Researchers suggest the rocky Earth we know today is a result of extra-terrestrial impacts from billions of years ago.
A new study has found that plate tectonics were triggered by intense bombardment of meteors – transforming the hot, primordial mushy surface into the present rugged landscape.
The team discovered distinctive layers of round particles condensed from rock vaporized during an impact suggest the Earth experienced a period of intense bombardment about 3.2 billion years ago – similar to when first plate tectonics appeared.

Why Aliens Might Smell Really Bad, According To Expert
Clara Sousa-Silva, a molecular astrophysicist at the Massachusetts Institute of Technology who focuses on detecting exoplanets, said during a panel held at the International Astronautical Congress in Washington, "It's probably something that's going to be a slow discovery, not like the little green humanoids arriving here on Earth scaring everybody."
She added that the discovery is probably going to take a long time, but she thinks that a slow discovery could make it easier for people to process it and its significance.
Holiday gift guide for science books: Find your way through parallel universes in print
The Number of the Heavens: A History of the Multiverse and the Quest to Understand the Cosmos: Veteran science journalist Tom Siegfried traces the history of humanity's musings about other worlds and other universes from Epicurus and other Greek philosophers all the way up to the debate over the inflationary universe, superstrings, branes and other out-there concepts.
