Answer
Surface tension results from hydrogen bonding in water molecules thus water molecules are held together by force making the water surface appear like a web. The force of attraction between water molecules is called cohesion force, and this nature of the surface gives water two major characteristics to interact with the earth; the first is it makes water surface as though it is a stretched smooth surface, and the second is that it makes whole water as one compact of molecules held together. the first characteristic is one that helps insects walk on water and the second helps water move up xylem tissues of higher plants as one column.
