Shape of a raindrop. Low Pressure. Because air pressure exceeds surface tension, raindrop begins to break into smaller droplets by a number of process. High Pressure. Flow direction of a raindrop. Less air pressure thus flattens bottom and sides bulge. Flow direction of a raindrop.

Flow directionof a raindrop Raindrop retains its spherical shape due to its water surface tension.
