    There is a lot of idiocy in science. Derp aquifers, etc. Etc. Are generated by rainfall which creates erosion. Science done by idiots is unnecessarily complicated and a stupid waste. The real science is proving this generates tectonic uplift, rather than a static hold because of solid rock structures.

    I'm wondering also if added rainfall contributes to higher quantities of biomass that then become layers of soil compacted over time. For instance would mountains in a rainforest grow taller and larger faster than same mountains in a desert climate with similar tectonic activity.

    How about a simple correlation study of age of mountains vs height. My hypothesis is old mountains are low, young mountains are higher. Plot, correlate, Ta Da!! Young, high mountains erode to low, old mountains then throw in rainfall vs height and rock hardness vs height correlations. Draw conclusions. My is rainfall does not make mountains higher.

    One time in my high school ancient history class, we were talking about Hannibal's crossing of the Alps with a huge army and war elephants during the Second Punic War. My friend didn't understand why this was such a big deal and he asked the teacher, "wouldn't the Alps have been a lot smaller back then?" She asked what he meant, and his attempt to explain made it clear that he thought mountains were like plants, and that they start out as little hills, and then grow over time from being exposed to sunlight and rain. We've been roasting him over this for years. But now I guess in a way he wasn't entirely wrong.

      @Mischa Rowe Eh, no a computer model does nothing to remove bias, why would you even think that? Take the life on mars example; they detected a biomarker on Mars, couldn't think of an alternative hypothesis for its pressence and proclaimed "Because we can't think of any other possible explanation it **must** be life!" Here we have a computer model that even in scishow's video they TELL you "Tested to see if rain would match the results" aka not even considering alternative hypothesizes It sounds like you didn't even think about what they told you in the video

      @Dr Gutowski Unaccounted variables, like what? You do realise that testing on a hypothesis isn't done to *confirm,* right? The whole point of the scientific process when testing one's idea is to try to debunk it. While nothing is perfect, this process is literally designed to remove bias. Sounds like you're arguing that science shouldn't be examined because *you* can't imagine how to remove bias from a test.

Are you **sure** you accounted for them all? This is the same trap that led people to believe the "life on mars!" claim

    But even through rivers, the material does not move from the mountain to the ocean floor overnight: Most of the material remain on the bed (If not the banks) of the river for thousands of years and even if it makes it to the mouth of the river and to the sea/ocean, most tectonic plates stretch out for kilometers into the sea, so if it drops there it is still on the same plate and contributing the same weight to that plate; not to mention that all that is only for rivers that make it to the sea (Taking the Canadian Rockies as an example: Only a few rivers on the western side of the rockies make it to the ocean, many fall inwards to lakes between the mountain and many others fall eastward toward the praries, so all that material indefinitly satys on the same tectonic plate!). The insignificant amount, even over the milleniums, can't make THAT much of a difference (Plus, given that it is widely accepted that much of what is now part of the western mountainous edge of Canada use to be a series of Islands on the Pacific plate, those land masses probably compasate for what was lost and creates a barrier for "river material" to reach the ocean; this would not apply everywhere, of course, but other processes elsewhere are probably often present). The overall picture of the presentation seems to be quite lacking in scope!

      It's because of the way the tectonic plates move against each other. There is little subduction of one plate under the other which causes the plate to melt and form lava producing volcanoes. Instead they just crash into each other.

    1. James Cooper
      James Cooper
      Muaj më parë

      @Valerie Pallaoro Although carbon is in a gaseous state, it was solid and in the the ground, mostly. The weight of the carbon in the air has to be adding pressure to the earth, I'm guessing, just as the weight of water adds atmospheres as you sink in the ocean. I am wondering if the weight of the carbon in the air is having an effect on the physical structure of the Earth.

    2. Valerie Pallaoro
      Valerie Pallaoro
      Muaj më parë

      What are you looking for? Carbon in the atmosphere is attached to oxygen molecules and is gaseous. So are you talking about the weight of the world to the Karman line or to the troposphere because three quarters of the atmosphere's mass is there and it's probably easiest to measure. And does this mean you think the weight of the world is measured to the edge of outer-space ... *sigh*

      @Guy Montag Yeah, they acknowledge reality and science more than most people think. For example, it's a myth that Creationists don't believe in any kind of evolution. They fully accept micro-evolution, or adaptation and change within a species (like Darwin's famous finches). It's macro-evolution that they have an issue with, this being one species changing into a completely different one (apes into humans, dinosaurs into birds, that sort of thing).

      @Zachariah Dearing I had no idea creationists even allowed such things as starlight to factor in. I assumed they just ignored all the inconvenient science. I don't honestly know if I think it's better or worse that they're actually acknowledging reality to some extent and yet still sticking with their creation myth. I'm leaning toward worse.

      @Zutto Aragi Yeah, no. As someone who grew up homeschooled in a Creationist household, I can say that that is only partially true at best. Firstly, the Bible _does_ _not_ say that the mountains rose after the Flood. What it does say in Genesis, Chapter 7, is that the Flood covered the mountains to a depth of fifteen cubits (or a bit under seven meters). It also says, in the following chapter, that the "fountains of the deep" had opened. Now, do some Creationists claim that the mountains used to be shorter? Yes, but they attribute that to tectonic activity, just like everyone else. To be clear, I don't 100% agree with everything I was taught as a kid anymore. The Creationist answer to how starlight could be here if the Earth is less than 10,000 years old never made much sense to me, for example. But I also won't ignore obvious misunderstandings (or worse, lies) about that line of thinking.

    I thought he was going to discuss how hydration of minerals in mountains would increase their size. I’m not sure if that is something that happens, since I don’t know much about those kinds of processes, but it seemed like a good hypothesis to me.

      @ckl That would change things as well. As would any form of carbonate formation which requires rain to pull CO2 from the atmosphere.

      On a similar note, what about mountains that contain large quantities of un-oxidised, or partially oxidised, minerals that upon exposure to air or water react and add that mass to the mountain? I remember hearing (but not from where) that one of the first CO2 droughts in prehistory was because of the Himalayas emerging from the crust. Apparently they contained lots of CaO that had never seen air before and promptly absorbed the CO2 to make large quantities of CaCO3. It's been a long time since my last chemistry refresher, but CaCO3 would be significantly heavier than CaO.

      @Valerie Pallaoro valid. I was only thinking of actual expansion of the volume wise, but if we are talking porosity... A porous mountain that is full of water (an aquifer) is much heavier than one that has had the aquifer drained. So yeah, porous without water weighs less than with water.

      (along with all the other good points) it would also depend on your mountain. Some sedimentary rocks absorb more water than others, some stay held together and others are washed away. I think though; at the highest point, a mountain is of less absorptive rock; the most absorption of water would take place lower down.

    I'm having a hard time understanding the dating technique described here. Does more beryllium 10 mean faster erosion or slower?

    1. 하람배
      하람배
      Muaj më parë

      they said beryllium 10 doesn't form much below the surface, and the researchers took samples of eroded rock to make the measurements. after the rocks are "eroded out", new rock is exposed in the mountain, and the rock pieces are left to accumulate that beryllium variety, so the more they have the longer they've been left out (if there's new rock eroded it'll have less of the beryllium 10, because it sat there for less time). does that make sense?

      Does have a bearing on how much is eroded away though; they can rise due to isostatic rebound and plate tectonic collision, but if they are being eroded at the same rate as they rise then it's a steady state, if they are eroded more than they rise, they get smaller

      @Wemple Same thing with gorillas and billi apes. They were considered cryptids for years, in the billi apes case over 100 years of people not believing locals and their experiences until 2003 when a specimen was found. That being said, I saw ape-like creatures in san diego about 3 years ago. I am absolutely sure that we have a local ape that people haven't researched.

    If the purpose of life is to reproduce why does reproduction get hard as life advances compare the strain of mammal pregnancy to sponges that be cut up. Claim just spray in the water. And where's the selection there . I under how . but why? Unless there more to life being alive. Viruses do nothing but reproduce. When think of being alive. Its processing energy being animates scientifically much closer to metabolism.
