Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some insects and small organisms can walk on water due to
A
Adhesion
B
Capillary Action
C
Surface Tension
D
Specific heat
Explanation: 

Detailed explanation-1: -Water striders are able to walk on top of water due to a combination of several factors. 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-2: -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.”

Detailed explanation-3: -Small insects such as the water strider can walk on water due to which phenomenon (Choose the best one)

Detailed explanation-4: -As it turns out, the bug’s feet are covered with waxy hairs that are “hydrophobic"which means they chemically resist contact with water. This combination of strong surface tension and water-resistant feet is what lets our bug stand on the water, without even getting wet!
