When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

Capillary Action is key for

• Water moving from roots to leaves in plants

• Air moving from mouth to lungs

• Ice floating on water
