Detailed explanation-1: -The surface of any body in water behaves as though it is covered with an invisible skin, which allows small, light-weight insects to walk across it. This skin effect is caused by surface tension. Like molecules are attracted to each other. They like to “stick together” and this attractive force is known as cohesion.

Detailed explanation-2: -Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

Detailed explanation-3: -Answer and Explanation: Some tiny insects are able to walk on water because of the surface tension on the top of the water that is due to water’s cohesive properties. Water is cohesive, or ‘sticky, ’ because water molecules are attracted to each other, due to the polarity of the molecule.

Detailed explanation-4: -Insects can walk on water because of a phenomenon called surface tension. This is essentially a property of water (or any liquid) which allows it to resist an external force.

Detailed explanation-5: -Water striders are small insects that are adapted for life on top of still water, using surface tension to their advantage so they can “walk on water.”
