OK, I need to define density and give 3 examples of its definition...(example--ice is less dense then liquid water, so ice floats on the water. Thats only an example, I cant use it.
 
your head is more dense than air, so it doesnt float away, unlike helium, which when filled into the more dense balloon to capture and contain it, does float away?



 
Seriously, did this homework really warrant an all caps title and three exclamation points? Look up density in a dictionary. And I'm sure you can find dozens of charts that list densities of various materials to get your examples.
 
bowling balls are more dense than milk, so they sink

I told you, go to Dictionary.com - they have an encyclopedia/thesaurus linked from there, you can find your definition there.
 
OK, I have another question. How can I relate convection and density to the structure of the earth, to explain the driving mechanism of plater tectonics.
 
Simply put, density is mass per unit volume.

Re: Plates and stuff-

I would show you my skills of an artist, but in a post here I cannot. Besides I am too lazy. The rock that floats above the mantle is less dense. Else it would sink. Now heat from the earths core is brought to and travels through the mantle via convection. Convection is really the circulation of heated material. The convection currents move to the topmost layer of the mantle, and as they do, the crust moves too. Simple. You see this if you put something that floats in water, and then heat it. As it moves, so does the floating object.
