I am trying to think of a natural event that causes very big impact to human lives - massive movements of people, shift of power, etc. This event happens in a medieval period on an earth-like planet. ...

I'm building a world which has, apart from the 'usual' stuff, 2 types of stones (haven't really decided on a name yet). Stone A holds some form of energy but when prompted by Stone B it will release ...

If a planet has a core of super-dense material, how might that effect the geological composition of that planet? Specifically: imagine a lunar-sized planet, with earth-like geology and density. If ...

I'm imagining an Earth-like world with a single large continent centered on the north pole, and not reaching entirely to the equator. As ocean currents play a large role in shaping weather, I'm ...

In my world, there would be a tropical region very similar to real life rain forests, though underground there's still jungle. At a point underground, there are huge caverns that are populated by ...

While constructing a planet, with the same mass, volume and overall composition as Earth, how do I know how many tectonic plates should it have? And what does having more or fewer tectonic plates ...

A caldera is usually the remnant of a volcanic eruption powerful enough to collapse the structure surrounding the magma chamber. Many of our examples, like Yellowstone, Crater Lake, Toba and even ...

I've read the other answers relating to this area (and discovered to my disappointment that my great ideas have been done before... hey ho). But I'd like to get the science right. I have a nation of ...

I want to have an Earth-sized planet (with similar gravity) with an extremely low-density atmosphere (comparable to Mars) at most of its surface. Complex life, including an information-age ...

In my world, Southern Europe, Northern Africa and all the territories surrounding the Mediterranean belong to a single empire. The Emperor and his Council have decided that they are going to drain ...

The Black Sea is a brackish body of water, that used to be separate from the Mediterranean. Further back, it was likely part of the Mediterranean before the last ice age. How long would it, or for a ...

My current project features a contemporary scientist who is convinced that some sort of spacetime anomaly occurred in a tiny rural Yorkshire, U.K. community circa-1850; he believes a dilapidated old ...

Here is a map I just produced of the plate tectonics of a world I'm working on. Does anyone familiar with the subject see anything wrong with it? If you can differentiate between the penciled and the ...

A volcanic eruption is measured in two constants--gas and viscosity. For clearance, low viscosity is like squirting water off a nozzle, whereas high viscosity is like squirting caramel off a nozzle, ...

There is a lot of information on drying up a Mediterranean sized depression. However, there is not a lot of information on drowning such a large area or what sort of habitats could exist before the ...

One of the ways to create a major mountain range is a process called subduction. Here, heavy oceanic rock sinks beneath the lighter continental rock. The result--coastal mountain ranges like the ...

So in many a fantasy world mountains, or in some cases a particular mountain that play an important role in the story. Maybe it's the seat of the gods or hosts a hidden Shangri La, you get the idea....

Here is a link to the water canopy theory. My question is: how this water could end up there, high above the surface? I was thinking about two possibilities: a comet spreading ice/water as it ...

To expand the territory of the EU, one can consider recreating Doggerland by reclaiming the lost land from the sea: Had our ancestors had more technology, they could have dealt with the sea level ...

I'm currently working on a conworld that has never had any contact with Earth, and I'd like to create words for iconic gemstones, such as rubies, emeralds and sapphires. However, I can't help but ...

My question here is if there is any circumstance, however unlikely, that could lead to explosive nuclear fission that was not set off by intelligent creatures. I'm working on some bizarre planets for ...

How could the amount (total mass) of oxygen be increased on a planet like Earth (with a similar atmospheric composition), preferably by natural processes? For the sake of having a ballpark number, ...

Essentially, what would be the most efficient way of causing the Earth's core to cool as much as possible without damaging human civilization in any other way (the outcome can damage it, but not the ...

Say we have a planet, similar to Earth, which has deposits of a naturally occuring superconductor. Perhaps have it about as common as deposits of gold - Moderately rare, but occurs in veins as opposed ...

Thanks in advance for any input you can provide! I have a moon called Vieneo http://rise.unistellar.com/Vieneo which has some geological modelling of faults and epicenters over some range of time: ...

What could cause the continents to drift much faster than is today. I mean, much faster. Let's say it should take about 1-2 million years from this to this

So diamonds are the hardest natural substance, but can be broken/shattered by impacts. If a planet had a large mountain range made of diamond (maybe the size of the Rocky Mountains on Earth), would ...

I am trying to achieve the best possible accuracy for new planets, for determining landmasses and continents and then gravity, axial tilts, day length, tides, seasons and so, without going too deep ...

I want to create a convincing world where gunpowder is a rare and expensive commodity, allowing swords and plate armour to still be used effectively despite the world having current level of ...

If I were to use handwavium to raise a volcano in the middle of the sea, would it contain metals or ores large enough to be extracted by normal means, like mining with a pickaxe? Everything apart ...

So here's the picture, an island about the size of Sicily is on its own tectonic plate, it borders three other tectonic plates, it's separating from all of them at the exact same time. This is a ...

For my world, I would like a coastal mountain range that partway along its length is offset by a few (say, 100) kilometres, forming a pass through the mountains, like so: (N.B. I've drawn this very ...

I'm still fiddling with my map, and I got to thinking about continental drift. My world has two large large continents and a couple of other notable landmasses between the size of Iceland and ...

Far south-west of the main continent exists an island in a shape of crescent moon with dense jungles and slender mountain peaks and a single city named Kalt stands in a place where the islands' ...

BACKGOUND I’m working on a region for my world, and I have a very distinct idea of what I want the physical landscape to look like. Below is a description of what I'd like for the land, and an ...

I'm creating a city in a fantasy setting that has no magic in a medieval earth-like world. The city is located near a huge mountain range. It used to be a small city but grew large with relative ...

Our planet has a surface full of silicates and a core made of iron. It's due to this that Earth is the way it mostly is - most rocks and many minerals contain some form of silica. But what about a ...

I'm continuing to hash out the map of my world, using tutorials found on this site and elsewhere. In some tutorials the starting elevation levels of a planet are treated pretty randomly, implying ...

The Polar Pangaea

During the Permian and Triassic periods, all the continents had joined together to become the supercontinent Pangaea. Its size means that the majority of terrestrial life might have been confined to ...

I'm building a world with almost weekly extreme windstorms, driving the residents to either live underground or in the 'wind shadow' of sealed-off valleys. To sum up the windstorms' power, "You know ...

A friend of mine was telling me about a story where a man clear cut a diverse ecosystem of plants in an area similar to size and shape of a small caldera (not necessarily a caldera itself). ...

I thought that a large, close moon might help generate enough heat and stress to raise the average temperature on my world and stave off a Snowball Earth scenario. According to this article and this ...

I'm building a very small homeworld (0.602 M$_e$) with a very large moon (0.0711 M$_e$) that orbit each other at a barycenter about 7.12 planetary radii (1 R = 0.870 R$_e$) from the primary's center; ...

I'm continuing to work on my map, and one thing that's giving me difficulty is figuring out the geology of a region that I wanted to be similar to the Ethiopian highlands and African rift valley. This ...

This kind of ore should be rare (maybe from meteorites?), dangerous (radioactive?), but potentially very useful in a world where people have augmented abilities, cybernetic attachments, that sort of ...

So, for some reason the sun has randomly disappeared. The earth, along with the rest of the solar system, have been thrown out into interstellar space. Obviously, temperatures will plunge to levels ...

How can an ultra-deep hole or canyon form naturally on an earth like world? By ultra-deep I’m thinking something like the Marianas Trench but on land and not filled with water. If it’s not possible ...

BACKGROUND So I was working on a map, when I suddenly realized that despite the many helpful tutorials on this site I have very little idea what I'm doing. I thought it might be a good idea to put on ...

While the reasons for it's existence do not matter as it is part of an artificially created planet, I am curious if a lapis lazuli island would be able to survive erosion and support Earth-like life? ...

The planet in question is this one. Approximately three quarters the size and half the gravity of Earth, an atmosphere 25% as dense as the Terran one which mainly consists of Nitrogen with small ...
