Meteorites, volcanic eruptions, and ancient rocks all contain valuable information about the composition and conditions of the early Earth's atmosphere. Meteorites can offer insights into the materials present in the early solar system, including those that may have contributed to Earth's atmosphere. Volcanic eruptions can provide clues about the gases released into the atmosphere throughout Earth's history. Ancient rocks can contain trapped gases or be formed in ways that indicate the atmospheric conditions at the time of their formation.

Scientific evidence indicates that Earth had cooled sufficiently by around 4.3 billion years ago for water to start accumulating. This is a key point in Earth's early history, marking a transition towards conditions that could eventually support life.

Question 9

&#8203;Until the early 1800s, scientists believed that molecules of life could only be made _____.&#10;A) &#8203;by prokaryotes&#10;B) &#8203;by organisms with RNA genomes&#10;C) &#8203;inside hydrothermal vents&#10;D) &#8203;by protocells&#10;E) &#8203;inside living organisms

Accepted Answer

Until the early 1800s, scientists believed that the complex molecules necessary for life could only be synthesized within living organisms, a concept known as vitalism. This belief was challenged and eventually overturned by the synthesis of organic molecules from inorganic substances, demonstrating that life's molecules could be made outside of living organisms.
