This week you got ice cream with your friends on Monday evening, had soccer practice on Tuesday night, gym class during school on Wednesday, and had a pizza party at school on Friday. You think you left some money in your jeans from Monday so you back through your dirty clothes hamper to find the money. According to the Principle of Superposition, in which order will you find your clothes in your hamper from the top to the bottom?
Shirt with pizza sauce stain, smelly gym clothes, soccer jersey, jeans with money
What is the Law of the Superposition?
In horizontal rock layers, the older layers are at the bottom and the younger layers are at the top.
