Answer:
I build up castles. I tear down mountains. I make some men blind, I help others to see. What am I?
I can be winding and I can be straight. I can be smooth and I can be rough. Sometimes both. I start out black but fade to brown. My favorite colors are yellow and white and I love stripes and dashed lines.
I'm the source of all emotion but I'm caged in a white prison.
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.
Everyone has me except for a few. You may not be able to identify me but I can always identify you. What am I?
