---+ How does sand form?
Sand can be anything that has been worn down until it’s reduced to some tiny, essential fragment of what it once was: a granite pebble from the mountains; coral from the sea; obsidian from a volcano; even skeletons of microscopic sea animals. It's also a technical term. Bigger than sand, that’s gravel, smaller? Silt.
By studying the composition and texture of sand, geologists can reconstruct its incredible life history. “There’s just a ton of information out there, and all of it is in the sand,” said Mary McGann, a geologist at the United States Geological Survey in Menlo Park, CA.
McGann recently took part in a comprehensive research project mapping sand’s journey into and throughout San Francisco Bay.
Patrick Barnard, another USGS geologist who helped oversee the project, said that it will help scientists understand how local beaches are changing over time. In particular, Barnard wants to understand why beaches just south of San Francisco Bay are among the most rapidly eroding beaches in the state.
From 2010-2012, Barnard and his team sampled beaches, outcrops, rivers and creeks to track sand’s journey around the bay. They even collected sand from the ocean floor. The researchers then carefully analyzed the samples to characterize the shapes, sizes, and chemical properties of the sand grains.
Barnard said the information provides a kind of fingerprint, or signature, for each sample that can then be matched to a potential source. For example, certain minerals may only come from the Sierra Mountains or the Marin Headlands.
“If we’ve covered all of the potential sources, and we know the unique signature of the sand from these different sources, and we find it on a beach somewhere, then we basically know where it came from,” explained Barnard.
And those species aren’t the only things finding their way into the sand. Manmade materials can show up there, too. McGann has found metal welding scraps and tiny glass spheres (commonly sprinkled on highways to make road stripes reflective) in sand samples from around the bay.
“All of these things can get washed into our rivers or our creeks, or washed off the road in storm drains,” explained McGann. “Eventually they end up in, for example, San Francisco Bay.”
By piecing together all of these clues - the information found in the minerals, biological material and man made objects that make up sand - the researchers ended up with a pretty clear picture of how sand travels around San Francisco Bay.
Some sands stay close to home. Rocky sand in the Marin Headlands comes from nearby bluffs, never straying far from its source.
Other sands travel hundreds of miles. Granite from the Sierra Nevada mountains careens down rivers and streams on a century-long sojourn to the coast.
In fact, much of the sand in the Bay Area comes from the Sacramento and San Joaquin rivers, with local watersheds also playing an important role in transporting sand to the beach.
Although this project focused on San Francisco Bay, the same techniques could be used to study other coastal systems, he added, revealing the incredible life stories of sand from around the world.

#deeplook
if you think about it, if you throw the sand or move it somewhere else, it could end up miles away from where it was going to end up before which makes *you* part of its story
Diamond Miner Animaniac Very true....lol!!!!!
*True*
And people still say our actions don't have consequences....
weow
Tlactl how to be in a book without asking the author
Is sand called sand because it's between sea and land?
mind. blown.
Deep Look Ayyyyyy thanks! (But wow omg sand sea land-) and then we all exploded
*@Sycamorre* ___ Good point...but indeed....it's interesting to figure out how things got named . Often the sound a collection of letters makes, might indicate the object...wonder how stone age man did indicate "sand".
In the major languages it starts with an 's' or a 'z'..Germans call it "sand" also , yet the French call it "sable"...The Spanish for some reason call it "arena"..???? Yet the peoples mostly associated with sand ,the Arabs (and Dutch), call it "zand"...
Deserts are just dried up oceans, people find sea fossils there all the time
WHAAAAT?!
I want to know every grain of sands story now .-.
Me too! 😂😂
Scarlet Grace Victoria You may have too much time on your hands.
okay

This video makes me want to start collecting sand ._.
sameeeee...so odd
Me too... 😂😂😂 That's why I'm wondering if it's allowed to bring sand at the airport...
That's illegal in some beaches like boracay
Stellar footage. This concept is fascinating, and I'm
So
Glad I found your Chanel. Seriously, gorgeous stuff. The kind of artful education I'm looking for.
We are happy to oblige, Kendal. Tell your friends!
@@KQEDDeepLook no
The natives were right. Stories of life are written in everything in existence. In trees, in coral, even sand. Layers of dirt are like piles of paper filled with information of the past when you look at them through the lens of an Archaeologist. Itś really fascinating how the most simple and seemingly insignificant things could hold so much significance.
It's*
@@lennyface2586 yeah yeah smart freak can't u just appreciate his comment.
Are you here just to lecture other grammar.
I love how you phrased it all❤❤❤❤ It really is amazing! I wonder how amazing it was also for our ancestors to feel more connected to them too every existing living organism❤❤
Anakin Skywalker made 42 separate accounts to dislike this video
what
{feather_cloud} because he hates sand it’s messy and gets everywhere
@@amazely5205 ok
*intense inner pain*
Well ive been to some philipine beaches and and the sand was really different and some sands are made by the stone fish
Great, now I'm looking up "brine shrimp poop".
now i am too because if you
veranet99 thanks a lot
How does this channel not have a million subscribers? The quality of videos surpasses most of the naturalistic channels. Rivals that of BBC and Discovery.
Thats what internet is today
The Humble Geometric Figure of Doom IKR
Such a shame it's no longer actualised as well... it's so hard to find good content nowadays.
Aged like wine
I'm starting to wish these little shorts were in fact the intro to multi-hour long documentaries. :( I want to learn morrreeee
Really enjoying the high quality videos, it reminds me of the light reading I would do when I was a little kid. I used to read so much about random animals and facts about the nature kingdom. If I could suggest a topic, I'd love to learn more about the origin of household cats, and their behaviour to use litter. Did they all originate from deserts?
Cats bury their poop in whatever is available on the ground, dirt, sand, mulch, leaves, etc. Thats why they go for litter so well.
@ekul Z its their natural instinct is why, just like i said above...
@@Goldi-Luc and the question is, why? Why is that their natural instinct? Why is their natural instinct to burry their feces? Do they use it as fertilizers to grow plants for their sheep who they'll then slaughter as meat? Is it relatated to the so-called first housecats, Egypt? So many things to know.
@@anotherdayanotheranimation my personal belief is God made animals to have their natural instincts.
@@anotherdayanotheranimation to hide their scent, so as not to be found by the scent of their poop.
Why am i so amazed at sand!
Your icon reflects your comment perfectly
MoondayBlue because your life is as insignificant as a grain of sand.

Every now & then I find an interesting new channel. This was one of today's :)
Are you quoting William Blake? "To see a World in a Grain of Sand"
BACKGROUND MUSIC RIP OFF BUSTA RHYMES MUCH??
*I HATE YOOU!!*
Somehow, I read that as
Tales of earth and air, water and fire...
Long ago, the four nations lived in harmony~
Finally, a channel that focuses on the small things in life, and explains the beauty of the things we don't see everyday. These videos are short and simple, and are packed with information that I can enjoy. Thank you for your effort, and I suspect that this channel will start booming in popularity any time soon.
You are welcome, John.
Producer: we need music to help convey feeling for sand/silt
Composer: ever play pikmin?
Producer : Brilliant!
Deserves more subscribers than jake paul
oh wow i need to start collecting sand on vacations......
Watch out, in some places it's illegal!
Excuse me, what?
I think the team at Deep Look learned in the hard way. :D Thanks mates!
I don't like sand. It's coarse and rough and irritating and it gets everywhere...
These videos are perfect. I can't believe I missed this channel up to now.
+M. Utley Welcome! We hope you enjoy our channel!
Are "shards of lava" the same thing as shards of obsidian?
Obsidian is a rock that forms when lava solidifies, so yes. However lava can also become many other types of volcanic (igneous) rock, so those shards of lava might include both obsidian and other rocks.
@@mikkicarr5717 Yeah but don`t forget to bring a diamond pickaxe.
Anakin disliked this video
I feel like this channel can make a pile of dog faeces on the street seem incredible
Some of these bits may be deceased Avengers
Too short, could easily be 4 times as long.
Im gonna start a Band called The SAND...
Then imma sing a song on the story of the Sand in my Hand ...🌅🌅🌅⛰⛰⛰🚤🚤
This is just beautiful, thank you for doing this.
Every of Deep Look videos is just like...3 minutes but it gives you just a plethora of knowledge
watching this baked omg is so amazing this channel is so amazing and mesmerizing gotta type faster so i can watch more videos, life if your baked or reply happy smoking
You guys should take a look at the unique qualities in snowflakes!!
This channel is so underrated! These videos are just perfection! I enjoy so much watching them
And here was me thinking sand is only SiO2, and was about to ask if every sand is a really petite Quartz crystal O.o
Fascinating.
never thought sand could be so interesting..keep up the good videos guys
Deep look can I suggest? I wish to know the cycle of a snowflake from this channel.And thanks for keeping us amaze every time.
Thanks for the idea!
“I don’t like sand. It’s coarse and rough and irritating and it gets everywhere."
I don't like sand. It's coarse, and rough, and irritating, and it gets everywhere.
"Time takes a big thing and makes it small" it's very deep if you think about it.
I thought the same - thinking about the problems of life
My Friend Anakin did not like this video.
Soooooo…… if you throw rocks into the sea your get sand after thousands of years?
Anakin: Cool story, still sand
High quality videos like this are becoming rare. Amazing job!
Some sand is shrimp feces? I need to watch where I'm stepping!
This is the best video amongst your video i've seen till now
Exactly 666 likes. Coincidence? I think not. BURN THE SAND!
great video great looking sand!!
Hmm, so if sand comes from different places like mountains and sea creatures, is the video from MinutePhysics about sand wrong? They said sand is made in the formation of rocks and is the Silicon Dioxide that forms in the cracks and crevices of other bigger rocks, making sand a mostly uniform chemical composition and size. This video seems to suggest that sand's chemical composition varies, containing calcium and other elements, and the size is how it is categorized not a product of the sand's creation.
Wow!! Thanks I've always wondered where sand come from..
I don’t like sand. It’s rough, course, and irritating. AND IT GETS EVERYWHERE!
"sometimes sand is a graveyard full of dead bodies" that took a turn. Huh?
Wish these were longer
Majority of the videos are fantastic! First rate. tamd hey could even stand to be a wee bit longer. The female narrator has a lovely listening voice, my kids agree... Good Luck!
Thank you, Anne! So glad you and your kids are enjoying the series! Any favorites?
Did you hear about the battle of the sand and ocean?
It was tide, haha! Get it? Ha!
Ok imma gonna leave now
I was just settling into this videoe and it finished! Shame! I want to know more. Thank you for what we have received anyway!
Ok- but why do i want too eat it so bad
Florida's beach sand is definately the best out of all of these, hawai's volcano sands is a close second
Great video, Thanks I learned something new today.
I don't like sand. It's coarse, rough, and irritating... And it gets everywhere.
*eats sand* i have history *inside* of me
I seriously love all your videos. I learn so much everyday from watching them! Great quality, great content.
Thank you!
i hate going to the beach. why? because of sand. why do i hate sand? it gets everywhere even if you try to wash it of some are still on you
I don't like sand. It's course, rough, and irritating, and it gets everywhere.
So.. In short Building Castles out of Sand is also Building Castles out of Fish Shit?
so a sandbox can be a graveyard box?
little jimmy be making sand castles out of dead animal carcasses
I hate sand. It's coarse and rough and gets everywhere.
Unlike this channel.
I don't like sand. It's coarse, rough, irritating and it gets everywhere.
subsribed,, :)
Pratidina W me too.
I want to collect sand from every beach I visit in my life
I don't like sand. It's course and rough and irritating and it gets everywhere.
Honestly, it's everyday phenomena like this that give me a reason to keep living. Even if life seems unbearable some days, I find solace in knowing how wondrous the natural world I live in is. If I died, I wouldn't ever be able to watch a grasshopper groom itself again, or look at tiny fossils under a pocket microscope, or eavesdrop on birdsong. Sorry for the sappy, semi-depressing comment, but it really does give me a sense of fulfillment and unbridled joy to pay attention to little natural things like this. Keep up the amazing videos; you guys deserve way more subscribers than about 452K!
Thanks, Almandine!
I love your videos, so interesting and well made !!!!
sand rocks! enter sand, man. rock sand, you don't have to turn on the red light.
i clicked because I thought the thumbnail was universal sandbox
If it's about sand, it's also about geology
You can learn the origin of each grain of sand, and sand from different places tells different story too
So glad I found your channel - some superb imagery. This is a beautiful insight into the sciences of our world!
The Yosemite story is incorrect. Anything floating into the MERCED River would then wash into the SAN JOAQUIN RIVER and into the SUISUN DELTA, further traveling into the SAN PABLO BAY, then the SAN FRANCISCO BAY (actually an estuary).
You're right, Yosemite feeds into the San Joaquin, not Sacramento river. The narration says the grain of sand originated in the Sierras which feed several rivers including the Sacramento and San Joaquin. Since we showed half dome in Yosemite we should have said San Joaquin river in the narration.
The lenses you use to get these amazing pictures are amazing. Very beautiful images. Thanks, Deep Look!
This series wins on all fronts. Beautiful, thoughtful, well-produced, perfectly narrated... . I will be sad when I finish the archive. Yay Public Media!
If y'all enjoyed this, I'd encourage you to take some Geology courses and learn a little more. It's amazing how much history is contained in the while crust of the earth not just sand.
I'm majoring in the subject in University as we speak, and it gets more and more interesting the more I learn.
They say “you are what you eat” so if i eat sand, i've become an historic person??
Obviously Anakin made 112 accounts to hate sand
Please never stop making these videos, this is my favorite channel 💗💗
i am in love with this channel.. i came here daily to see something interesting and wounderful
Damn sand particles. Scratching up our phones !
Wonderful! Thank you very much! :-)
I Loved the narrator's sweet voice too.. ;-)

I love the narrator's cute voice and the music together makes it sound so good!
best like/dislike ratio I've ever seen
Only deep look can make sand interesting. Keep up the good videos

-Yaaay!-
You're the best channel for natural education
Are you threatening me with the value of sand
The amazing life of sand is very bland.
It needed the theme: "Sand, Sand, Saaaaaand!"
In the thumbnail, I thought they were nebulae 😐
This was amazing to watch and the change in perspective is nice from other natural documentaries. How about follow up videos on dirt and rocks? :)
Why not just crush lots of rocks into sand?
I wonder where all the sahara sand came from.
Sometimes sand are parrot fish poop ;-;
