How Do Glaciers Move?

[@besmart]

A question of glacial proportions? Icy what you did there.

That was some dirty snow

[@lilyhuang3677]

Hey It's Okay To Be Smart I love your videos :D So informative and the animation's like Kurseagast but BETTER. And the host looks cool... ;D

[@kiir0whei23]

I can hear ur voice Doc Joe! 😆

zbobhigh Maybe he could pitch a few more, but we might miss the drop.

[@andrewc3336]

AirborneSurfer This comment is absolutely brilliant.

[@AirborneSurfer]

Took 30 days for someone to get that. Well done, sir!

[@KQEDDeepLook]

Wow - those blues are incredible. Just curious, did you get to hear any of the amazing sounds that glaciers make? Such as the 'Bergy Seltzer?'

[@besmart]

Sadly, no! Just the "cronch cronch cronch" of my crampons

[@VoidHalo]

I've always wanted to throw rocks on a lake with a thin layer of ice in it to make those crazy bullet-like noises. I have to wonder at how many different ways large masses of ice can make extremely loud, and unusual sounds. I bet there are all sorts from glaciers rubbing on glaciers, glaciers rubbing on rock, rocks being broken up on a large scale. I'm sure just the way in which a glacier causes the ground to sink would make some weird noises. They're probably mostly infrasound from the size and time scales involved.

[@Pleaseremainshyam]

Every time I see your video in my feed I look and think "meh, that's a mildly interesting question" then I watch and come away mind blown. Every time.

[@someanonymousdude3609]

I actually agree.

"How Do Glaciers Move?" Like everyone else. They either hire movers or rent a truck and do it themselves.

[@alveolate]

you're losing your top ranked comment spots man.

[@Master_Therion]

Yeah, I have my good days and my bad days. But as long as I can give a few people a chuckle, I'm happy ^_^

[@feynstein1004]

Come on, people. Can we get some love for my homie Therion?

[@shellez207]

Noooo

[@Green-yf9py]

Boooo!!!

[@goatthrottler666]

I like this guy he teaches without being boring or condescending. You cant beat that.

[@thomster8639]

"Glaciers are cool.. not just because they are made of ice." nice on bud

[@rikkapikasnikka]

It was really cool that you got to take a trip all the way up north to Alaska! Great video, loved all those chill puns! Glaciers are fascinating in how they shape the earth around them and the incredible valleys, rivers, lakes, and everything else that is effected by their power.

[@yoMXTT]

You better have tried some glacier water.

[@besmart]

Best water I've ever had!

[@tea.lillith]

Fun Fact: In Germany there is a spirit called 'Gletscherwasser' which literally translates to glacier water.

[@bradleypeterson2208]

Fun Fact, the water they tried fell as snow over 200 years ago! The only other place you could get water nearly as clean would be a spring or another glacier.

[@-7070]

Yet another impeccable example of why the topic of understanding viscoelasticity can aid in understanding the planet no matter the scientific field studying it, and is always fascinating.

[@Dunkle0steus]

I heard that because ice is less dense than water (it expands when it freezes) enormous pressure can overcome this and can essentially "liquify" the surface atoms of ice into water. I've heard that as the explanation of ice skates, that you're actually sliding on a thin film of water, not the ice itself and that if it's cold enough, there won't be enough energy to force the water out of position and ice stops being slippery.

[@bongobongo3661]

It was ice to see a cool video like this one. Makes my heart slightly less frozen.

[@HopeSopeGaming]

I liked this very much. It helped me learn more about glaciers for homeschool.

[@nanic8394]

I'm glad to see this guy traveling and making videos like this. I'm just happy he looks happy👌

[@piplupcola]

So happy you collabed with my other fav scientist Sally!

[@terriblej6107]

How do they move? .... Slowly :)

[@vizthex]

No it's waterbenders

[@howiedavis8258]

About time SO get a segment lol I love it up here

[@JavierCR25]

This channel should be mandatory at schools everywhere. My son will watch at least 2 of your videos per day.

[@flavio-viana-gomide]

I found out recently this channel and have been watched many videos. This is really one of my favorite channels of all! 😄😄😄

[@sciblastofficial9833]

Every It's Okay To Be Smart episode but every time Joe says a pun "Another One" from the Sugar episode plays

[@OutlawMaxV]

Glad you get to travel to new places and learn new things, and share them with us!

[@Tomipolus]

I've been in helicopter once, got a 15 min free ride! :D Broke my right clavicle and left arm from hitting the wall on bycycle...so they had to transfer me from an island that had no hospital to the "nearby" city that had one. Cant say it was worth it...buuut...yeeeah...t'was nice.

[@deltaslayer1132]

"free"

[@NatureShy]

I’ve hiked by many, many glaciers in both Washington, Canada, and Oregon. I’ve even stepped 50 feet from the base of one in the Canadian Rockies. Outside of Alaska, Washington is the most glaciated state in the United States. If you want the best glacial experience in the lower 48, then you MUST hike or visit Mount Rainier National Park, North Cascades National Park, or Olympic National Park in Washington. In fact, practically all of Washington’s mountains north of Mount Rainier is heavily glaciated. Glacier National Park in Montana has got nothing on Washington’s glaciers! If you’re from Portland, like me, then you can hike on Mount Adams, Mount Hood, or Mount Rainier to see glaciers up close.

[@a.a.5880]

They way you enjoy science makes me enjoy watching your videos

[@Idk-lh2ot]

anyone else here cuz you disconected from your online geo lesson and then your mom was just like "just watch a yt video about it"

[@shr2.718ya]

This is the best channel on KZbin. I hate waiting for a new video every week

[@emanresplandor3878]

This channel is so underrated.

[@adamaewilson8392]

This guy was so excited about riding in a helicopter for the first time. Love the energy!

[@michaeldaugustine9249]

A good example of how a solid can move like a liquid is pure gold. Put a little pressure with your figures on a lump of gold and it will bend or stretch

[@Seamemaria]

uau I also want to be on top of that glacier. Glaciers ARE super cool. Was on top of one in Norway and it was just an overwhelming feeling. The intense blue of the ice is just incredible. Lets try and let the glaciers continuing being glaciers. Great video!

[@Ariminua]

Is it normal for a glacier to be so dirty? Like at 4:29. Is that just due to the erosion of the surrounding valley?

[@besmart]

Yeah, there's pretty constant winds up there bringing dust off the mountains and it piles up on the surface. You can only see it up close to the glacier though

[@dubya13207]

I can see that public TV budget at work...they couldn't even afford to give you a full-sized Snickers to squish!

[@Itznoelzz]

That's why I love your Chanel it's interesting

[@Grim_Beard]

DarkDiamond Snow21 Smells nice too.

[@SmartSula]

This video was so visually appealing

[@alexphelan6011]

You guys are great my parents say you guys are great cause I have fun listening and I learn a lot thx guys and keep it up!!

[@obezy.]

I watch you ,vsauce and the riddle like 24/7

[@SH1014]

There was one thing I didn't quite understand, does all of the ice on the glacier move or only the bottom part because oft that high pressure/low melting point combination?

[@Silmerano]

Has watched no less than a half dozen documentaries on Glaciers and knows exactly how they move. Watches video anyway.

[@gkys111]

Damn, an entire chapter of my college textbook condensed into a few minutes. a nice refresher

[@rickreynolds3604]

Great job, y'all--thanks! PBS is the best. :)

[@colbeyhair3149]

Thumbs up for the Bill Nye pun... "Glaciers are cool!" Well done.

[@Kraigon42]

I'm normally pretty slow to get at things (and I'm starting to like that), so I expect to miss a month-old three night special, but... Good job on advertising a three-night special two nights after it had already started.

[@h.grenukathilakarathne8356]

Welcome to the snow world, where snow evolves into firn then into glacier. Lol. Great Pokemon animation for snow to firn

[@katiecarroll1451]

I liked this video. Then you referenced pokemon using the original 8 bit music and now I love it.

[@neroquin]

Thanks for my geography test summary

[@parsasamandi569]

Great explanation!

[@filmackrakin9895]

00:51 When your fps of your camera matches the rpm of the heli's blades

[@besmart]

Or the engine hadn't started yet. But I like where your head is at!

[@filmackrakin9895]

Oh man..i saw the blade curved and i thought it was moving. Excuse me but i'm sleepy and its 2:32am in Greece

[@mrcoolabhishek123]

very well explained. thanks.

[@canadaiantenten]

You could have come to Glacier National park here in Montana to study glaciers, we've got lots! Or had lots..... they are kinda melting..... but we have lots of lakes made by glaciers and they are some of the clearest waters you will ever see

[@twofish.6579]

Thank you from an Aussie homeschool mum.

[@Moh-fu3gj]

You know why people like glaciers Because their COOL❄❄❄❄❄❄

[@manuelxd4231]

3:54 so COOL

[@michaelsilverbane11]

Got introduced to you from the Sally LePage Sofa Science vid. Subbed.

[@shimi594]

Thanks for the video!

[@pseudophd1073]

Beautiful scenery!

[@ozdergekko]

In the Alps, glaciers are receding at a speed that already has led to several once big glaciers completely vanishing.

[@matthewhardwell2780]

My mother asked if the table was okay when i fell onto it and hit my eye. 2 years later i am blind in that eye and thats a major contributing factor to the blindness

[@christopherbell5817]

A tortoise is mugged by three snails. When the police ask him to describe his attackers, he replies, 'i can't, it all happenend so fast'.

[@stebowo]

what's the name of the music that starts at 0:58?

[@1234bobfox]

I've been to that lake. They have a pretty neat building nearby with pictures and infographics about the glacier. I can't quite recall, but I think the people running that lodge also offer those helicopter rides

[@fijigoya1236]

I love how blue the ice was

[@gohanr1271]

the presenter was wearing SUN glasses in the SNOW i guess you could say he was to COOL .

[@tttylerpantsthesquirrel2814]

I was eating a very delicious brownie while watching this

[@ansambel3170]

Cool video, very refreshing!

Hey ice baby, your coolness lies in the way you move 😎😉

[@iceburnhex]

Love these videos... and the horrible horrible puns.

[@stevenbaumann8692]

You could have just said "ductile deformation". You talk about brittle deformation. Sometimes they will pick those boulders up. Also. You mentioned this but people may have missed it...even if a glacier is retreating the internal ice is still moving forward.

[@jimmyshrimbe9361]

Super cool!

[@x9x9x9x9x9]

This would have been the perfect time to go over why glacier ice is so blue.

[@TheJaseku]

fantastic work

[@a.g.7880]

Snow video in summer. Nice.

[@miles45ful]

The puns always kill me: "solids don't move... do they? NOT SO FAST"

[@miles45ful]

Also I cried when you used the old Pokémon evolution sound

[@Vidley1777]

When you cook water on top of a mountain, it boils at less than 100C, because of the pressure being lower than at sea level. So decreasing pressure causes a decreasing boiling point. Now my question is: How can an increasing pressure cause an decreasing melting point? Shouldn't actually the opposite be the case or did I get something wrong?

[@youlikewater]

don't think of it as a decreasing melting point but as an increasing freezing point.

[@SaraMiyamoto]

Basically, it boils (heh) down to the fact that water is weird. Water takes up more space as a solid than it does as a liquid. When you increase the pressure, you're effectively forcing the water to try and take up less space. When the solid ice can no longer be compressed anymore, the only avenue left for it to take up less space is to change states to a liquid, which allows it to be compressed more than it can be as a solid. The vast majority of materials we know of behave as you'd expect, in that higher pressures would make it take more heat to melt the material (heat is energy, and you're having to supply enough energy to overcome the increased pressure to reach a liquid state). Water, however, is just friggin' weird.

[@youlikewater]

Sakura Miyamoto it doesn't just apply to water. The Earth's crust acts must in the same way.

[@Vidley1777]

Sakura Miyamoto Thank you, now I get it :)

[@ethankim4086]

thanks. so helpful!!!

[@Pman8362]

Juneau is an awesome place

[@doof.1]

That Pokemon reference though. I just evolved both a Shiny Ivysaur and Oddish while watching this.

[@Rodman200818]

In my opinion, this is the best video of this channel! It was a delight.

[@TaT420X]

I went on the same helicopter to that glacier. I remember distances where hard to judge when standing on glacier.

[@jw8628]

This dude has a really cool job...

[@flurryv2987]

wow i was watching videos about glaciers when i got the notification.

[@lilyhuang3677]

AHHHHHHHHHHHHHHHHH the glacier puns guns? ok idk what I'm saying I'm trying to make a pun but unfortunately I'm too stupid

[@bengoodwin2141]

Before watching, I would guess it’s the same reason sand flows, but it’s melting and re freezing constantly on the inside

[@thelastcube.]

"Solid don't flow like liquids" Me : *cough* *cough* Amorphous solids *cough* Glass *cough* *cough*

[@besmart]

might want to watch Veritasium's video about whether glass actually flows 😏
