Objects in material design possess similar qualities to objects in the physical world. In the physical world, objects can be stacked or affixed to one another, but cannot pass through each other. Objects cast shadows and reflect light.
Shadows provide important visual cues about objects’ depth and directional movement. They are the only visual cue indicating the amount of separation between surfaces. An object’s elevation determines the appearance of its shadow.
