Earth is a pretty interesting place when you think about it, and this article lists some interesting things you probably didn't know about our blue and green marble in the sky. It's one of those articles that makes science interesting (although, in my opinion, it's almost always interesting...).
Here's a teaser: the ten things, sans explanation.
1. The Earth is smoother than a billiard ball.
2. The Earth is an oblate spheroid.
3. The Earth isn’t an oblate spheroid.
4. The Earth is not exactly aligned with its geoid.
5. Jumping into hole through the Earth is like orbiting it.
6. The Earth’s interior is hot due to impacts, shrinkage, sinkage, and radioactive decay.
7. The Earth has at least five natural moons. But not really.
8. The Earth is getting more massive.
9. Mt. Everest isn’t the biggest mountain.
10. Destroying the Earth is hard.

Sandy, that's the point! Interesting stuff, huh?
Sifu, and if you take the time to read the article I linked to, you would understand why those two contradict each other...

I appreciate your good effort to make this earth look greens, but base on what my knowledge when I study in Russia, they tell that Earth green campaign is just the tools from the Capitalist Country to prevent the development of third world country.
What your opinion? Is it true?
Just want to know.

Number 9: Mt. Everest isn’t the biggest mountain.
Mauna Kea is. Plus, Mauna Kea has telescopes on top of it, so that makes it cooler.

LOL! That's pretty funny.
The one about the Earth being hard to destroy reminds me of a George Carlin bit when he says that the planet will still be here when we are gone. That it will "shake us off like fleas" when it is done with us. I thought this was pretty interesting, I always remembered what he said.
Pretty cool tidbits, thanks for sharing.

Best YouTube, the green campaign has nothing to do with preventing development of third world countries. If anything, it could help... consider solar power, for example, which can bring electricity to countries to far removed or poor for standard power.
Chip, let's hope that he was right about the planet still being here. I think it will, but will need to do a lot of healing once we are gone.

WoW, Stefanie. I really love this cool trivia about the Earth thing!
Hmm..., the "Cruithne" is a very cool concept, and I was thought it would be better if it was included as one of the moons for the Earth.

Wilson, it really shouldn't be called a moon of Earth, since it doesn't revolve around Earth, but around the sun.
