The mantle is a large part of the Earth’s volume and even though it flows over geologic time scales, it is still considered solid. Then there’s the crust and inner core, which are also considered solid. IMO the Earth is closer to a balloon filled with flour and a small iron ball in the center.
I believe this is also related to your question (the pitch drop experiment) but im too sleepy to integrate this to my answer above lol
The surface is mostly covered in water, but compared the total volume of spherical earth, there’s fuck all water.
Was referring to the stuff under the crust as the liquid not the water on top
Metric fuck all, or is that freedom units?
Oh look! A Wikipedia article that answers that.

Of course there’s theories out there that say there’s a lot more water in the earth than we’ve been able to calculate.
Real answer is that our best educated guesses are still that.
