As I recall (My dad was a strong believer of Velikovsky's theories) The proposal was that some mysterious "electromagnetic" forces were the cause of the effects on Earth.

Subject: Re: Venus?
I think Velikovsky's idea was that Venus was somehow ejected from Jupiter,
bounced around the solar system for a while, then settled into its present
orbit. Presumably at some point Venus approached Earth and exerted its
mysterious torque, then left. I suppose conservation of angular momentum
would let Earth start rotating again.
If I recall correctly, he also ties this into the rain of manna and several
other biblical stories.
