Actually, I think that whole discussion is in his “Earth In Upheaval”. :’)

Yes, Worlds in Collision was his first book, which set the stage for some of his later theories, such as an explanation of the numerous mammoth carcasses frozen in the Alaskan & Siberian permafrost.

EARTH IN UPHEAVAL

In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner.
Inspite - or even because - of the disgraceful hostility, provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing.
Earth in Upheaval - a very exactly investigated and easily understandable book - contains material that completely revolutionizes our view of the history of the earth.
For all those who have ever wondered about the evolution of the earth, the formation of mountains and oceans, the origin of coal or fossils, the question of the ice ages and the history of animal and plant species, Earth in Upheaval is a MUST-READ!

Immanuel Velikovsky explains this in an intriguing and controversial book, Worlds in Collision.

It was published in 1950, before the age of space exploration. When we finally got out there it was discovered that a number of his suppositions were either dead on or very close. It is worth a read.
