Overtime, a household freezer will develop a layer of ice that coats the inside an grows thicker over time. describe what happens to cause this layer of ice to form and grow.

The moisture in the freezer will freeze due to the cold temperature, and form a layer of ice (the water molecules expand and solidify). Each time the freezer is opened, the moisture that enters via the air will freeze and form a layer of ice on top of the previous layer, causing the ice to grow thicker over time.
