Quote:The above is from the website you linked to. Please discuss for us how “mountains perform the function of preventing shocks in the Earth”.Can we take this to mean that you accept mountains have "roots"?
Quote:This appears to contradict the geological record of how mountains were created.You're too hung up on this plate tectonics issue. If you look at the web page, it actually SAYS that mountains were created by upheaval of the earth when plates collide. It goes on to say that after they are created, they provide a stabilizing effect on the land.
As for your question about "shocks" -- again from the site:
Quote:...mountains extend to the surface layer joining lines on and below the surface, and nail these together. By fixing the Earth's crust they prevent any sliding over the magma layer or amongst the layers themselves. In short, mountains can be compared to nails holding strips of wood together. The fixing effect of mountains is known as isostasy in scientific literature. Isostasy is the state of equilibrium between the upward force created by the mantle layer and the downward force created by the Earth's crust. As mountains lose mass due to erosion, soil loss or melting of glaciers, they can gain mass from the formation of glaciers, volcanic explosions or soil formation. Therefore, as mountains grow lighter they are pressed upwards by the raising force implemented by the liquids. Alternatively, as they grow heavier they are pressed into the mantle by the force of gravity. Equilibrium between these two forces is established by isostasy.
