As clouds cools down and "rain" forms, it starts to drop. As it drops, large liquid groups are broken by air resistance to smaller pockets, and so on, until a rough spherical shape is formed. This provides the drop not with the least amount of surface tension/wind drag/air resistance, but the highest possible resistance that the surphere can withstand without "overtaking" the attraction of the water molecules. If the resistance continues to drop, the rain drop may decrease further in size until it reaches a shape which the resistance is terminal, or that it reaches terminal velocity.

Because of atmospheric pressure and difference in density of the two mediums.These two combined create a close to spherical raindrop...tom science

bcz of surface tension and the force of gravity>
this is also the reason of broken stars due to their velocity and the gravity fore of the other planets as their tail looks long behind them and the are like spherical from front!

They aren't. Surface tension causes them to form a shape with minimum surface area, i.e. a sphere. However air resistance builds up as they fall and flattens out the sphere shape.

l dont think it is spherical, it depends on where it dropped.

Because of surface tension

Hydrogen bonds. Water molecules contain two hydrogen atoms and one oxygen, and they can share hydrogen atoms. This sharing "bonds" the two molecules together.

they elongate as they fall through the air from speed and atmospheric resistance
