Raindrops are not shaped like water droplets. They are formed by the cohesion of water molecules, which is based on surface tension. When the surface area of a raindrop is small, it tends to be spherical. However, as raindrops become larger, they are more likely to be influenced by air currents, resulting in a shape that is rounded at the top and flattened at the bottom. Therefore, the shape of raindrops can vary greatly.
