Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?

a)

The insects are light enough so they do not break the hydrogen bonds holding the water molecules together

b)

The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.

c)

The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
