CONITNENTIAL this is one of the Witchtower's subductive mental implant words.
The reader thinks that one thing is under discussion (continental drift in this case) but then has unconscious doubts planted in his brain (rather like the pictures of evil demunzz they put in the pictures of happy smiling people listening to Jesus in first century drag.)
"CONIT" - this part means the gofor is to be conned by what he is reading into seeing the WTBTS as the ones who are really in the know.
"NENTIAL" - the WT here uses a "complementary hypnotic completion effect" -
They often brag how they have EXPOsed false religion. Here they claim to EXPOse false science. The reader unconsciously links this to NENTIAL, and the limbic system takes this as a message that their doubts in worldly science will increase exponentially, like the sea floor ridges.
It is so good to be free of Witchtower pseudo logic, isn' t it?
