When some application, say maps.google.com, asks you to allow your location info to be transferred, the browser ALREADY know your address because it already got it from Google (via https://www.google.com/loc/json), so it's not hard to guess that Google already knows it to 
There is an easy way on how to get rid of it in FF and even fake your location (I can make maps.google.com to detect my location as White House ) but you can't do it with Chrome  |
It's not your Wifi that does that, it's the product/machine/software behind it... like the iphone has built in GPS, the location info is passed to Google Maps. While my iTouch doesn't, and Gmaps still thinks I'm in San Fran, which I haven't visited in almost a year.
For Chrome.... you have to 'allow' the extension to be installed, it's not automatic.

What everyone is suggesting in this thread would be the largest privacy violation in the world and violate 90% of the Countries privacy laws, if they even did .1% of what was suggested in this thread.
Edit: Devices with no GPS, if you walk through an area with lots of public wifi's and you try to connect, several wifi's with locations being broadcast through them, will help a non GPS device find its location. The more wifi's around you, the better it will pin point you.
