9/20 Blog Homework Layers of Rock
I think the order in which the rocks go from oldest to youngest are 2,4,5,6,1,3. I think 2 is the oldest because it is the one that starts at the bottom but goes up a little. Then I think it goes 4 because it is a embedded fragment in between the other rocks around it. I also think 5 is an embedded fragment but because 5 is above 4 I think that means 5 is younger. After 5 I think it goes 6 because it is one of the layers closest to the top giving me a sign it is younger. Then I think the youngest rock layer is 1, because it is at the top and you could see it if you looked at the ground right now giving me a sign it is the most recent. Finally I think it is 3 because 3 is a Intrusion. And because intrusion is molten rock that has found its way upward it is most likely the youngest of all the layers.
