"It's the reason a drop of water has a spherical shape."

Explanation: Surface tension is the pull of molecules at the surface that minimizes surface area, making drops bead into a sphere. The other statements are false: ice floats because solid water is less dense, freezing involves hydrogen bonding, and road cracks come from freeze–thaw expansion, not surface tension.
