tom swift among the diamond makers

 okay so right now we are kind of talking about the oceanic crust. which is a lot thinner than the earth like land crusts meaning magma gets through l0t easier. which as you know makes the mountains and things the oceanic crust is very ridgy and stuff like tons of ridges valley like things and chasms stuff. like that the earth had these formed easier because of the thinness of the oceanic crust like there is this mountain. that is most likely the largest mountain in the world underwater and it was most likely made by the magma coming up from the crust and making it going bigger. and bigger until it's what it is now.
