Have you ever wondered where the world’s water came from?
When you look at a satellite image of the Earth, it’s largely covered by water, in fact, 70% of our planet’s surface is water. But where did all that water actually come from?
A fascinating episode from BBC Sounds’ CrowdScience investigates this very question: Where did Earth’s water come from?
Listener Bill from the USA wants to know, and presenter Caroline Steel sets out to find answers.
Consider this: Earth’s oceans contain approximately 1.3 billion cubic kilometres of water. But how do scientists even measure such an enormous quantity? And what about all the water we can’t see – the water hidden deep within the Earth itself?
Was water present when our planet first formed, or did it arrive later? Could comets have delivered our oceans from the depths of space? Or perhaps the answer lies in volcanic activity and ancient rocks?
The episode speaks with experts including Assistant Professor Muhammad Abdul Latif from the United Arab Emirates University, who helps unravel when water first appeared in our universe and traces its remarkable journey to our planet.
Whether you’re simply curious about the water you drink every day, or fascinated by the bigger picture of how our life-sustaining planet came to be, this episode offers compelling insights into one of Earth’s most fundamental resources.
