How to Make A Snowball Earth

- This is the rough draft of a tutorial describing " How to Make a Snowball Earth". It's pretty technical, but show much the Earth must cool to go from a "Super hothouse" typical of the late Precambrian to a full-blown Snowball Earth. One interesting discovery - The Earth probably had "dry ice" (frozen CO2) ice caps during Snow ball Earth. The removal of this important greenhouse gas certainly cooled the Earth further. - CRS Scotese 09/02/2022
Cool
Does the forward models indicate increase in global temp or going to cool down? Any impact of human activity on temp continue to stay higher and longer than models predict?
It was very interesting, thank you. I would like to ask how much time passes between stages? Where are we now? Can anything speed up the process?
Read some papers
@@alexanderconrad669 Oh, no, thanks. I'd rather look back at reality, it's safer.
Interesting! Thanks
Hello there, I have a question you may be able to answer. It is about continental drift. I know a good bit about plate movement but on up to this point nobody has ever answered the question : how do individual land masses break from one place and get to another place quite far away actually on a different plate. A good analogy is India. India started breaking away from Antartica during the early jurassic period and as you probably already know, Antartica has its own plate. A sizeable plate. Yet, India moved upwards moving over a destruction zone causing quite a bit of volcanic activity 65m years ago then collided with Asia creating uplift. How did India get from one plate to the next? Since these are obviously two large plates and are seperate. Does one plate consume another and landmasses are swapped or how does this work? I am trying to grasp with the idea and learn about it. Thank you.
that's actually a very good question. While I don't know the intricate details of indias tectonics it works like this:
the subduction and generation of oceanic crust happens at different rates across the globe.
So for example the subduction north of the indian plate and the spreading south of it happens at a faster rate than at other boundaries. So the plate must get translocated so to speak. Its not like its moving but the crust around it generates and subducts.
What do you think about a theory that the earth, surface area of this sphere, has actually expanded and contracted over time ….?
@@I.M.A.Panther3619 Indeed, I think so too. It expands and contracts like a heart. There is a break in between when neither.
@@penzeszsuzsannaliliom4270 I wonder about the atmosphere ….
If the earth does expand and contract, does the atmosphere become thinner or thicker along with the size of our sphere ?
That would have rather severe consequences.
@@I.M.A.Panther3619 Indeed. It won't get thinner or thicker, the transformation and movement in the atmosphere will just slow down. As a result, it is largely unsuitable for life on the surface of the earth, e.g. during the great ice ages.
Very nice. I'll make a snowball earth tomorrow. I simply need to know what microorganisms are necessary to start it, so I have to experiment a little.
Hey this a collapsed is a Ussr and yugoslavia and south sudan and Eritrea exits this change map!
Pls back you
CR Scitese,please upload a ew video
I think he’s dead or not he’s 64-73
Sooo if life on Earth keeps the planet in homeostasis we probably should protect biodiversity. 😅
But could the earth actually be flat?
@@ashleycarone894it can sphere it can be flat (I personally believe it’s sphere but it’s your choice on how to see everything 😃
@@rhyolite Flat in 2 dimensions, spherical in 3 dimensions.
It depends on where our consciousness looks at it. Life is only in 3D.
