h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Nice entry. A couple of inaccuracies that should be pointed out though.
First "water in rocks could explode", this is a possibility, but an unlikely one. It is far more likely that quick heating of the outer layer of rock will cause stresses in the stone which may lead to cracks. Under the right conditions these can form explosively and fling shards of rock outwards. This principle was used in mining, but to get a sufficiently quick change in temperature they did it the other way round, throwing water on rocks heated by fire.

"rather than wood lying on the floor. Wood from the ground" This looks wrong to me, but then I'm a foreigner so... I know you can talk about the forest floor, but...

Also, in a life and death situation other fires might be better, depending on the available wood.

Rather than 'wood lying on the floor', I too think 'ground' might be better. The next sentence could begin; 'The latter can...', rather than 'Wood from the ground can...'.

I agree that ground would read better. I'll ask if it can be changed.
