Big Brain Answers

Question from K. G. Fresno, CA
Dear Big Brain: What is dirt made of and where does it come from?
Answer: I'm glad you asked. Dirt seems to be made of some brown material of unknown origin. As to where it it comes from, that's easy, its always been here. Thanks and have a nice day.
