Atmospheric particles? No
The earth's mantle *the audience pull shawls round their shoulders, button up cardigans and tighten scarves* No

Let's see what this volatile lot will do with this one.

A tectonic plate? *a low approving approving murmur rises from the audience* No
Molten lava? *the audience passes around Damart catalogues as the ushers attempt to turn up the radiators* No
Mineral-laden hot springs *"We could use some of those here", think the audience* No

À la Lara Croft, he muses, with a silly grin.

A continental shelf? *the audience muses on the fact that there are about 21,500 Google hits for "Lara Croft" and "the answer"* No
Magma? No
Tsunami? *the audience seeks diversion in a spirited discussion of the correct plural of 'tsunami'* No
An earthquake? No
A glacier? No
An iceberg *the audience nods knowingly at the ironic appropriateness of Chalky and irach's moves*

Looking back, I may have mis-directed people with the answer to the solid question. Perhaps a better answer would be "Yes, partly."
Do we want a clue?

Antarctica? *the audience sits up straight, puts away their papers, Sudoku puzzles and knitting* No, but in some ways the closest answer yet

[irach] that's TWO guesses - very naughty!

[Chalky] Nothing wrong with irach's question -- it has a yes-or-no answer, and if the answer were yes, then it would simply be all fingers on the buzzers to guess which one!
Oh, and if I am right, I hereby transfer my win to irach.

The ocean? No
The North or South Pole? *the audience giggle quietly* No
The Arctic Ocean? No

I'm with CdM on irach's question - people do bend the one-question rule (me included), and a single question can anyway turn into a mutiple answer (see "terrestial object" above).

Chalky has now got the geographically closest answer, but in other, more important ways, irach is still closest.

I am going away this afternoon, and work means I'm unlikely to be able to play more than once again before I go. Any volunteers to take over as quizmaster/mistress? Email me at pubsalesatbaafdotorgdotuk .

No e-mails, so...for your safety and convenience, this game will not contain any further replies from me until Monday (maybe) or Tuesday (more likely. Have a good weekend, everyone

Parting thought - the speed of this game is somehow appropriate.

Parting clue - there's a coincidental connection with both Bob Dylan and organised religion.

Well, of course a b&b in St Austell will have a broadband connection - silly of me to assume otherwise

Glacier? No
The North magnetic pole? *the audience breaks into small groups to find any connection between Bob Dylan, organised religion and the north pole, magnetic or otherwise, but fails to reach any conclusions, rejecting the theory of the small group arguing for a metaphysical interpretation of "Quinn the mighty Eskimo".* No

The Greenland icecap? *the audience wonders if their earlier tumultuous reaction to one of Rosie's moves has perhaps been overlooked* No. Direct relationship to air movement? Hmm...perhaps Rosie can shed more light on that once the answer's been revealed. Locally, yes, almost certainly; more generally, don't know.

Drifts? (snow or continental?) Either way, no.

Aurora australis? No.
A volcano? *considerable applause* No.

fergawdssakeRosie - guess the damn thing!
