For the best results, bake a pie crust for about 15-20 minutes at 375F until it is golden brown and crispy.

The best crust to use for this dish is puff pastry. It is a finicky dough to use, but when used right it will produce the results you want.
In seafloor spreading, old crust is located further away from the mid-ocean ridges, where new crust is formed. As tectonic plates diverge and magma rises to create new oceanic crust, the older crust moves outward from the ridge. This results in a symmetrical pattern of age, with the youngest crust at the center of the ridge and progressively older crust extending towards the continental margins.
They are active under the crust, & they raise up new features.
Continental crust is less dense and thicker than oceanic crust, causing it to float higher on the mantle. The continental crust is also compositionally different, with a greater amount of less dense materials like granite compared to the basaltic composition of oceanic crust. This difference in density and composition results in the continental crust floating higher on the mantle.
The maximum age for oceanic crust is around 200 million years old. This is because the process of seafloor spreading results in older crust being recycled back into the mantle at subduction zones.
Oil can be used instead. It does however yield different results. Shortening will yield a firmer crust in baked goods, while oil will yield a soft crust.
