Yes and no.

Moisture is the main factor and any air has moisture in it. It is all about surface area. The more surface-area is exposed to air the more moisture it will attract. To a certain point the granules have extra exposed surface but as soon at the top layer is saturated and hardened into a crust it protects the powder layer below.
