Informal learning is the unofficial, unscheduled, impromptu way most of us learn to do our jobs. Informal learning is like riding a bicycle: the rider chooses the destination and the route. The cyclist can take a detour at a momentâs notice to admire the scenery or help a fellow rider.
The name mica is derived from the Latin micare, which means to glitter or also to shine. Mica is a naturally occurring group of silicate minerals that has a perfect basal cleavage, easily splits into thin luminae, and is most often translucent in appearance.
Mica Minerals. Mica minerals make some rocks sparkle! They are often found in igneous rocks such as granite and metamorphic rocks such as schist. They sparkle because light is reflected on their flat surfaces, which are where the mineral breaks along its plane of cleavage.
