The surface is mostly covered in water, but compared the total volume of spherical earth, there's fuck all water.

There's a difference between water and liquid.

Not sure if the solid core has more mass than the mantle.
In any case, I'd say it's like a balloon with something solid floating in the middle.

Was referring to the stuff under the crust as the liquid not the water on top

[–] Tolookah@discuss.tchncs.de 6 points 1 month ago

But how liquid is the molten core? (I assume that's where this poster was going)

[–] LostXOR@fedia.io 22 points 1 month ago (1 children)

Technically speaking, no. The mantle, which is solid, comprises about 2/3 of the Earth's mass. However at a planetary scale solids are not rigid enough to maintain their shape, so the Earth is closer to a liquid held together by gravity than to a rigid solid object. See this simulation for an interesting demonstration of its properties: https://youtu.be/kRlhlCWplqk

So it's like a water balloon full of dust/sand?

What I'm hearing is shepherds' pie, but spherical

I should get something to eat.

Depends upon how you're seeing liquid. If you just mean water, definitely not. If you mean things that behave like liquids behave or are in their liquid phase (is magma liquid here?) then I'm not sure

Nah, it’s more like a wet baseball. Only 0.02% water by mass. Source

Edit: My bad, you asked about liquid, not just water, so this is less relevant but I’ll leave it as some trivia.

I was referring to the stuff under the earths crust not the slime on top :P

Hey watch it, I’m 70% slime!
