How Do Glaciers Move?

This video is so cool, it's ICE COLD

Glacier ice is weird. It’s solid. Solid things aren’t supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

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

"Solids don't flow right?
Not so fast"

Why is no one appreciating how perfect that was!

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.

Well, I'm gla-sure you did your research on this one! Neat topic, keep up the great work.

[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?'

Snow: This isn't even my final form!

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

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.

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.

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.

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

Don't let this distract you from the fact that if you or a loved one has been diagnosed with mesothelioma, you may be entitled to financial compensation

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

[piplupcola]

So happy you collabed with my other fav scientist Sally!

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.

You better have tried some glacier water.

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

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