Calcite is more stable than aragonite. Aragonite is metastable, meaning it will slowly change to calcite over time -- much the same way a diamond will eventually become graphite.
WOW omg that EPICAL
I had a beautiful chunk of aragonite as a kid. They now show aragonite at mineral shows as UFO rocks. Thanks for rhe neat video !🐌🐚
thats called polymorphism - a mineral can exist in more than one crystal form under certain conditions
Your video explains "what" seashells are made of, not "how"..
nemesis Right? So does it poop it out? Spit it out? Secrete it?
Thank you. I was wondering how people so smart could make such a stupid mistake.
nemesis exactly
Channel is called reactions for a reason. It did explain how it was formed, I’d imagine just not in the way you were expecting. I’d recommend nature watching channels for that instead of a chemistry one.
💯💯💯
How are they made tho
yeah. howw?
@@kleingomez9724 probably by clams and hermit crabs
fr
Nature is very powerful and smart
All creations have a Creator my friend.
Too much chemistry.... I just wanted to know HOW
Ikr
How do you have sex with a shell?
@@trixyb6869 Now you’re asking the REAL questions.
@@paintballfloridaman1997 truly
Theres barely any actual chemistry here
Great video. My only critique is that this seemed more of a "What is a seashell, really?". I think a better way to focus it toward how they are made is to include where the calcium carbonate may come from in order for the creatures to put it to use
Would love this video if I was a biology major, but now I must find a video of how seashells are made instead of what they're made of
Me : my friend is dying how do I stop her heart attack
Her: wElL WhEn tHe fLoW Of thE OxyGeN rIcH-BloOd iS BlOcKed
Me : kejadgnTDZWNhikoD Just stop shes dead already
This video should be called What Seashells are Made Of, not How Seashells are Made
Great great, but how are seashells made?
www.scientificamerican.com/article/how-seashells-take-shape/
This articles says how.
@@sel4205 Great job.
You should start a youtube channel, where every video you post is just a picture of a link that answers the question in the title.
@@MisogynyMan lol
Misanthrope Man THANK YOUU!!!
I still don't know how.
ive been collecting seashells for my collection is so big i keep them scattered on all the beaches around the world. If you've ever been to the coast you might have seen some of them
😆🤣 I've seen some of them and I must say you have a beautiful collection! I collect rocks and like you I keep the majority of them scattered across the earth for all to enjoy. Although it's entirely possible that my little acre of ground, (yard, shed, barn, drawers, buckets, bags, jars, pockets, even my truck) is slightly more densely packed than the rest of the earth lol.
This video was more why you can't draw on the sidewalk with a seashell, instead of how the shell is made. Like how does the Bicarbonate get in the organism and converted into Calciumcarbonate?
Seashell chemistry sounds like it holds many discoveries to come, it seems like a great place to look having so many million years of evolution.
If there is a design, there is a designer. If there is a plan, there is a planner. And if there is a miracle, there is a God. We recently got back from the ocean. We often stepped on shells because there were so many. I didn't realize before watching this, while stepping on the shellls, how absolutely amazing and miraculous these creatures and their shells are. I know everybody has their own opinions and perspectives and I respect that. I'm not interested in arguing. But I am compelled to say that I definitely believe that there is a God... a designer and planner behind all of this. Sure, there are a lot of questions... and so much that we don't understand. But I believe it's hard to deny that these shells are put together with such intelligent design. Just something to ponder. I love science and technology and I think it's great that we're learning so much. It seems like the more that we learn about the world and universe around us, the more evolution seems to not be a very believable explanation for all of this. And again we're just talking about seashells. Check out a video on our eyes. It's overwhelmingly mind-boggling.
i was collecting shells once and showed my dad one on the classic flat ones and he said, “i wonder what used to live in that one” and i just looked at him and said, “what” then realized that seashell don’t just appeared
Why are shells different shapes? What determines their geometry?
That’s the kind of thing I want to know, and can’t find anywhere - maybe it’s a mystery to science. How is the outside so glossy and intricate and spiraled outward over time? What’s it look like at the beginning? I’d love to see a time lapse from squishy creature with no shell to the beginning of secretion through completed large shell..
I have googled this many times and felt like I still didn't have an answer but this came close. Thank you👍
Woah! I love at the beach and I've never asked where they come from but I am sooo glad I Googled it after seeing a video on tiktok of a lady opening up some sort of pods and showing many baby seashells coming from them. Biological science is my favorite science ever so I'm definitely going to be doing more research on this topic because I am absolutely mind blown!
SCP-173, also known as The Sculpture, is a creature from the SCP Foundation, a fictional organization that works to keep anomalous objects, places, and creatures secret from the rest of the world. SCP-173 is an animate statue made of concrete and rebar, painted with Krylon brand spray paint.
Old creepypasta stuff, nice
For all the people asking “bUt HOw ArE tHEy maDE???” Here: 2:42 you must have missed this. But let’s just be honest, you probably watched the first 10 seconds, didn’t get the answer you were hoping for, or simply didn’t understand the information presented, and immediately went to the comment section to post the exact same comment that has already been posted 50+ times.
Although I appreciate the comments that are trying to guide other confused viewers, that time stamp really only explains how chitin is formed. The video (which I watched all of before going to the comments) explains that shells are mostly made of calcium carbonate.
I think what most people (myself included) are feeling left untaught is the actual process that adds calcium carbonate onto the shell structure. In what direction does it form? Spirally or does it build on the existing spiral? Does the mollusk add to it from its skin? Does the calcium get pulled straight from the surrounding water? Etc.
If Paramount Pictures does a Freddi Fish film, the Paramount Pictures logo will have seashells replacing the stars. The seashells make ocean sounds as they fall from the sky and tread the water as they fly to the iconic mountain.
If you know that seashells are made of basically the same stuff as chalk, you might have wondered why chalk is crumbly but seashells are super tough. This week on Reactions, we explain: The secret’s in the biochemistry.
But how are they made over time by the little squishy creature?
Wow such a good explained video , i really love how you explain it , so usefull video
And even if i am 5th standard i can understand what sea shells are made up of ....
THANK YOU SO MUCH for this video 🤩🤩🤩
Went down a hole to find out how bivalves make their shells and the answer seems to be “no one knows but here is their chemical composition and molecular structure”
2:07 you can't say that
Mah Nacre
Mikey Alexander It’s a joke niceguy
This should be titled why seashells are tougher than chalk
But how??
At 1:59 you have Colt Cabana with a seashell for a head. Just needed to point that out.
wow,seashells contain MIN YOONGI......lol
Thank you for the information .
POV: you are here by luigi
After this non-educational video, one can only assume that they make the shells by carrying some kind of molecular rearranger like the type Ultron uses to move around in his adamantium shell.
Dissolved carbon comes from dissolved CO2, meaning the CO2 in the oceans is the building block of shells, not something that destroys them.
Great video thank you, the only think I would mention (because I live there) is that those are not the cliffs of Dover, they are cliffs in Sussex called ‘The Seven Sisters’ and ‘Seaford Head’ a beautiful part of the UK. Sorry to be pedantic! Love the video though!
Yeah sea shells are tough right? Is that why I can grab it with my finger and thumb and press lightly and the shell shatters?
I couldn't think of anything but Chitlins.....it's just 1 very important letter.
Love Seashells!
Too technical. It doesn't answer so many questions. Do the molluscs who make these shells die first, or abandon their shells on the beach and walk away? How do these shells find their way to the beaches?
Lovely video!
Never told me how them form
So carbon capture tech could be combined with sea shell tech to sequester the carbon cheaply?!! Need a video exploring this possibility.
Mexican Army Day is celebrated every year on February 19. It commemorates the formation of the Mexican National Army in 1913.
I still haven’t understood
1:18
How do they form show a video of that...sheesh not the science mumbo
up down, side side, diagonal diagonal, left diagonal, rightiish side up and . down, lftside up and down, bottom side, side to side ,up side, n side to side
Nacre what now??
You can def. break sea shells without much difficulty... I do it to look at the shiny part inside
This is not the video that I was searching for. Misleading title.
HOw dammitt..how?
I just lost 4 minutes of my life. I don’t care what they’re made of, I want to know how they’re made
I want to know
Seashells and other types of shells are the bearers of an important cosmic-divine imprinting, for their perfect shape. Check on yt: " Spirals and shells, the golden section pattern in Mother Nature"
sam enjoys ball
you didnt answer HOW SEASHELLS ARE MADE!
This didn't help me make my rust base better
How do they look the same?
she sell sea shell by the see shore
What up my Nacre!!!!
God made our seashells, just like everything else in the world. It’s not a question how we were here in the first place. God made everything we have.
My brain keeps saying "Aragornite," lol.
son of Arathornite!
ok but like HOW
"Morpheus, Walruses
Seashells by the Seashorpheus"
Ok but you never explain how are they made!.
Ok if hermit crabs have to find bigger shells,where are those shells coming from?
D R
They take over shells who’s creatures have died. I saw one video where a hermit crab actually fought another, more dangerous creature, for an empty shell...and won! Unfortunately, due to all the pollution hermits will make their homes out of anything-cans, plastic bottles. I’ve seen it, it’s sad.
They get their shells from marine snails.
I like the video
She sells sea shells on a sea shore
But the value of these shells will fall
@@LeaveMeAloneFBI Due to the laws of supply and demand.
BOOM BOOM
I still don’t know how they’re made
Hey my name is sunny and just wanted too say something about that is way vary pretty ❤
Wow Amazing...Oceans are one of the wonderful place in the world. Where there a lot of 😍 beautiful shells 🐚!!! Which i have millions of collections too 😊. This was a great video. So inspiring.
Can't we produce in laboratory
@2:08 wait wat
Cool 😎
Still havnt found an answer!! SMH 🤦🏻♂️
Is it possible!!!ok then can you make a diamonds
Wow you made that so boring!
This was a good video
What🤦🏻♀️
Do PEARLS !
oOoo good call.
I loved 🥰 the voice of speaker ❤️❤️👍👍
What
This does nott awnser my questions at all
lol I sell this stuff my guys
Why just shells why limit yourself? She sells sea shells sell oil as well!
You sound like reading fast rather than talking and explaining.
Grace to Allah who created all this and made moluscus and mussels know how to be a better architects than man
chack is calcium sulfate
Please change the title
Who else came here after that one Tik tok
yur🤙
You actually “digressed” the whole video?
Down thumb 👎🏻
Awesome!
I’m gonna get rich off of sea shells
I'm already running for president
Can’t stand the uptalk accent. Too excessive it’s distracting.
I agree.
How not what , come on you are not atupid
The 12 persone to like the video
I learned nothing!
I think the inner side of oyster is made of calcite, not aragonite.
❤❤❤❤❤❤❤❤
Instructions unclear, broke my jaw trying to taste that 5% sugar
What an amazing accident. /s
