Mantle convection Puns

I am a high school earth science teacher and I am conflicted on telling students WHERE in the mantle the convection occurs. In college I’m not sure if I got a consensus from professors about how the mantle works. I’ve heard that the material reaches all the way down to the outer core, or the D” layer or whatever. I’ve also heard that convection ONLY occurs in the asthenosphere/ upper mantle, and that the lower mantle is essentially static because of pressure, but it would also be hotter there, and is ALSO apparently the area that mantle plumes form in… I realize this is a hotly debated topic that goes into the slab push or pull debate on drivers of plate tectonics, but I’m not a researcher. Is it possible that there is convective cells in the asthenosphere with a base at the mesosphere, and that the mesosphere has its own convection cells?

Is there a consensus or should I just tell kids that we really don’t know yet? Thanks for discussing!

Also if you have cool diagrams that show seismic data well that would be appreciated!

Does anyone know of any good resources (books, journal articles) that describe what convection in the mantle looks like? I am looking for something detailed but not overly complex that discusses lithosphere/mantle decoupling, and single layer vs double layer mantle convection. I understand this may be difficult to find. Any suggestions are greatly appreciated. Thanks.

In other words, the Pros would be that there would no longer be natural disasters. But what are the worst Cons?

Does the Coriolis Effect affect the Earth's inner material the same way it affects the atmosphere? I would think because the mantle is fluid (well, relatively speaking), it should be pushed into the same pattern as the atmosphere, with subterranean jet streams, etc. However, if I look at a tectonic plate map, I don't see them moving as if these predictable currents are pushing them.

I know the mantle is generally solid all the way down, and that the mantle has convection, but how? I get that you can have "viscoelastic" materials like putty that deform somewhat easily but I'm struggling to imagine olivine doing this. Do the crystals move, and how? And how does this explain mantle plumes?

I am confused--intuitively, it feels like higher conductivity would cool the core faster, and so we'd get an older inner core.

But in the literature a higher conductivity is always given as a reason for a younger core (it's never really explained).

Can anyone explain what's actually going on? What am I missing here? Thanks!

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Do your worst!

I'm surprised it hasn't decade.

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂

It really does, I swear!
