Between water molecules a big cohesion force exist; this is the cause of the high surface tension of water.

Cohesion, surface tension, and adhesion are all properties of water that stem from its ability to form hydrogen bonds between water molecules. Cohesion refers to water molecules sticking to each other, surface tension is the result of the cohesive forces at the surface of water, and adhesion is the attraction of water molecules to other substances.
Cohesion, surface tension, and adhesion are all properties related to the interaction of molecules in liquids. Cohesion is the attraction between molecules of the same substance, surface tension is the result of cohesive forces at the surface of a liquid, and adhesion is the attraction between molecules of different substances. These properties all involve the forces that hold molecules together in a liquid.
Cohesion: When things stick to each other (WATER) Adhesion: When things stick to other things (ALSO WATER) Surface Tension: a property of the surface of a liquid that causes it to behave as an elastic sheet. Think of it as the thing that helps insects to glide along the water. (ALSO WATER)
capillary action is a common consequence of surface tension.
reference point
Earth's surface is a common reference point for detecting motion.
I believe all liquids have intermolecular forces of attraction between the molecules, whether they are small forces such as dispersion forces or stronger ones like hydrogen bonding in water etc. When in, "Bulk" such as in the middle of a liquid (not the surface) these forces are experienced all around the molecule in equal amounts and therefore no net force is experienced. However, at the surface of the liquid there are no attraction forces from above and so the molecules experience a net downwards pull. This causes the molecules at the surface to be pulled into the liquid, compressing the space at the surface. This smaller, denser and more packed surface is what causes the surface tension...correct me if I'm wrong. :)
Earth's surface is a common reference point for determining position and motion.
Water has the highest surface tension of common liquids at room temperature. This is due to its strong hydrogen bonding, which creates cohesive forces between water molecules that pull them together and give water its high surface tension.
Surface tension is measured by determining the force required to break the surface of a liquid. Common methods for measuring surface tension include the drop weight method, the capillary rise method, and the maximum bubble pressure method.
Cohesion in real life can be observed in various contexts, such as the way water molecules stick together, forming droplets and enabling surface tension. In social settings, cohesion is evident in strong community bonds where individuals support one another, enhancing group solidarity. In teams, cohesion manifests as members work collaboratively towards common goals, fostering a sense of unity and shared purpose. Additionally, in literature, cohesive devices like repetition and transitional phrases create smooth flow and clarity in writing.
