Pre are you saying that gravity cannot cause things to rise?
Since you claim that gravity is largely responsible for moving continents, I want you to demonstrate exactly how gravity is responsible for moving the Himalayas a few kilometers vertically (against the force of gravity).
You don't have a clue,.... do you?
Nothing you just wrote answers the question.Gravity can, thus, be seen to be the driving force moving the lithospheric plates.
This just proves your "logic" is totally illogical.
So, gravity helps pull a mass downwards and you use this to "explain" how a mass (the Himalayas) moves upward. Maybe you should explain exactly how this happens,... oh,... wasn't that the question in the first place?If the Himalayas rose suddenly, as a result of an impact; how have rivers managed to cut through the range?
Large impacts create large cracks in land masses. Rivers use these.Is this another question you are not going to answer?
The question is peripheral and depends on context. For example, the moon's gravity causes the sea to rise in the Earth's gravitational well, but the sea falls in the Moon's gravitational well.
