heat slightly via asteroid bombardment.
6. The charcoaled skin of your proto-earth should be well steamed by now. Allow a few more million years to ensure a good accumulation of liquid water the top.
7. As the charcoaled coating is sinking and reforming, because of the increasingly high water content, you should begin to see the blackened skin replaced by more buoyant and much more appetizing andesitic chunks.
8. If you like, you can give your proto-earth a stir, helping stick the andesitic bits to each other.
9. Allow a few more million years on simmer, watching the heat carefully. When your crust reaches approximately fifteen to twenty percent coverage of the proto-earth, garnish and serve!
