Geology Rocks

The fascinating, awe inspiring, beer drinking world influenced by the earths oldest science. This blog is about all things geology. Landmarks, minerals, sedimentary deposition, pretty pictures, and humor all fall into this category. If you ever have questions dealing with your labs or you homeworks, ask. I will be able to find you the answer if I donâ€™t know it off the top of my head. Also, send me links and I will give you credit. geologyrocks.tumblr.com/ask

igneous-rock-lobster: Convergent plate boundaries - pretty much THE most badass of all of the plate boundaries (the word badass? - not usually my thang (the word thang, not usually my thing), particularly given in my native Australia we might me more inclined to say badarse, which frankly, is lame - but in this instance I think it is warranted). Basically, two huge chunks of the earth (fine, the lithosphere - the outermost ‘shell’ if we’re going to get technical), crash into each other - and by crash I obviously mean collide with speeds of 2-10 CENTIMETERS per YEAR. Now my sarcastic inflection might lead you to believe that I think that this speed of CONVERGENCE (if you will) is PITIFULLY slow - not so, fine readers. You see as tectonic plates converge two different things can happen - these two things depend on what BREED of tectonic plates are involved (continental or oceanic): 1. Continental COLLISION - as my capitalisation suggests, its pretty epic or 2. A process called subduction in which one plate is SUCKED underneath the other…I know right, gross. As a result of these processes shit goes down - and by shit goes down, I obviously mean generally that shit goes up - ie. mountains and volcanoes. There can be some fairly distressing side effects to all of this EPIC tectonic action for us humans (earthquakes and resulting tsunamis being most notable) - and for that reason we should all LEARN as much as we can about the POWERS THAT BE that control our Earth (obv those HANDS controlling the plates in my last photoset…right…wait..what).
