Answer:
What comes once in a year twice in a week but never in a day?
I start new then become old. Start clean but be one dirty. I usually start big then become little.
I shift around though always slowly. I never move more than a few inches at a time. A large movement by me can kill many people. I am huge yet unseen by humans.
I’m tall when I’m young. I’m short when I’m old. I can light up your world. What am I?
I dig out tiny caves and store gold and silver in them. I also build bridges of silver and make crowns of gold. Sooner or later everybody needs my help yet many people are afraid to let me help them.
