Here's a breakdown:

* Resin: This is a sticky, aromatic substance that trees produce to protect themselves from injuries and pests.

* Coniferous trees: These are trees that have needles instead of leaves and produce cones. Examples include pine, fir, spruce, and cedar.

The process of making turpentine involves extracting the resin from the trees and then distilling it. The distillation process separates the turpentine from other components of the resin.
