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 made of a rock called basalt, which is darker and more dense than continental crust. You would only have to drill for about 7 km before crossing the Moho and entering the upper mantle. Below the Moho, the mantle extends to the surface of the Earth's outer core-about 2890 km down.hemical composition - 'crust' and 'mantle'. The surface of the Earth is the top of the 'crust' - whether one is under the sea or on land! By and large, the portions of the crust that poke above the sea to form land consist of 'continental crust' .
