Instead of seeking for the "light blue dot" mentioned by Carl Sagan when hunting for Earth-like worlds surrounding other stars
The near-balance of land-to-water that has allowed life to flourish on Earth may be quite uncommon.
Tilman Spohn and Dennis Höning investigated how the evolution and cycles of continents and water can influence the formation of terrestrial exoplanets.
"On our home planet, we Earthlings appreciate the balance of land areas and oceans."
It is tempting to believe that a second Earth would be identical to ours, but our modelling results indicate that this is unlikely.
The computational simulations developed by the scientists imply that the average surface temperatures would not alter significantly.
Climates would be colder, drier, and harsher in continental worlds with fewer than 30% oceans.
