Forum:Costs for Rock Bombardement?

I am wondering about this issue for some time now. Is the part "Send 1 Rock-Type monster from your Deck to the Graveyard" of the effect of Rock Bombardement a cost for activating this card and therefor inflicting effect damage or is it just 1 of 2 separate effects of this card? So if I wouldn't have (any more) rock-type monsters in my deck when activating this card, would I still do damage or would it just resolve without use? Or in the special case with Macro Cosmos active on the field, would I be able to activate Rock Bombardement and put the ROCK simply out of play instead of into my graveyard or would I just not be able to activate it?
