Question 7: What might be some implications of Robert Hazen’s experiments
Angelina_Jolie [31]

Answer:

Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020) .

Explanation:

Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.

You can read these articles that are certainly clarifying in the description of his experiments and discoveries:
