Water mountains are my new favorite concept

Wait I have a meme for this (and absolutely no one is surprised):

I think they’re onto something. In fact, these water mountains seem to be so common, it might just be one big water mountain that covers the whole planet, and is so big it eventually wraps around and meets itself at the bottom.

No no no. That would NEVER work! See, what’s actually happening is the lizardmen are driving these ships, and taking them to the pirate ports where they sell everything. Thats when they buy evrn MORE drugs, and Steve said I can have some of the drugs. So I started eating these gummies, but it turns out they’re just regular gummy bears. They’re still good though. I would trade you some of my gummy bears for some actual gummies, but I have misplaced my pants…

I have never met a flat earther, but if I did and she was hot I’d see what else I could convince her to believe.

Just a quick question.

How does one go about hiding a ship in a glacier?

Okay. Make that two questions.

Why does one hide a ship in a glacier?!

So that one day, the shape-shifting alien can thaw and gobble up the entire crew of a research station?

There are “hills” on the sea. I doesn’t prove that Earth is not also round.

TIL, thank you

Yep. This is due to variations in the gravitational magnitude at any point from the earth, moon, sun, and other bodies, as well as the periodicity of the earth/moon/sun rotations interacting with friction (between the sea and the sea, the sea and the atmosphere, and the sea and the lithosphere), and creating a giant standing wave (which is constantly changing, like an instrument or a musical composition) of ocean water all over the earth. This doesn’t even take into account atmospheric pressure and water temperature/viscosity variations. The earth is a complex system with waves upon waves upon waves of interacting coupled oscillations all interfering with each other. Whoa 😳

Somebody way better at music should find a way to turn that into music.

Always amazed me how such insignificant creatures, bacterium on the scale of the earth, can have such a big impact on the environment.

Phytoplankton produce 50-85% of all the oxygen on Earth, and cyanobacteria did even more before them. Before all this free oxygen could float around in the air, all the metals in the ocean had to be oxidized, which is where the massive banded iron formations come from, and then all the minerals in the crust had to oxidize too. Every layer of Earth’s surface was radically changed by this, taking a billion years and likely prompting the evolution of eukaryotes.

And more. Major river discharge can raise the sea level in the area. Then big circular currents similar like when you stirr your cup of coffee or tea. Or chocolate milk 🤤

Isn’t that how tides work? The hills move? I’m probably all wrong

It’s all about gravity and then some.

The tides and ordinary waves caused by wind will appear as moving hills.

The daily tides happen from the moon pulling the water towards the line between the moon and earth. This forms the tides that go around the globe everyday. It happens on both sides of the globe, like this:

The topological map shows something else than tides and moving waves though.

The globe isn’t perfectly round. It’s shaped like an irregular geoid, almost shaped like an ellipsoid, but not exactly. The ocean surface topological map takes the usual tides in account and maps the surface in relation to the geoid, so it shows where the water level is higher or lower than it would be if it was perfectly distributed.

The earth’s gravitational field is not perfectly regular, so it will pull more water towards certain areas, and there are things like ocean currents and the regular trade winds happening from Earth’s rotation, all shaping the sea in hills and valleys that are not just waves. These variations span large areas and doesn’t appear as much in relation to the tides. It basically just goes to show that sea level is not at all level. For instance, the east coast of USA has a higher sea level than the west coast. If sea levels should rise from melting ice, it is therefore more likely to spill over the east coast than the west coast.
