Accordingly, it is she who can have the maximum thickness in places of active mountain building. It is believed that the greatest thickness of the earth’s food can have in the Himalayas. Reach up to seventy kilometers. All this is determined using geophysical research methods that display the boundaries of propagation of various waves.
