Yes, it was a bit of a stretch.This is what my son would classify as "dad jokes", earning a groan and a roll of the eyeballs.

Does the reporting system include dad jokes?You're Gondawana revise your ideas about continental drift.
I appreciate you sorting this all out with me. You're a patient man, exchemist. lolNot at all. This is just one of many geophysical tectonic processes going on all the time in an endless cycle. Don't worry about the crust being "lost". As a matter of fact, over geological time the amount of continental crust on the Earth's surface seems to have increased, due to the fractionation process that occurs when lower melting point, less dense mineral fractions are ejected onto the surface by volcanism.
In fact, now you make me read this again more closely, the journos have indeed got it wrong. They speak of the "crust" dripping into the mantle but that is not what is happening. As my earlier post pointed out, the lithosphere consists of crust on top and also a layer of cooled, rigid mantle material beneath. It is that mantle layer which is denser than the underlying, plastic asthenosphere and it is just that layer that "drips" down into it. In doing so it tends to pull on the crust supporting it, causing a depression.
The journos have made the same error I did before, with that other article I posted, of equating lithosphere with crust, when lithosphere has 2 components: crust and a denser rigid mantle layer.
Relax, wegs, it's all fine.![]()
Only with good-natured rational people, esp. those willing to learn or to teach. You will be well aware I can also be an irascible old curmudgeon.I appreciate you sorting this all out with me. You're a patient man, exchemist. lol
Aaargh!You're Gondawana revise your ideas about continental drift.
Is that what you meant to say?A treacle down effect?
That or "a treacle clown affect"Is that what you meant to say?
Hmm, sounds like ballocks….and, surprise, surprise………
Killed by bat guano. Take note if you grow your own.
At least this one looks less like a gas-powered dildo. My son and I named the first one Bellend One.Finally lift off!
