    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

    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

    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.
