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).
Oceanic crust is mostly basaltic, which is denser, while continental crust is made from mostly basaltic and sedimentary rocks, which are less dense. This difference in density â¦ is why the oceanic crust sinks lower (thus the oceans) and the continental crust rides higher (thus the continents) on the mantle.ceanic crust is mostly basaltic, which is denser, while continental crust is made from mostly basaltic and sedimentary rocks, which are less dense.
