| How long would it take for the continents to move and create some crazy land masses like Pangea? Posted: 06 Mar 2020 07:16 PM PST How long would it take for the continents to move around and make a new giant landmass or be in much different locations like 10000 mile difference?

| Posted: 06 Mar 2020 07:00 PM PST From what I've read, the main difference between sand/silt/clay is the particle size, as well as the shape of the particles to some degree. But I haven't found any resources that effectively explain what sand vs. silt vs. clay actually are. Sand is ground up stone, which are primarily silica (SO2), right? So is silt roughly the same composition but smaller? Or is silt and clay only made by organic matter decomposing? If anyone has some good reading resources on the subject, I'd love to go through them. [link] [comments]  |
| In humans who are tetrachromats, what is the wavelength of the additional color they’re seeing? Posted: 06 Mar 2020 01:08 PM PST My understanding the supposed "extra color" is a mix of red and green light, but do we know what that shade is? Additionally, do we have any idea how common it is in nature? Apologies if I'm approaching this question the wrong way- I just learned about this phenomenon today. [link] [comments]  |
| What happens when a plane is struck by lightning? Posted: 06 Mar 2020 08:42 AM PST There's this video going around reddit of a plane getting struck in the wing and it barely seems to shake. Is this normal or do planes usually take damage from these strikes? What do planes have to help protect them from lighting? How often do they tend to get hit? [link] [comments]  |

| Does NASA actually see these huge asteroids that are posted on social media or is it for clicks? Posted: 06 Mar 2020 09:17 PM PST i know NASA does see asteroids, but are they all as "Earth ending" as these social media articles or is it for clicks? i used to be terrified of these things when i was younger now i wonder if NASA does see these earth ending asteroid everyday.

| What makes a substance "sticky" ? Posted: 06 Mar 2020 05:56 AM PST And why do some substances seem to bond/stick more easily to some substances than others? [link] [comments]  |
| How do nerves work in transplants? Posted: 06 Mar 2020 10:02 AM PST I was always taught growing up that damaged nerves couldn't be regrown or repaired under any circumstances. But I just read an article about transplanting hands which seems to go against what I learned. How can they connect the nervous tissue between old arm and new hand? Especially in patients that lost hands decades ago? Can doctors in fact regrow nerves now? What does this mean for spinal injuries and the infamous "head transplant" surgeon? [link] [comments]  |
| How do butterflies "decide" which plant to use as their host plant? Posted: 06 Mar 2020 08:18 AM PST Is this a preference that is learned over many generations or is this something completely innate/intrinsic and that defies explanation? [link] [comments]  |
| Do any birds engage in surplus killing? Posted: 06 Mar 2020 09:27 AM PST |
| How how are some viral deseases seasonally? Posted: 06 Mar 2020 05:28 AM PST I read people get cold in winter more often because the immune system may be down due to the lack of sun. Is that the only reason? Is there any relation between temperature/UV light and the prevalence of viruses? I mean, does winter have an influence on the virus or on the human body in order to be more contagious on cold weather? Thanks everyone? [link] [comments]  |
