Caltech Reveals Earth's Formation Secrets
A study from Caltech reveals that the early Earth formed from hot and dry materials, suggesting that water arrived late in the planet's formation. By analyzing magmas from different layers of the Earth's interior, researchers found that the early Earth lacked volatiles, including water. This discovery challenges previous theories of terrestrial planet formation and has implications for understanding the building blocks of other planets in the solar system. The study highlights the importance of exploring inner planets like Venus and Mercury to better understand how terrestrial planets, including Earth, were formed.
