Small scale fading and large scale fading

Web(1) Shadow fading is called slow fading because the duration of the fade may last for multiple seconds or minutes. If the obstacles are still between the transmitter and receiver, why would the fade last only up to minutes, instead of forever until the obstacles are gone?
