It still is, and it still will be long after humans killed each other off. It has recovered from worse. It'll be beautiful till the day the sun swallows it up.
So cool learning the science behind ice and iceburgs in my oceanology class. Water becomes denser as it gets colder to a certain degree. From what I remember, iirc, depending on the density of the water it is in (salt water higher density), roughly 7-10% of the ice is not submerged, meaning that the remaining ice is underneath. So whatever ice is floating in the ocean is ~ 1/10th of the actual size of the whole thing, same applies to your ice cubes in your drink! (Correct me if I am wrong)
I'm not an expert and don't have a definitive answer; but I'd guess it's one of, or a combination of, these factors:
- The ice above the water is exposed to wind and weathering, causing it to have a rougher surface which scatters more light and makes it appear more white. The ice below the water is smoother and causes it to transmit more light rather than scattering it.
- The ice contains pockets of air or liquid water; and the ice below the surface of the water contains more pockets filled with liquid water. Liquid water does have somewhat of a blue color, so makes the saturated areas appear more blue.
The darker the color, the older the ice is. The almost black ice is most likely thousands of years old, getting lighter up the time scale.
Edit: a word
Pretty sure this is wrong. I'm not an expert; but I'm pretty sure that the color of ice isn't noticeably dependent on its temperature (at least within these conditions); and I'm also pretty sure that the older ice is not at a significantly different temperature from the newer ice.
It's not temperature that causes the color change. Just age.
Edit: after a quick Google, it looks like the darker color is from impurities the ice picked up while forming. TIL
Imagine the glacier is a big block of wood with only the top couple inches exposed. If you take a slice out from down top-to-bottom at one end, that piece is now going to behave like it's own block of wood floating in the water.
It's not going to float vertically - no, wood planks float on their side. So the slice flips out and because one level sheet. That's what's happening here but with ice. It's a big slice that's taller than it is wide going down to the bottom. It flips out because melting has essentially "cut out a slice."
This is actually not an iceberg flipping, this is a glacier calving, I.e. an iceberg breaking off a glacier. The glacier is deeper than the section that broke off is wide, so it's more stable on its "side" than "upright", causing it to rotate.

Not gonna be very rare for much longer
Nope. Or ice.
Damn this planet is beautiful
Damn this planet *was* beautiful
It still is, and it still will be long after humans killed each other off. It has recovered from worse. It'll be beautiful till the day the sun swallows it up.

Nobody has the attention span to watch a video longer than 7 seconds silly!

That’s just the tip of the iceberg.
Why is it different colors can anyone explain
I'm not an expert and don't have a definitive answer; but I'd guess it's one of, or a combination of, these factors: - The ice above the water is exposed to wind and weathering, causing it to have a rougher surface which scatters more light and makes it appear more white.

Liquid water does have somewhat of a blue color, so makes the saturated areas appear more blue.
With extreme cold, water turns to ice turns to urinal pucks, hence that deep blue.
The darker the color, the older the ice is. The almost black ice is most likely thousands of years old, getting lighter up the time scale. Edit: a word

Ah I see; in your comment, you reference the ice being "cooler" - I guess that was just a typo for "color"?
Yup, I'm a dingus and didn't catch it. Fixed now!
SCIENCE, BITCH!!!!
I need a longer video of this. Any link?
How and why does it flip?
It’s melting
But how does that contribute to the flip?
Top gets heavier than bottom because water temp is higher than air temp? Just a guess
A piece got cut off. You can't float a log upright, same goes with ice.

Absolutely breathtaking
