Arrange the rock and layers from oldest to youngest. We examine the rock outcrop‘s if you need to. Record the order in the student guide.

Sedimentary rocks are normally laid down in order, one on top of another. In a sequence, the oldest is at the bottom, the youngest is at the top. This is the principle of 'superposition'.

Explanation:

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)

more words for this could be abiotic and biotic

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
