Question

What causes a water strider to be able to walk on water?

1. Adhesion
2. Surface Tension
3. Cohesion

Answer 1

Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water.

Hope this helps! (:

Answer 2

By repelling water, the tiny water striders stand on the water's surface and the captured airs allows them to float and move easily. so number 2. Surface Tension.

Step-by-step explanation:

The attraction between water molecules creates tension and a very delicate membrane. Water striders walk on this membrane. ... The legs have tiny hairs that repel water and capture air.
