Answer:
I build up castles. I tear down mountains. I make some men blind, but I help others to see. What am I?
My first is in window but not in pane. My second's in road but not in lane. My third is in oval but not in round. My fourth is in hearing but not in sound. My whole is known as a sign of peace. And from noah's ark won quick release.
I am milky white and scares people.
I am good at concealing what's real and hide what's true. Sometimes I bring out the courage in you!
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.
