Drag each tile to the correct box.
Arrange the layers in order from youngest to oldest.

7,8,6,5,4,3,2,1

Explanation:

Working backwards (to get the oldest), we have layer 1 forming first, then 2 above it, then 3. 4, 5, and 6 formed and then a fault caused the right side to slide down. 8 is intrusive, you can tell it's newer than 1, 2, 3, 4, 5, and 6 because it reaches all of those layers. You can tell 7 is the youngest layer because it formed after the fault (it's not split like 4, 5, and 6) and after 8's intrusion (because 8 doesn't reach it).

"doesn't reach it" means it isn't in that layer.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
