Any point on earth can be located by using GPS, short for Global Positioning System. There are basically four components involved; Three sattelites and one reciever, the device many of us call the "GPS" (where it is actually a term to describe the whole positioning system). The three sattelites communicate with the reciever. They measure distances to it by sending electro-magnetic waves, which the reciever sends back and the sattelites times. Then, the sattelite can calculate the physical distance from the sattelite to the reciever onboard, and send back the result along with the exact position of the sattelite, which is known by the same technique measuring from ground stations. If 3 different sattelites do this, the reciever can make a very educated guess what the Longitude, Latitude, and Altitude is on the surface of the earth. It has a 66 foot (20 meter) presicion.

What are two ways that every place on the earth can be located?
Every place on Earth can be located using latitude and longitude coordinates, which pinpoint a specific location on the globe. Another way is through addresses, which provide a unique identifier for a particular place based on a specific street, city, and country.
How many ways is the earth rotating?
In two ways. If you could observe it from outside the solar system you would see that it rotates on its own axis every day. Second is something known as Earth's precession, in which the orientation of Earth's axis moves in a circular fashion, completing one cycle every 26,000 years. Earth also orbits the sun, but that is not a matter of Earth rotating.
