You know what time it is. It's time for Ask a Space Man. I'm your host, Paul Sutter. You've got questions and I've got answers. You know how the show works, but sometimes you could use a little bit of a

reminder. So here we go. You go online to Twitter or Facebook, use the hashtag Ask a Spaceman,

and fire some questions my way, and I'll pick ones out to answer on this show. Exhibit A is

the question I'm going to answer on today's show. So there you go,

evidence that this process actually happens. You can also send questions to my email at

Ask a Spaceman at gmail.com. You can also send me questions directly on Twitter and Facebook.

My name there is Paul Matt Sutter, P-A-U-L-M-A-D-T-T-T-E-R.

That's my name, and so it's my Facebook and Twitter handle because that's kind of how things work.

You can also go to Ask aSpaceman.com. There you'll find show notes, a place to comment. You can put questions there.

It's going to take a while, but we'll get there.

And on that road, we have today's questions, actually two questions that are kind of sort of related.

We have Mike Sarence from email and D.D. Fairchild on Twitter

asking how do planets get their magnetic fields and how do plate tectonics happen? Just how does that all

work? Well, and the first question you might ask is why in the

world am I combining these two topics? I mean, magnetic fields last time I checked are a little bit

different than plate tectonics. So what's the connection? You'll see. Don't worry. I'm going to start with magnetic fields and then we'll work our way into plague tectonics. And at the end of it, you'll have this amazing, aha, moment where you'll see how they're all connected. And it's all, it's all the same. Yes. That's important. So, and I know what you're thinking. Well, I don't know what you're
