There are a few things classified as deltas. Like airplanes and computer monitors. Which are you talking about
Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.
Surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. ... it also helps water to move up the xylem tissue of higher plants without breaking up
F. Cohesive behavior.
This is the unification of similar molecules within the molecular structure of an organism.
