Answer :
quicksand is formed when regular sand, or mud or gravel comes in contact with a flowing water source, usually an underground stream.
The flowing water flows in between the particles of sand and acts as a lubricant to reduce the friction.the sand particles get suspended in water and sand changes into liquefied state.As long as the water flows,the quick sand bed will exist.
