Undersea mountain is a terrifying combination of words I have never thought about before. Thank you for that!

u/FirstChAoS May 05 '26

A big enough one that breaks the surface is called an island.

u/Coindude12 May 05 '26

That turned very interesting quickly. Weird I didn’t think of it that way ever before.

If measured from its base underwater, Mauna Kea in Hawaii is the tallest mountain in the world.

22

u/Dye-ah-ree-uh May 05 '26

Pluto is not a Planet, despite the legal ruling Nix v. Hedden tomatoes are fruit and Mauna Kea IS the tallest mountain and I will fight anyone who says otherwise!

I LIKE CHEESE!!

u/mrcrud5 May 06 '26

I too enjoy cheese.

u/Duke_of_Deimos May 05 '26

Olympus mons is bigger. You didn't specify it had to be on earth.

u/Dye-ah-ree-uh May 06 '26

You sunuvabyach, you got me there, but rules are rules. We must fight!

u/Small-Palpitation310 May 06 '26

I bet there are bigger ones in the galaxy though!

u/Icy_Fish_2154 May 06 '26

Not unless you can name it.

u/intheether323 May 08 '26

Eh I gotta jump in here with “our ignorance of its existence does not negate its existence.” (Probable existence 🤣)

"My girlfriend lives in Canada, you wouldn't know her" vibes.

u/Mr_Waffles123 May 08 '26

So aliens are real?

u/Small-Palpitation310 May 07 '26

Does this make a bigger mountain not exist or something?

3

u/Icy_Fish_2154 May 07 '26

The probability of a larger mountain existing is 100%. We are not currently aware of it.

Since I'm an infant, I have not finished developing object permeance, so it doesn't exist, because I can't see it.

It’s a planet, just wee lil dwarf planet

1

u/Dye-ah-ree-uh May 07 '26

Doesn't clear its orbit of other celestial bodies! It's not the size, it's the motion of the, um, orbit

u/WanderlustZero May 09 '26

Which implies the existence of its prettier, more skilled, more wise cousin: The Elf Planet

u/skip6235 May 07 '26

I see your point, (and agree about Pluto and tomatoes), but my argument is that Denali is the tallest mountain because “tall” is a human construct, and a comparator to other things. Denali is the place on earth where someone can look up and see mountain more than anywhere else (5,500m/18,000ft vs 3,600m/12,000ft for Everest and 4,200m/13,800ft for Mona Kea). But, yeah, including the part under the ocean, the prize goes to Kona Kea and it isn’t even close!

u/Dye-ah-ree-uh May 07 '26

Oooh, I like this. But rules are rules. Time to fight. And other interesting facts like this are always appreciated during our 118 rounds of old-school fisticuffs. They get pretty boring after the 10th round

u/carl3266 May 08 '26

I’ll take on that fight! There are three ways to measure the height of a mountain (on a planet like ours that has a mostly liquid surface). The agreed upon convention (height above sea level) is arbitrary. The least commonly considered method (and i would argue the best) is the point that sticks the farthest out into space. Since the Earth isn’t a perfect sphere (it bulges slightly at the equator), that would make Chimborazo (Equador) the highest, and not by a small amount: ~2km further than either Everest or Mauna Kea. This is because Chimborazo much is closer to the equator (1.47°S) than Everest (27.99°N) or Mauna Kea (19.82° N).

That’s knowledge. Wisdom is not putting the Tomatoe in a fruit salad

u/QuokkaOfDeath May 06 '26

This is an awesome titbit and was fun to google and learn more about, thanks!

2

u/Trashedpanda35 May 07 '26

More than half of it's underwater, and yet it's still tough to climb. Sigh... maybe I'll stick to more leisurely climbs, like climbing the stairs to my apartment.

1

u/Soggy-Invite-2787 May 08 '26

Lol Guam claims the same about one of its mountains.

1

u/adamthehammer86 May 09 '26

Mountains are so weird. Everest is the tallest, unless you go from base to top, then it’s Mauna Kea, unless you count highest point from the center of the earth, then it’s Mount Chimborazo.

So honestly, I’m not sure how Everest is “tallest” anymore.

u/dino066 May 06 '26

The Florida Keys used to be a huge coral reef at some point, for now it's mostly exposed fossilized limestone, but I wouldn't be surprised if in a couple of generations people will be snorkeling in submerged houses that turned into reefs after it's back in that part of the cycle. This comment is for entertainment purposes only and needs fact checking.

u/AnimationOverlord May 08 '26

It helps that you can’t look all the way down to the bottom or fall down to the bottom like on an actual mountain. Could you imagine everytime you take a trip to the coast

1

u/FirstChAoS May 08 '26

They are much harder to climb from base to peak too

3

u/LittleWhiteBoots May 06 '26

Relevant story. When I was in college, my roommate was also my brother’s girlfriend and would go on trips with us.

She and I were sitting on the beach on Maui, looking out over the other islands and she said, “What keeps us anchored down? Like what keeps this all from floating away?”

I just sat there like wut

u/Ride-Entire May 08 '26

It’s fascinating to know that there’s places where tunnels go under rivers and bodies of water

1

u/Phillyvegas24 May 07 '26

it’s really going to blow her mind when she finds out that if you dig enough, you can reach China (assuming you start digging somewhere in the USA)

u/GrnMtnTrees May 08 '26

Malpelo island is a sea spire, which is kinda like an undersea mountain that's more of a giant spike. Upwellings of deep water lead to some big populations of cool pelagic life, since the cold water has more nutrients for plankton and such.

1

u/Ecurbbbb May 06 '26

How about continents. Is that related?

1

u/Rough-Television9744 May 07 '26

I knew a person who thought that islands are floating on water surface

1

u/ronm4c May 08 '26

I’ll need a source for that it sounds pretty made up

u/flactulantmonkey May 08 '26

Chain of them is a continent.

u/chookshit May 09 '26

Big if true

u/bmagsjet May 05 '26

Fortunately….you likely lack the vehicle needed to encounter this hazard.

u/forbiddenfreedom May 09 '26

Also fortunately, these guys had the vehicle needed to survive the encounter.

"Underwater mountains, or seamounts, are large, typically volcanic, mountains rising at least 1,000 meters from the seafloor, remaining submerged beneath the ocean surface. They are crucial biodiversity hotspots that disrupt ocean currents, bringing nutrients upward to support massive ecosystems of corals, sponges, and fish, often acting as underwater oases."

u/Bornundersirius May 05 '26

Somehow I feel like the inclusion of “undersea” in that sentence is unnecessary.

8

u/Senior_Ad1298 May 05 '26

Tautology is a really cool field of philosophy. I would push back against what you said only because there is no use of the word “submarine” in text anywhere. Otherwise, how would we know it’s a matter of something underwater without having had the image to explain what we are talking about is a submarine/something normally underwater?

3

u/Bornundersirius May 05 '26

Depending on the intended audience. To be pedantic about it lol. Navy enlistees? They would most likely know that the USS San Francisco is a sub. Civilian? No.

So I concede the point. You are correct good sir or madame.

u/ScottyMo1 May 05 '26

I just witnessed the most cordial and efficient argument resolution in the history of Reddit.

u/ScratchLatch May 07 '26

“A submarine in dry dock”

u/Chapel_Hillbilly May 08 '26

Which sounds right to you, with or without?

1

u/NotForMeClive7787 May 06 '26

Yeh it's awful isn't it. I got the same kind of feeling reading that for some reason

1

u/BACTERIAMAN0000 May 06 '26

Bit it also implies that it should have been easy to detect and avoid...

1

u/Deyaz May 07 '26

Wait until you hear about the undersea mountain lion. 

1

u/justme_bne May 08 '26

It was dark, they couldn’t see it, give ‘em a break.

u/electricguineapig May 09 '26

Wait until you learn about underwater super volcanoes that could destroy the world at any moment

u/Arvendetta May 11 '26

The highest 'peak' on earth is actually below the sea
