Question

According to the article, why did scientists come to the conclusion that the solar nebula played a role in the formation of Earth's

water?
O
The solar nebula are clouds of gas and dust left over from the formation of the sun, and the clouds were
filled with water that came to Earth.
O
Samples from deep within the Earth did not have the same deuterium levels as asteroids do, leading
scientists to look at solar nebula gas.
Scientists decided the solar nebula was a possible explanation after ruling out the idea that asteroids
and comets affected the formation of Earth's water.
O
The chemical signature in the oceans' water matched better with the chemical signature found in the
asteroids that came from the solar nebula.

Answer 1
