Hydrogen Bonding is a not very strong bond between two molecules resulting from a proton in one molecule and an electronegative atom in the other.
One of the properties of water is that is has high surface tension. This means that the molecules are sucked in and create a sort of plastic barrier or skin around the water. Without this tension, even the smallest objects would sink underwater, for example, even the small particles of dust would sink causing death of the marine life, also causing the ecosystem to fail. This property also allows water to be “pulled up” by plants from the ground, which helps them to survive.
Overall, high surface tension, besides form being incredibly interesting, it is very important and necessary for the natural course of nature to go well.
