Briefly, describe the formation of Earth’s ocean. What will be an ideal response?
During Earth’s formation, gases trapped within the planet began to vent to the surface
through volcanic outgassing. As the hot vapors rose, they condensed into clouds in the cool
upper atmosphere. In addition, icy comets or asteroids colliding with Earth may have
contributed a portion of the accumulating water on Earth. As Earth cooled, outgassed water
began to form droplets and hot rains fell to Earth for millions of years forming a deep ocean.
