Earth has an abundance of water at its surface (and even more within its interior!), but where did all Earth's water come from? In this video, I cover all the hypotheses regarding the origins of Earth's water and how we study the potential sources of Earth's water and how much they may have contributed using isotopes! Hope you enjoy ;D
