Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity?

Probably not Roman or post-Roman overshot, breast, or undershot (i.e. classic) water wheels, but what about reasonably modern hydro power installations? First, you would need to define the energy ...

What effect do caves have on music played in them?

I play drums in my free time, so first hand experience: playing drums in the open has the advantage of carrying the sound away (maybe your neighbors will see it differently) without the problem of ...

Is it possible for an artesian basin to go underneath a shallow sea while still being freswater?

There is one point which I see as a big no no with respect to what you describe: the area underneath one of those mountains is a subduction plate boundary. This is a simplified tectonic map of the ...

Is it possible for an artesian basin to go underneath a shallow sea while still being freswater?

In the seventies, the London-Brabant massif was thought to have an aquifer that spanned the English Channel / La Manche in this way. It probably doesn't. It is possible, but for the reasons cited in ...

What effect do caves have on music played in them?

The reverberation inherent in the caves is not a problem if your music has tempo and beat on a timescale longer than the reverberation. This is why one can play slow harmony transitions all day long ...

How would humans evolve if they began living underground?

You scenario poses a LOT of problems just living there without worrying about evolving. We get vitamin D from sunlight amongst other things, so you need a good source of that. A good source of food ...

Geology and tidal forces on moon with Earth-life surface, but very unstable underground

Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity?

This is a Frame Challenge The water source isn't the problem, it's channeling that source to a useful location. Whether your source is an underground river or an aquifer, it doesn't matter. Frankly, ...

Sure it is, it all depends on the scale of the "caves" these creatures live in. In many worlds these creatures live in underground dwellings with cavities that rival our largest cathedrals ...

What effect do caves have on music played in them?

Think of the cave as a contributor to the music. Every chamber has its preferred tones and resonant frequencies. If you play music, including drums, inside a cave, the cave will play along with you. ...

They would do their music in designated recreation areas for it, where either the acoustics are naturally (or with some help) excellent. Or where there is a huge cavern that makes it viable without ...

Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity?

Aquifer has no usable potential energy. Underground river unlikely to have much of a flow but if you have it, water has the way out without filling up your big cave, so you can just drop any water on ...

What effects to expect from 100+ generations living subterranean with constant low doses of radiation

This depends on the star. Suppose you are on a planet orbiting a red dwarf. The planet is probably tidally locked to the star, so people will live in the twilight zone, making the most of the heat on ...

There is food under mountains and it caves- but it comes from either the surface. (Swept in plant material, fish etc. via streams). Or it comes from parts of the mountain (coal, oil) which once were ...
