The Earth's Crust is engineered precisely to support life

Earth's crust can be broken down into two categories: continental and oceanic

• Continental crust thickness is about 35 km
• Oceanic crust thickness is about 7 km

Thicker Crust?

• Too much oxygen would be transferred to the crust to support life

Thinner Crust?

• This would increase volcanic and tectonic activity to the point of making life untenable
