I would say that the size of raindrop determins the shape along with the amount of gravity!!!
Surface tension
The wind if it is windy the drops explode on the way down to Earth full size raindrops are mostly seen with very little Wind.
Spherical to tear-drop shape. The latter is the most hydrodynamically efficient, forced by the falling drop's slipstream, with a spherical-cap nose tapering back to a pointed tail.
The mineral composition of the conglomerate determines the grain shape as well the the type of weathering or erosive elements (wind, water, chemicals) that the rock is is exposed to because grain shape is heavily dependent upon whether the rock has been subjected to erosion or not.

No really. The shapes is a matter of physics.
No, they want to be round but get stretched into different shape as they fall by air resistance. Thus raindrops actually do not keep their shape, and they are also not tear-dropped shape. A raindrop starts as a rounded or spherical shape. As it falls down it will eventually lose its shape. It changes shape due to surface tension, speed, and the pressure of the air. Raindrops tend to end up a spherical drop of water.

The container determines the shape.
Raindrops are Round...At First.Raindrops start out as round high in the atmosphere as water collects on dust and smoke particles in clouds. But as raindrops fall, they lose their rounded shape. Instead, a raindrop is more like the top half of a hamburger bun. Flattened on the bottom and with a curved dome top, raindrops are anything but the classic tear shape. The reason is due to their speed falling through the atmosphere

when a liquid is placed in a container it takes the shape of the container. raindrops and teardrops are a shape that liquids have when you use a dropper, when drops of water fall from a faucet
The gene sequence determines the codon, which in turn determines the aminoacid, which in turn determines the tridimensional shape on the protein, which in turn determines the shape of the active site, which in turn determines what it'll be catalysing.
Gravity, which makes them fall down. Wind can also affect the direction somewhat.
