Fossil homework 9/21



The second picture is a mammoth. It was preserved by being frozen or being barred in the mud or sand.  All of the remains were copied and molded like casts giving the rock its texture and shape. They replaced the remains withs molds.


The first picture is the fossil from its original remains from when it was alive. We got the fossil from it being preserved and frozen in the ground.

Relative dating homework 9/17


3, 2, 5, 4, 6, 1

I think its in this order because number 3 and number 2 intruded the other layers. Number 3 is the oldest because it goes through all of the layers and number 2 just goes through a few layers. The next youngest is number 5 because it is the next one at the bottom. The next layer is number 4, 6, and then 1.
