The outside-in model states that most of earth's water came from meteorites or comets. what evidence would support this model? a. finding multiple comets in our solar system that contain water b. observing that a single volcanic eruption increased water vapor levels c. multiple observations of water bonded to minerals in earth's mantle d. finding that water extracted from a single comet is not similar to ocean water
