what is the most likely origin of earths water based on current scientific hypotheses? a) exclusively from comet impacts b) only released from volcanic outgassing c) a combination of volcanic outgassing and extraterrestrial impacts d) photosynthesis by early marine organisms

Answer

Brief Explanations:

Los científicos creen que el agua en la Tierra proviene probablemente de una combinación de gases liberados por volcanes (outgassing volcánico) y impactos de objetos extraterrestres como cometas y asteroides, que trajeron agua al planeta durante su formación y evolución. La fotosíntesis de organismos marinos tempranos no es la fuente principal de agua inicial, y no es exclusivamente de impactos de cometas o solo del outgassing volcánico.

Answer:

C. A combination of volcanic outgassing and extraterrestrial impacts
