There is one video in the internet that much explains all kinds of snowflakes and how to reproduce them. I cannot remember which channel, though, for which I'm sorry. That guy studied snowflakes for like 20 years. Of what I remember, hexagonal nucleation was the basis, and then temperature and degree of humidity could be adjusted and changed to promote the growing of any type of snowflakes desired accurately.

Here in NM we call sleet a rain and snow mixture. It’s common weather here in the high desert this time of year

As a big meteo-nerd that's been through many rounds of NWS spotter training, I think the golf-ball-sized hail quote you mention is for reports of _damaging_ hail specifically. The usual minimum size considered severe is ¾" - about US nickel sized; the vast majority of hail falls below this. It's impressive to see, but causes almost no damage until you get above that. Even up to 1½" will mostly cause only minor dings and damage. It's only when you get to golf ball sized (1¾") that things really start to smush and smash, which is obviously going to start garnering many more reports of damage.

My understanding of needle and "hoarfrost" is that it has to do with plants' transpiration, the crystals start by water evaporating from the plant and that's how the formation starts but I could be wrong. Also: I saw graupel for the first time two years ago. It happened while I was looking out a window, it looked like bean bag filling and it seemed to all appear at once, like it just formed in the air and dropped and was over.

This was great. Did not know there was that many types of snowflakes, growing up in Northern BC we just classified it into "lots" or "tons". I was waiting to learn more about ice-nine that I first read about in Cat's Cradle.

One of my favorite books I discovered on my father's bookshelves was Isaac Asimov's "Extraterrestrial Civilizations." It's the original "Rare Earth Hypothesis" book. Even the authors of "Rare Earth" didn't know about it(i finally showed them Isaac's book after a few tries spread over a few years.) Well, Isaac show how so many factors come into play that would prevent multi-cellular life(not single cell life) from happening. Looks like you found another factor that would probably limit life. In fact, this heavy ice problem probably limits single cell formation!

Rachel, I think another ice related topic would be a discussion of permafrost. As the earth continues its current warming trend, permafrost microbial activity increases resulting in the out gassing of greenhouse gases like methane and carbon dioxide. Having done so much field work on the North Slope I became fascinated by permafrost, it’s origins and it’s unique structures. Another fascinating side topic is the abundance of Ice Age mammals preserved in its layers. In my wanderings I stumbled upon many fossils from that time period. I remember reading that more fossil mammoth ivory has come out of the Siberian tundra than modern ivory from Africa and India. As always, Rachel, a wonderful summary on ice. Many thanks!

After nucleation of an ice crystal on a surface, the needle-like frost could grow by water vapor attaching itself to the already frozen root of the crystal (being that it’s the coldest thing in proximity), rather than condensing on the branch and then freezing, which would look more like an ice sickle and not the needle structure of hoar frost.

I've never heard of GEO GIRL but I'm impressed. You've earned a subscriber. The discussion of ice moons, and the implications of different ice forms on the likelihood of life, is fascinating. However, it would appear that if these worlds have kilometers of icy crust overlaying a global ocean, that ice cannot be denser that the ocean beneath. Perhaps the liquid water is more of a thick brine, which has its own implications for life.

I asked ChatGPT why ice forms in needle-like structures around tree branches, and one idea it gave me is that tree branches are bumpy so they have a lot of nucleation sites for ice to form. This is probably not a complete answer, but perhaps a partial one.

Hoarfrost can create dramatic and stunning scenes as ice needles form on objects in the wintertime

Water below its freezing point is highest density and need to remain still? I think yes, and any motion activity starts nucleation I think yes. Is ice from a iceberg different densities from top to bottom? Does air migrate out of ice to make its density increase? I don't answers but as much as covered I still formulated a few questions.

@GEOGIRL

Жыл бұрын

Hmm, I don't know the answer to all of these, but I can say that icebergs are likely the same density throughout because they are made up of a single ice crystal structure (ice Ih), and because the crystal structure determines density it remains the same throughout the entire iceberg. All naturall occuring ice on Earth is dominated by ice Ih (only very trace amounts of cubic ice and ice VII exist in special scenarios). So in general all ice on Earth is the same density. It is only in the lab or on other planets/moons where denser ice can form because we can subject it to much higher pressures than those naturally found on Earth in the temperature range at which water ice can exist. I hope that answers at least some of your queries ;)

Their is one form of ice in air, and that is called "Ice Fog" which is a type of micro ice formation suspended and FLOATING in the air that looks a lot like fog, but isn't, it also feels different than normal fog to breath.

I had heard about these extraterrestrial water ice forms. Obviously I knew Ice is less dense than liquid water, which is good for the fish, thanks Geo Girl for explaining the bonding that enables this, and structural forms of space ice! Though the ice I am more interested is ice cream, sorbets, gelato. There are at least 19 types of ice cream at the ice cream parlour, like tutti frutti, choc chip. It is amazing though there’s ice that would sink in water, that’s really strange, an Alien Titanic would be OK. I’ve heard that The needle like structures are caused by someone called Jack Frost who does it by some sort of magic. I presume Ice forming around carbon particles from jet exhaust is what causes vapour trails? Also, the hail stones going up and down would that generate static charge? And are ice meteorites a thing? Or is it just ice falling from planes or super giant hail stones? On snow I recall once large hexagonal flakes falling on me and not melting and I could see them getting mechanically entangled with each other

Mentioning the Tunguska event and the theory behind it, that it might have been caused by an ice meteorite/part of a comet - would probably have blown the scope the video - but thanks anyway, I didn't know that that many forms of ice can possibly exist.

One more interesting type of ice formation is hair ice which forms around dead wood colonized by the fungus Exidiopsis effusa. The exact mechanism isn't fully understood but its only in the presence of this species of fungus that hair ice forms and it likely has something to do with the fungus's antifreeze molecules inhibiting ice nucleation thus constraining the behavior which ice can exhibit when it crystalizes. As for impacts of high density ices one of the big recent discoveries in astrobiology/abiogenesis research is that basaltic glass a.k.a. amorphous solid basalt catalyzes RNA formation. This catalytic effect appears to be due to the more mafic nickel which is why obsidian a.k.a. rhyolite glass doesn't have the same effect. The significance of this is that if you lack a means to put amorphous basalt into contact with water it would be problematic to get RNA one of the essential molecules for life as we know it. But since we are talking about how weird water is as a substance it turns out water even has at least two distinct liquid phases. There is water as we know it characterized by its hydrogen bonds but there is also apparently another kind of water with a different style of hydrogen bond interactions at least sort of. Its technically quite a bit more complicated than that as these pure phases of water which correspond to the organization and behavior of hydrogen bonds don't like to exist separately instead they normally exist in a dynamic quantum superposition of states not really fully one phase or the other which some work suggests is the cause for water's bizarre mix of properties as a liquid. www.pnas.org/doi/10.1073/pnas.1705303114 physicstoday.scitation.org/do/10.1063/pt.6.1.20201119a/full/ A big implication for this is that water is fundamentally irreducibly a quantum object and as the relative weightings for these two states vary with temperature and pressure it means the chemical properties of water itself vary with temperature and pressure which has long been known but has remained hard to explain. It was originally hypothesized that there might be several phases of water because we have known that two different amorphous phases of water ice exist HDA ice and LDA ice which is unusual for a given liquid as normally a liquid phase corresponds to its amorphous phase. Given that you brought up a third Very High Density Amorphous Ice then I would not be surprised to learn that a third liquid phase exists with a far lower probability amplitude/weighting since it took many years to not only show that it might be possible to isolate these phases under supercooled conditions but to actually succeed in experimentally isolating them. If this is the case then there may be more hydrogen bond interaction phases out there to discover. Quantum superpositions are a bit hard to understand so this is a bit of a tricky subject to discuss without the relevant background in quantum mechanics.

@6:20 ish. Wouldn't hot vents (the best candidate for abiogenesis) still create non-frozen environments for everything to occur? Also, many areas of the ocean have an ice free ocean column. I've heard it said about sinking ice stopping abiogensis/evolution, but how would that work exactly? Pressure so high it still freezes?

@GEOGIRL

Жыл бұрын

You are absolutely right that hot vents would prevent local freezing, but we don't know if these vents are temporally stabile (whether they are intermittently or permanently active). If the vents spatially and temporally vary, then they may not be stable long enough in one region to allow water-rock interactions to produce enough chemicals to produce enough energy for life to evolve (or allow enough time for life to evolve)... And we know so little about the origin of life to begin with (the environment or amount of time it requires) that we cannot even say what these requirements would be haha Anyway, based on what I've read, it seems like we are pretty sure Enceladus's and Europa's ocean floors are likely not covered in dense ice, or the layer is thin and spatially variable enough to allow plenty of active hot vents to remain stable for long periods and thus, allow a potential origin of life. Whereas, Ganymede and Callisto may have dense ice layers so thick that it prevents any vent activity which could fully prevent life. This comment may bring up more questions than it answers haha, but I hope it was at least fun to read lol ;)

@GEOGIRL

Жыл бұрын

Yep, all of the ice you are familiar with on Earth is hexagonal at the molecular scale. Snowflakes that are hexagonal in crystal habit (macro-structure) are formed under conditions at which their internal molecular structure dictates their macro-structure, but in most crystals, their macro-structure (or crystal habit/form) does not have to 'match' their molecular structure. For example, calcite has one molecular crystal structure (hexagonal), but has many different crystal habits at the macro-scale: it forms prisms, cubes, dendrites, stalagtites, nodules, needles, etc. So in other words, the micro-scale structure ditates the macro-scale structure but can result in a wide range of macro-structures because the hexagonal molecules can be arranged in all sorts of different ways. Hope that makes sense ;)

Ice forming on branches can be a result of sleeting (frozen rain - not hail or snow)

@GEOGIRL

Жыл бұрын

I have an answer: Rocks! Well there is a much more complicated and detailed answer, but the gist is that we can look at how rocks have been deformed and oriented in ways that we know they weren't originally deposited. Then we can deconvolute their history of movement and from there we can look at the direction of stress they were placed under and when they were placed under that stress (in other words: when the mountain formed and what direction the tectonic forces were moving to uplift the rocks that formed the mountain). From this information we can determine whether there was a plate boundary at or near that place at the time the mountain formed and what direction that plate was moving to form those mountains. Now there are times when the mountains formed without the need for plate tectonics, this typically means they formed due to a hot spot (a hot rising part of the mantle that formed volcanos at the surface, like Hawaii). However, when mountains (or volcanos) are formed from hot spots instead of plate tectonics, the rocks end up with a distinct composition, so their chemistry as well as their physical appearance can tell us a lot, but it is hard to put into words with no pictures, so I will try ot make a future video to explain it better, ok? :)

No damn cat, and no damn cradle.

So if aliens visited us our snow and ice would be utterly alien to them? (serious question) I had no idea this was the case.

That makes me feel better about the way I'm writing the aliens in my story lol
