So do you think there is just air underneath the continent????? No there are tons and tons and tons and tons of dense thick mantle underneath holding up the crust

The math is there.

The...

Did you even bother to look at the schematic of a geology explanation of the Appalachian mountains? I am not making this up. Subduction occurs from Figure A to D. You can see Africa in figure D...

Here you go skippy, it is not me just making crap up.

Oh and by the way smarty pants I did take calculus based physics I and...

The old alluvial plain was pushed up and it then became highlands, a plateau. The plateau then becomes the target of erosion, winds and weathering which transports sediment away. However not all of...

The vast majority of non-volcanic mountain ranges on the Earth are formed by continent/continent collision. The Appalachians are an example, there is currently no subduction off of the east coast,...

Maybe you should actually pay attention to the video. Subduction ceases at :06 when all of the preceding oceanic crust is consumed. After that it is strictly continent/continent collision. No...

No, it is not some type of mystery.

When subduction was occurring that consisted of oceanic crust being subducted underneath continental crust. That is when you had the early period of vulcanism....

Oooooo, maybe the Tibetan Plateau is really a giant mushroom????

Or, how about a giant pancake?????? I SURE hope they have some GIANT MAPLE TREES around...

So the Tibetan Plateau is a petrified tree stump? LOL. Okay.

Dirt, soil is made up of clay minerals which are called hydrous alumino phylloslicates. They are basically decomposed continental...

OMG, from a geology perspective this is just obnoxiously ridiculous. Rocks just don't form willy nilly, their composition is directly related to their setting of emplacement and the geologic...
