which started first global warming or underwater volcanoes and opening fault lines?:(

Errrrr.
Bear in mind without some form of global warming there wouldn't be life on earth as we know it.
Also how far back are you talking.
Do you really want use to do ALL of your homework on this subject, judging by your recent posts ??

Refer to this announcement: http://www.askmehelpdesk.com/math-sciences/announcement-font-color-ff0000-u-b-read-first-expectations-homework-help-board-b-u-font.html

is not my homework
I'm just interesting in global warming , volcanoes and opening fault lines ,earth,space,sun,moon ,light year,light sun .. ets and i'm searching

You need to read this then: Global warming - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Global_warming)

The following search might also be of interest to you in your personal research then.

Some reading material related to your interest in volcanoes,global warming and fault lines.

Earth Will Survive Global Warming, But Will We? | LiveScience (http://www.livescience.com/environment/070201_gw_life.html)

Global warming and cooling has been occuring in cycles and for various reasons, and long before mankind was around. The North pole doesn't revolve like an old phonograph record stem, but slowly wobbles in an orbit of its own that causes cycles of cold and warm weather in different parts of the Earth at different points in the cycle. Catastrophic natural occurences, such as the recurring caldera explosions in Yellowstone National Park, also contribute to sharp variations in global climate.

Your literal question was however, which occured first, global warming or the two other things you mentioned. Technically, global warming occured first billions of years ago when the Earth was still forming and was constanly being struck by rocks and other materials from space to such an extend that it was largely a molten planet. As these collisions subsided, the planet cooled and formed oceans, etc.

If by global warming you mean global warming as it is presented today, namely, "a dastardly force that we humans have imposed on even the smallest of cute little bunnies for our own selfish gain, through out which we live in rich lavish oblivious comfort while Bambi sweats it out under the hot sun whose effects have been multiplied by the greenhouse effect established by gasses we produce," then the answer would be underwater volcanoes and fault lines, as todays perception of global warming has only been around since Al Gore didn't become president, some time after he invented the internet. If you mean global warming as in the natural cycle the earth goes through, hence ice ages (and the recession of ice ages), then it is hard to say. Plate tectonics and global warming, from my knowledge, have little to do with each other, and it would be my *assumption* that they both began around the same time, though we're talking billions of years here, so that could mean hundreds of thousands of years apart. However I think I remember something from geology about how the Earth when it was first created didn't have a stable atmosphere, and was pretty much all volcanoes and jagged peaks, most of which have been weathered and eroded by billions of years of elements. So if I were to guess, I would think the plate tectonic part was the first, global warming to occur later. Good luck on finding a more conclusive answer than mine!
