Where Earth's Water Originally Comes From | Naked Science | Spark

Water is one of the building blocks behind the miracle of life on earth. It covers 71% of our planet and forms a key part of our daily lives. Where this important resource came from, however, is a mystery. Why does nobody know for sure where our water came from?

Ill save everyone 45 min. Where does earths water come from??? Your guess is as good as theirs, they don't know.¯\_(ツ)_/¯ The end.

An awesome video for encourage my students to love science by watching scientists at work practically implementing the scientific process. A must-see for teachers Highly recommended. Thanks Spark!

We are treating this most precious miracoulous life sustaining resource with utter contempt.

commercials make me stop watching..i pay to not see them now they show up in videos..bs

Water molecules begin to disassociate above 3, 000 C. Much of the earth's mantle is far hotter at 3, 700 C. So the water in the lava being sampled for it's heavy hydrogen ratio could have recombined into a different ratio at any time or any place under the right conditions. Probably why the scientist was interested in sampling Iceland. The ratios are likely somewhat different in every sample location because of this making it impossible to conclude anything.

Water is a mineral produced every time hydrogen oxidizes.
It's ubiquitous throughout the solar system. (Universe)
How a planet or moon could lack water is the extraordinary puzzle.

Some idiot left a tap (faucet) running for 3 million years.

This is a great video asking more questions we still need to answer. Excellent!!! Alain Faber

So 60% of me is 4.5 billion years old

Haileys comet ☄️ looked like a fuzzy 🥔 when it passed by 😂

The only thing that makes sense is via chemistry: an acid + an alkali results in water & salt, basic chemistry. What on Earth isn’t chemistry?

[coffeetalk]

My imaginary friend done it. He's the goodest bestest fix all answer I've ever known 🤣

[henryvoigt]

Great program. And if commercials are bothering someone, don’t forget that they pay so you can watch this excellent video for free.

When I was a young teenager, I thought our water has made in advanced for us by the Nature, before dinosaurs, then humans. Thanks you for the water science clip.♥️♥️

This video is a testament to the power of scientific inquiry and collaboration. The journey it takes you on, from the formation of our solar system to the birth of Earth and beyond, is nothing short of awe-inspiring. A fantastic blend of education and entertainment that leaves you with a newfound appreciation for the wonders of the cosmos!

The information train left a long time ago and is never coming back !!! 😅😂😅😂😅😂

[Astropaesan]

Spark, as a hobby astronomer, I respect what you do. Great production. You do terrific work, in an age of shows that are outright lies and mistruths.

Thank you. I know that I can count on Spark for honest, trustworthy programming.
Keep up the respectable work!

Well done!

Thea was a ice world.. that delivered the water.. 🤔

[nunyabuziness]

The honest answer is we dont know we only guess

May be earth had 0 degree tilt earlier forming massive ice caps. When something collided, it tilted by 23.5 degrees and part of ice caps melted to form oceans.
