This is the map of our Permian from 300 to 252 million years ago: As you can see, (nearly) all of the continents had joined together to create one massive landmass called Pangaea. To the sharp ...
Since the geological history of the world's largest nation is as big as the nation itself, and since I don't have a master familiarity with Russia's formation over hundreds of millions of years, I'...
Anyone who has a well-versed background in geology will know that the rock of the continents is granite. It forms as lava cools down very slowly, creating large minerals and crystals that shield...
North America's largest and perhaps most popular volcano is the plume of mantle situated right beneath the surface of what we arbitrarily call Yellowstone National Park. This image shows the two...
(Before anyone asks, this is related to the Sahara, Makgadikgadi and Himalaya questions.) The Sahara may take credit at being the hottest desert, but the Australian Outback is hardly a pushover by...
In popular mythology, wearing a garlic wreath is a good defense against vampires. Silver kills werewolves. But why? How could garlic, a spice whose only offense is plain stink, deter an attracti...
Back home, there are three factors to consider: Mont Forel, Greenland's tallest peak, can be found in coordinates 66.9333° North and 36.8167° West The Arctic Ocean's average depth is 3406 feet,...
I am currently at the end of my wits. No matter what change I do to the North American geography, northeastern Nebraska (42.4649° North, 96.4131° West), is still in the danger zone called Tornad...
Long ago, I asked for a kind of steel alloy under an alternative recipe. Right now, the list is as follows: Carbon (2%) (Reasonable material and amount) Chromium (12%) (Reasonable material a...
In this alternate scenario, only the Rocky Mountains and the Appalachians stand firm in the United States. Even so, some differences apply. The Appalachian Mountains (right) have grown to as tall...
The geographical features that make New York stand out from any other of the United States--Long Island, the huge boulders scattered in the city and the Hudson River, deep enough for barges to pass...
In this alternate scenario, there is a clear ecological distinction between broad-leaved deciduous trees and coniferous trees based solely on altitude. The broad-leaves and other angiosperms are t...
In this alternate scenario, five million years ago, a mass extinction hit Earth. Not a massive volcanic eruption or a devastating bolide impact, but a sudden cold snap, a transition from Miocene h...
I have just found out that the Milankovitch Cycle, a machination responsible for the creation of the Pleistocene ice ages, has its part played partly by orbit from the entire solar system. As a re...
What I mean to say is that the Black Death of the 14th century still devastated Europe, but the culprit in this alternate scenario is not Yersinia pestis, the bacterium believed to be responsible f...
On Earth, there are only two different ways to create major volcanoes. One way is subduction. It occurs when older/heavier rock sinks beneath younger/lighter rock. As the rock descends, it lique...
Domestication of otherwise wild animals go way back. Cats have been our best weapons against rodents for 10,000 years. We had been breeding sheep and goats for their milk and mutton for almost as...
I live in northeastern Nebraska, and I had seen more than enough of tornadoes in my lifetime. So in an alternate Earth, it is my hope to make some changes that would save my home from being anothe...
The definition of a dragon depends on who you're asking. We are so used to the fire-breathing, bat-winged, avaricious antagonists of Europe and the long, lank wise men of Asia that we don't often ...
In this alternate Earth, there is a clear ecological distinction between trees depending on altitude. The lowlands are exclusive to broad-leaved deciduous trees while conifers can be found only on...
The popular image of a mermaid is a half-fish, half-human creature breathing fine above and below the surface. The only real-life analogy to this are the amphibians - frogs, toads and salamanders. ...
In this scenario, an underwater city is a collection of domes interconnected by tunnels 17 feet wide and 17 tall. The largest of the city's domes is 71,000 square feet in area and 137 feet tall. ...
The mountains of the American West have some major differences. For starters, only the Rockies stand firm"”no Coast Range, no Grand Canyon and most certainly no Sierra Nevada. The Rockies on Great ...
During the summer months, Tibet warms up like a hot brick, drawing in moisture from the Indian Ocean, and that explains why India is the wettest nation on Earth. In this alternate scenario, Tibe...
This is the Alps back home, cornering the Italian Peninsula and dominating the nations of Switzerland and Austria. The tallest, Mont Blanc, stands 15,780 feet above sea level. In this alternate...
