The Amazing Life of Sand | Deep Look


Sand is a time capsule. Every grain tells a story. Sand can be anything that’s been worn down until it’s reduced to some tiny essential fragment of what it once was. It’s a technical term. Bigger than sand? That’s gravel. Smaller? Silt. Go to beaches across the world and you find sand that looks completely different. If you could take a single grain of sand from every beach you would have a history of the world pinched between two fingers. A hundred years ago, a pebble chipped off a slab of granite in the Sierra mountains. It was dragged by the current of the Sacramento River through the Delta, out the Golden Gate and onto the beaches of San Francisco. Sometimes, sand is a graveyard, full of dead bodies. This is the shell of a tiny foram, a single celled organism whose skeletons litter the bottom of the ocean. This sand? Almost entirely coral. This one, shards of lava from a Hawaiian volcano. This tiny nugget of quartz tumbled down the waterways of Appalachia, all the way to the beaches of Florida. By the time it got there, it had worn down to the consistency of sugar. Time takes a big thing, and makes it small. But sometimes the opposite can happen. Behold, ooid. The only sand that accretes rather than erodes. Think snowball effect. A tiny speck of brine shrimp poop is tossed and turned on the ocean floor accumulating minerals like calcium, until it’s a grain of sand the size of a pin tip. Sand is a snapshot in time, a stopping point between the very big and the very small, the landlocked, and the oceanic.

  1. I grew up playing on the beaches of the western coast of Florida. The diversity of sand there is incredible; in Naples, just above the "border" of the Everglades, the sand is coarse and mixed with dirt, like brown sugar. But only 100 miles north of Naples, in Sarasota, the sand is pure white and ultra fine, like flour, and the sand never gets too hot to walk on because the grains' surface area is too small to retain heat from the sun.

  2. 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!

  5. Goes to the beach
    struggles to get only a single grain of sand
    “Hello there little fella. What’s your story?”
    Sits quality holding the grain of sand as his surroundings play along peacefully. Completely derpy and listens to grain of sand for few minutes and puts it back.
    “That a nice story!”
    Grabs another grain of sand.
    “Now what’s your story?”

  6. "So the next time you're walking on the beach, enjoying an hourglass, or making cheap, low-grade windshields, think where we'd be without… sand. Sand! Sand! Saaaaand!"

  7. Now you went and made me fascinated by sand. And now I feel compelled to go and collect sand from beaches. Also I’m feeling intense regret that I didn’t collect any sand from the beaches I’ve been to since I was born.
