How do you like the Riddles?

What can travel without moving? Time What has a lock but no key? A diary What has a bed but never sleeps? A river What comes down but never goes up? Rain What has teeth but doesn’t bite? A comb What has keys but can’t type? A piano What is always behind you but can’t be seen? The past What has one eye but can’t see? A needle What can fill a room without taking space? Light What is black when clean and white when dirty? A chalkboard What has an eye but cannot cry? A needle What can run but never walks? Water What has a face but no mouth? A clock What is easy to lift but hard to throw? A feather What can you hear but not see or touch? Sound What has a foot but no legs? A mountain What has a ring but no bell? A phone What breaks when you say it? Silence What has keys but opens no doors? A keyboard What gets wetter the more it dries? A towel What has words but never speaks? A book
