Water and Ice Side-by-Side

In liquid water each molecule is hydrogen bonded to approximately 3.4 other water molecules. In ice each each molecule is hydrogen bonded to 4 other molecules.

Compare the two structures below. From observing these two structures can you explain why ice is less dense than water?
