Fluid & Rigid Spheres

Wai: Hawaiian for water
Koa: Hawaiian for bold

I didn't expect that a falling raindrop inflates into an umbrella form and explodes into droplets, but it does.

I didn't expect that a waterball could contain and retain a central air bubble in microgravity, but it can.

Nature does not always conform to expectations.

I always thought that earth had a central dense rocky core, but now I'm not certain, it may be more like a turtle egg, hard shell, soft center or even gas-filled center (small or large). Earths' crust has floating tectonic plates like ice floes, floating on magmasphere, with hydrosphere floating on much of the crust.

Spheres are funny, a rigid and fluid sphere are quite different, one packs together like oranges in a basket, the other conglomerates into a single waterball in microgravity or puddle on earths' surface.

What seems rough is smooth at another scale in rigid structures with straight bonds, but fluid water has no scalar difference, always spherical with curved surface bonds even at the subatomic level I guess, depending on ambient pressure and temperature and material.

Volcanic soil: New magma rock cools, crystallizes, erodes. Silt crumbles downslope, washes downstream. Plants started as ocean phototsynthesizers, some moved to shallow freshwater, some to soaked soil, some to moist soil. Plant roots anchor, support, evapotranspiratively suction mineralized water up via capillary action, exchanging with air at leaf pore surfaces, release water, O2, CO2 and phenolic resins.
