Was just wondering if anyone could provide insight as to why when I
scan the posted Seattle Center ATC approach and departure frequencies
on any of my mobile or base scanners I can only pick up transmissions
from the aircraft and not ATC?

Thanks!

Because FM band is a "Line of Sight" communications band.
If you're close to wherever the ATC facility is (you can see it) you
should get all transmissions.

HTH.
