I believe it's a shame that the drippings do not create the basis of a mantle-stalagmite. That would be a neat feature to study.

'Our continent keeps on dripping, dripping, dripping, into the mantle...'

Doo-doo dah doo-doo.

Is there currently any type of ground penetrating radar or other device which could physically confirm the model's output?

it usually starts with a stalactite, then a stalagmite; by the way is there a mnemonic for the two words in English? something like t for tumbling and m for mounting...

Stalactites hold “tight” to the ceiling.

The one I've heard is 'just remember ants in pants: the mites go up, the tites come down'

I memorized it as "c" for "ceiling" and "g" for "ground."

I always remember it with “g” for ground and “c” for ceiling… haha but I do like the mites and tites one too in a neighbor comment :)

hope it holds tight...

I also heard this lame one: stalagmites might hang, but they don't.

If I needed a mnemonic today, just remember that drops slowly drip from stalactites, like drops in a chemical titration procedure.

Tights go down and mites go up.
