Okay, so we are in chapter 46, problem three, and we're looking at why is the pacific northwest covered in lots of evergreen forests? and so one thing that a forest needs is lots of water to support the trees, right? so that's what sort of separates a forest from like a grassland, is that it needs lots of water.

And so if we're in the pacific northwest, that means we're, we're on the coast and so there's going to be these nice mountain ranges right so these mountain ranges and and here we say have the ocean here's the ocean so what's going to happen is the winds coming up off the ocean are going to hit the mountain range and will rise and as they rise they they sort of collect and release water right so they're going to release their moisture, and that's going to start turn into all this rain, rain, rain, rain, rain, rain.

And so this side, this sort of ocean -facing side of the mountain here ends up just getting a lot of rainfall.

And so that's where we get a lot of the forest, you know, actually the other side of the mountain is going to stay relatively barren...
