Identify the order that the environmental conditions of this location occurred, (1) was the longest ago, (5) is the most recent.

deposition of sedimentary layers (9 & 10)

earthquake creates a fault line (7)

erosion (12)

deposition of sedimentary layers (3, 4 & 5)

volcanic intrusion (11)

1 deposition of sedimentary layers (3, 4 & 5) 

You can see that these layers are at the bottom and following the law of superposition the deeper the layer is the older. So out of all the layers, 3,4,and 5 are the youngest layers. 

2 earthquake creates a fault line (7)

The earthquake fault occurred next because as you can see, the fault cuts through layers 1 - 5 and stops before layer 8. And if you noticed layers 1-5 are shifted and this happened because a fault was created after they formed. 

3 deposition of sedimentary layers (9 & 10) 

4 volcanic intrusion (11)

It comes after layers 9 and 10 because the intrusion cuts through it. 

5 erosion (12)

Geothermic gradient is the rate of increasing temperature with respect to increasing the depth in the earths interior. away from tech tonic plates boundaries, it is about 25-40 c/km (72-87 degrees f/mi) of depth near the surface in most of the world.
