Explanation:
Detailed explanation-1: -Meteorites are shards that have broken off of larger objects such as comets or asteroids, and it is thought that asteroids and comets from the outer reaches of the solar system may have left water on nascent Earth after impact.
Detailed explanation-2: -Scientists predict that the water in Earth’s oceans came from water-carrying bodies in the early solar system that collided with our planet, similar to today’s ice-rich asteroids or comets.
Detailed explanation-3: -Newcombe and her co-authors discovered that, contrary to popular belief, not all outer solar system objects are rich in water. This led them to conclude that water was likely delivered to Earth via unmelted, or chondritic, meteorites.
