Explanation:
Detailed explanation-1: -The water we encounter today, it seems, must have been delivered long after Earth formed. Faced with this conundrum, astronomers realized that there are two ready-made sources: comets and asteroids, the solar system’s gravel strewn among planetary boulders.
Detailed explanation-2: -Multiple geochemical studies have concluded that asteroids are most likely the primary source of Earth’s water. Carbonaceous chondrites–which are a subclass of the oldest meteorites in the Solar System–have isotopic levels most similar to ocean water.
