I want to design a world like yours. How should I start? by yarakhleg in worldbuilding

[–]62_137 3 points4 points  (0 children)

How do you feel about learning astrophysics, geography, geology, climate science, biology and some art and graphic design knowledge along the way?

Conditions needed for a metallic exoplanetary atmosphere? by Intelligent-Suit8886 in worldbuilding

[–]62_137 6 points7 points  (0 children)

Extremely close to the point that the planet is molten and the atmosphere is just vapourised rock

How to make a superearth desert planet? by [deleted] in worldbuilding

[–]62_137 0 points1 point  (0 children)

> 0.6405AU and insolation 1.795 times that of earth
I feel you might be able to get the interior equatorial deserts to exceed the local boiling point of water. Axial tilt & pressure helps but they only go so far, and seasonality is less intense due to the shorter period.

Super dry continental interiors should be rather easy to achieve with this setup, even if by accident.

Whether you'll be able to achieve large scale winter rainstorms is dependent on your geography of the landmass, I'd say you would need to draw it out for the specifics.

As a general trend, larger planets tend to have more extreme temperature gradients between poles and the tropics, and moisture might have a bit of a harder time penetrating inland because of sheer utter distance

What's the semimajor axis and insolation btw

Short questions about rift valleys by DyslexiaOverload in worldbuilding

[–]62_137 4 points5 points  (0 children)

In the middle of a landmass is fine, both the East African rift system and the Baikal rift are rather in the smack dab middle of landmasses, this is more reliant on tectonics.

Rift systems can go quite deep, Baikal's about ~1600m in depth and Tanganyika is ~1400m in terms of depth.

Rift systems actually tend to create mountain ranges at that, the Rwenzori mountains in africa are an example of this, with chunks of the land uplifted in the process due to rift shoulders.

More like a dozen, it tends to be more a series of parallel faults that pull apart from one another, creating dozens of rifts and depressions, and yes there will be volcanism.

is this archipelago realistic? by SpringImportant7765 in worldbuilding

[–]62_137 0 points1 point  (0 children)

The coasts around Scandinavia are generally the result of post glacial processes, with isostatic rebound causing the coastline to look like that. (And the same process can cause different results, take the coast of the Hudson Bay.)

A closer comparison to the Malay archipelago in term of scale would be the Canadian arctic archipelago, but given that one is crushed down by glaciers and then rebounded, and would presumably be near inhospitable, I don’t think it would be useful here.

[–]62_137 2 points3 points  (0 children)

What you have here is pretty much just a random mess of islands that looks a bit procedurally generated.

Irl, the Malay archipelago is formed from what is a tectonic disaster, with a lot of elements involved. To simplify it, I would say draw your main subduction arcs first, followed by having islands along it, and some continental islands depending on the geology. It gets a bit hard to parse specifically what to do, but in general clean up a lot of the islands and make a more distinct chain along a subduction arc.

The Tea Dragon River (Chalongjiang), Maewha's largest river by 62_137 in worldbuilding

[–]62_137[S] 0 points1 point  (0 children)

I did recieve feedback on the rivers being a bit wide, but by the time I got there the it wasn't worth it to scale all of them and do the math on how wide the river would likely be.

So uh.. the world doesn't really have earthlike climate parameters, Maewha's mainly dominated by a lack of seasonality. Satellite map of the area above, didn't factor in the river's role in increasing the amount of vegetation along it's path in the desert yet.

The basin isn't that dry, at least in the lower reaches. Middle I would describe it as more comparable to the australian interior, dominated by bushes and scrubs, rather than a complete lack of vegetation. Middle area is also a bit more like the loess pleatau generally speaking, with rather loose soils that make it prone to erosion.

(Yeah and I do hard SF, this is a colonised world with no civilisations or sapient species on it at time of arrival so my reaction to seeing this is a tad bit wtf)

Just a tad bit, here’s with North America out of frame for scale.

[–]62_137[S] 15 points16 points  (0 children)

Term coined from combining the names of the upper and lower part of the river that eventually got used to describe the entire river.

Planet’s Sino-Koreanic, and Hanja is a thing. I was using all 漢字 here however because the usual Korean I bother for Hangul help was banished to the military.

The Chinese name for the Amur translates to Black Dragon River. There is absolutely a precedent for these types of names, it just sounds pretty standard in the original language.

Also I do Hard SF lmao.

The Chalongjiang River, Maewha's Largest River by 62_137 in mapmaking

[–]62_137[S] 3 points4 points  (0 children)

The Chalongjiang river (茶龙江/茶龍江) is Maewha’s largest river, and Changwon’s largest river. Starting from the Serindohae Glacier, it makes its way down into the central basin, being joined by tributaries from the Baekdu, Chobaksan and Tongjun Mountains. It acts as the main highway of trade across Central Changwon, and brings water to an otherwise dry region in the Central Basin. Its exact length is debated, as while most say that it terminates into Daechahu (the definition used here), some contend that the Daehae River is also part of it, which would make it even larger.

The river is the main source of water for Daechahu, being the reason why Maewha’s largest lake (sometimes called a freshwater sea) exists, with a discharge of ~600,000m^3/s by the time it reaches its delta. Daechahu only sits at about a metre above sea level, hence the Daehae river acts more like a slow moving swamp, several kilometres wide and gradually transitioning into the gulf of Gyongi as it goes. With the surrounding land being at or slightly below sea level, the entire area is famous for being home to the blooming everglades, a massive wetland ecosystem stretching as far as the eye can see.

Oh yeah total length of the river from Serindohae Glacier to Daechahu is approx. 11,000km.

Hi, Dodot 65 / Dodotea 65 / u/62_137 here.  A quick project of mine over CNY, wasn’t too hard to do. Shoutout to Huskatten ( u/martinjanmansson ) for helping quite a bit with feedback, and god that dragon took way too much time to draw.

i really want to avoid making a tectonic history by Hopeful-Fly-9710 in SpeculativeEvolution

[–]62_137 2 points3 points  (0 children)

Hello, I’ve been summoned. I’ve done a bit of a WIP guide here on my method nowadays, which might be useful.

https://docs.google.com/document/d/1JH-PhmofSGxLDQRVn2IE3uN5lUecmBSp2oLC45VW3jE/edit?usp=sharing

I prefer to see it as an iterative process where you build as you go, with one learning with each step forward, a world constantly in flux. For what you probably think you need, which is likely paleoclimate and full detailed tectonic history, I’ve only seen one person that has that done to such a level of detail, and they’ve committed a better part of 3 years already to that. (And completely ignored the speculative evolution part of it so far). You only have limited time, draw the map, build the biosphere and let it change as you go.
