I know theknot has a wedding budgeter but to me it seems unrealistic, it budgeted $800 for a photographerâ¦ I wish!
The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
On the other hand, continental crust remains where it is for billions of years and it is much older than oceanic crust. Composition of oceanic crust. Oceanic crust is made up of several layers with the topmost layer being just 500 meters thick. This is made up of basaltic rocks in the shape of pillows and sheets. The lower layer of oceanic crust is made up of two sub-layers that cover a thickness of 4.5 kilometers.
