Which of the following is NOT a basic tenet of plate tectonics?
A)Melted asthenosphere flows upward as magma and cools to form new ocean floor lithosphere.
B)The new lithosphere slowly moves laterally away from the zones of oceanic crust formation on top of the underlying asthenosphere (seafloor spreading).
C)When the leading edge of a moving slab of oceanic lithosphere collides with another slab,the older,colder,denser slab turns downward and is pulled by gravity back into the asthenosphere (subduction),while the less-dense,more buoyant slab overrides it.
D)The slab pulled into the asthenosphere begins the process of melting and moves into the liquid core.
E)The slab pulled into the asthenosphere begins the process of reabsorption into the mantle.

The slab pulled into the asthenosphere does not move into the liquid core - this is not a basic tenet of plate tectonics. Instead, it begins the process of melting and may eventually be reabsorbed into the mantle.
