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 ...

I'm working on a earth-like planet with a much lower sea level (like 3000m so the mid-ocean ridge would form many islands) but is that even possible? Will the emerged ridge make some weird stuff and ...

The capital of a country is built on a series of stone hills that gradually lead to the ocean. The stone is noted for both the strength of castles made from it and its unique blue-green coloring. This ...

I have a super-earth world. The surface of the world is shallower due to extra gravity, so shorter mountain ranges and less ocean depths. The world orbits a binary star system at a distance of the ...
