The expanding or growing planet theory has always intrigued me and there have been many people who refuse to consider this as a possibility of why our planet is the way it is. i think the theory is sound and it just makes sense after you see how the continents fit together perfectly. this scenario also looks convincing with our Moon also.
Expanding Earth - Wikipedia, the free encyclopediaProponents of an expanding Earth hypothesis claim that the explanation for the position and movement of continents and the appearance of new crustal material at mid-ocean ridges is that Earth's volume is increasing. Modern scientific evidence does not support this idea, rather plate tectonics is almost universally accepted as correct. The small number of proponents of an expanding earth claim that the continents drifted away from each other because of further expansion at the rip-zones, where oceans currently lie. This contradicts the scientific consensus plate tectonics theory by stating that significant destructive plate boundaries do not exist.

if this theory is true , i wonder if there are planets in our own solar system that have water under the crust and will eventually expand and look similar to Earth ?
