When a dust cloud first condenses into a planet, there's a lot of heat generated from friction between dust particles, collisions with other planetoids, impacts from meteorites, and so on. So the newly-formed planet is very hot, and mostly molten. As the planetary system ages, there's less and less other material impacting on the planet, so less heat being produced that way, and the planet starts to cool. However, decaying radioactive isotopes produce a significant amount of heat as well, which dramatically slows the cooling rate of the planet. If there were no heat-producing isotopes in Earth's core, it would've cooled enough to be completely solid long ago.
So the core of a planet gets hot through friction from collisions with other objects during formation, and stays hot due to the heat produced by decaying radioactive isotopes.
Can anyone closer to their Geology 101 class or Astronomy 101 class remember how many inches the crust moves tidally?
My off-the-top-of-my-head memory is telling me that it's around 50cm (about 20 inches, or 0.006 American football fields, if I've made my calculations correctly...)
Yeah, what you said. (Isn't it always the way - as soon as you post something, someone comes along and says the same thing but in more detail and with links and references too...)
There's been a lot more than just two mass extinctions over the history of the earth - there's evidence of events where up to 90% of existing species have disappeared scattered throughout the fossil record. Some of these have probably been caused by meteorite or comet impacts, others quite possibly by large geological events - massive lava outpourings can release enough CO2 into the atmoshpere to have a definite effect on world climate.
Rallisport goes so far as to model the dirt that accumulates on the car as you race
That by itself is nothing new - the original Colin McRae Rally did that back in 1998. (Although I'm sure it looks a hell of a lot better on the X-Box...)
But, the book itself was monochrome, and its primary interface was text-- not even color text at that.
Doesn't that mean that it has to be an improvement?
Certainly not an improvement in resolution - try scanning in a page from the book and viewing it at 160x200...
its an independent review written by someone not working for a major media Web site.
Independent, yes, but if it's an impartial, unbiased viewpoint you're looking for, a site called "msboycott.com" probably isn't the best place to start looking...
Isn't time-shifting of a program considered legitimate under Fair Use?
Is there actually anything that says which direction it has to be shifted in...?
If it makes for better games and a less stressful development schedule, I think most development studios or publishers will sell a texture here and there.
I'd think if anything it'd create a more stressful development schedule. If the funding for creating the game is coming from advertising, then there's going to be a lot pressure from the advertisers to get the game out as quickly as possible, regardless of whether or not the product is as good as it can be. All they care about is getting their logo out there and in peoples faces - they're not going to want to just wait for a couple more months while the developers play around and fine-tune the game to make it perfect...

According to Snopes, that's not actually true...
Still, that particular clause could turn out to useful when trying to nail spammers who try and cover up where they're spamming from... couldn't it?
It's both.

Sorry but there no CD that I can think of that is worth $30 bucks.
Good thing you don't live in Australia then - that's the standard price here for a new-release CD...

Note that there are two different big extinctions
