How Do Glaciers Move? TIMELAPSE! | Earth Science

A timelapse allows us to see glaciers move and understand how their movement works.

Secret Life of Ice
Ice is one of the strangest, most beguiling and mesmerising substances in the world. Full of contradictions, it is transparent yet it can glow with colour, it is powerful enough to shatter rock but it can melt in the blink of an eye. It takes many shapes, from the fleeting beauty of a snowflake to the multi-million tonne vastness of a glacier and the eeriness of the ice fountains of far-flung moons. Science writer Dr Gabrielle Walker has been obsessed with ice ever since she first set foot on Arctic sea ice. In this programme she searches out some of the secrets hidden deep within the ice crystal to try to discover how something so ephemeral has the power to sculpt landscapes, to preserve our past and inform our future.

Welcome to BBC Earth Science! Here we answer all your curious questions about science in the world around you (and further afield too). If there’s a question you have that we haven’t yet answered let us know in the comments on any of our videos and it could be answered by one of our Earth Science experts.

Hell no!! I'd feel like I was descending into my grave. Brave woman!

[fahimsiddique]

Curiosity has driven her to the state of fearlessness.
Amazingly beautiful work!

[sreenjaysen]

This is probably one of the most insane tasks done on TV.

[heenanaz]

Okay I'm suffocating just by seeing her descending down through the crevices.

[spamslurper]

Anyone else seen videos of people stuck in those and she just goes straight in with a huge smile on her face?!

[jasontears]

All the questions I had about my newfound, middle of the night and procrastination-inspired fascination with glaciers have now been answered. Great vid and shout out to r/TIL for sparking my caffeine-infused interest and letting me avoid studying a little longer

You can watch ice movements in ditches after a heavy snow then a slight warming. The packed snow turns more into ice as it slides down the sides. Then as it slides down the slanted property into the neighbors property it shrinks as it melts, refreezes, and serves as a slide for kids.

This was so fascinating. The time lapse brought me to awe.

[massatube]

She's a braver man than me. I wouldn't go down on a glacier. lol

[gunturjeans]

Look at what the captions say at 1:03 😂

[tsuchan]

Nice. That's the most interesting Earth Lab video I've seen so far.

[terrylap]

If I went into that crevice, I would’ve developed instant claustrophobia.

2:33 *I thought there was a corpse in the corner, scared the hell out of me*

[YourGirlPratiksha]

FUN FACT : 2:30 i see a face in that rock😵😵😵 anyone else?

[donaldthompson]

[LocalRando_]

Who's here because of online school?

[sandmanjono]

Fascinating- Mother Nature as ever truly awesome!

[fredMplanenut]

It is amazing to be under a glacier and hear the creaking noises. Also, fascinating is the blue of the ice with the light refracting through it.

[JWCreations]

Surprised to see her abseiling without a helmet!

[quaidcarlobulloch]

She seemed so stoked to be there. Really cool to see.
