Accretion Theory

This theory proposes that by continual and steady accretions to the Earth by interplanetary and extra planetary materials, including rock and metallic bodies but also to a great extent water ice and other frozen liquids and gasses, the Earth has been increasing continually in size.



Continental drift as by Alfred Wegener    [ The Origin of Continets and Oceans, by Alfred Wegener (1915), translated by John Biram, Dover Publications, New York, 1966, page 19]

Wegner was one of the first to propose continental drift and plate techtonics but throughout his time line saw the plates drifting about an Earth of a constant (present) diameter.

Earth tectonics as shown in exhibits at the Museum of Natural History, New York City, (2004) also show continental plates drifting about a constant earth diameter.
