"The hypothesis posits that the Earth is growing"

"The Expanding Earth theory has similar benefits, with the upside that it doesn’t require the land to start on one side of the globe or for subduction to occur. But has the obvious downside in that it requires the Earth to grow in size – which on the face of it makes no sense."

"Growing Earth (Expanding Earth hypothesis) suggest that instead of the supercontinents theory the planet has expanded from its original supercontinent that was the whole Earth's surface, or, fitted together better on a planet with a smaller volume.
Over the centuries there have been a lot of theories about a hollow earth and an expanding Earth and how or what processes could cause a planet to grow."

"However the Expanding Earth hypothesis failed and fails to provide a convincing mechanism to explain the supposed increase of earth´s mass or volume over time."
