Terminal Open Application help

I'm quite new to the whole Terminal Application and learning the basics, just messing around trying to open applications using the "open -a" command, works great no problems, but here is the newbie question, when using "open -a chess" for instance it opens chess fine. But what do I do when I want to open Google Earth for example? If I type "open -a google earth" it obviously tries to find the application in /earth. What do I type to get the space in between "google" and "earth"?

Many Thanks

Couple ways:
1. Quote it
[font=Monaco,Menlo,Courier,"Courier New"]open -a "Google Earth"[/font]
2. Escape it
[font=Monaco,Menlo,Courier,"Courier New"]open -a Google\ Earth[/font]

That's the general rule for specifying a file name/path in any Unix command, by the way; it's not just open that behaves that way.

Many thanks for the help

it's the Space between Google and Earth that, in novice terms, messes up Terminal. quoting in the command gets past the space, and the \ essentially tells the system to ignore the space that is next.

keep at it.

Many thanks, much help.
