Deirdre Coffield English 090-B10 July 26‚ 2010 Earth vs. humans When the earth began it was filled with gases and molecules. Then there was water‚ plants and animals and years ago man came. Through the years humans have evolved beyond our expectations‚ while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume‚ the environment is constantly being affected. First the very stuff we breathe

earths crust. As it moved along the crust‚ friction caused the plates to move. These convection currents beneath the earths surface forced the Australian plate to collide with the Pacific plate. Along this plate boundary‚ the pacific plate was being subducted underneath the Australian plate- which held the North Island of New Zealand. This made the Australian plate near the boundary buckle and bend as it pressed up against the Pacific plate. The limestone that was formed on the seabed was then forced

the risk they pose differs around the world. One factor that heavily influences how hazardous a volcano is‚ is the plate boundary that it lies on. Subductive plate boundaries tend to produce much more violent eruptions than conservative or constructive margins. Subductive boundaries occur where two plates (one continental and one oceanic) are moving toward each other. The denser plate‚ the oceanic‚ is forced underneath the continental. As it subducts into the asthenosphere‚ it begins to turn back

The mouth-watering aroma flooded my nose as I entered a room full of patrons and food. I was mesmerized by the atmosphere of the restaurant. The sound of the music mixed with the clashing of utensils and plates‚ and the sizzling sound of food being cooked by professionals was all too familiar. It was here where my family had our very first high class dinner. As my parents were ordering from the menu‚ I was witnessing the chef preparing beef. He first placed the beef on a pan and poured

The structure of the earth The earth has three major parts-the land part or lithosphere‚ the water part or hydrosphere and the air part or atmostpere. The lithosphere is the surface on which you live . It is also the earth solid sphere consisting mainly of massive rocks. The massive rocks form large land masses called continent and small island groups . Different land form such as mountains‚hills‚valleys‚plateaus and plains make up the lithosphere. The hydrosphere include all water forms

The volcano we modeled was Erta Ale. Erta Ale is a active shield volcano. This volcano is located in Ethopia on the continent Africa. This volcano is on two divergent plates. It is the Afar rift that is causing the volcano to continue to be active today. The two plates that are responsible for this are the Nubian and the Somalian plates. Considering this is an active volcano‚ it does produce slow moving magma. The volcano doesn’t have a huge eruption it is small and builds up in the crater and causes

winds through all major ocean basin like the seams on a baseball. Ridges vary in width from 600 miles to 2500 miles. The mid-ocean ridge represents an area where‚ lithospheric plates move apart and new crust is created by magma pushing up from the mantle . Also‚ the mid-ocean ridge system is an example of a divergent plate boundary. 4.) Briefly describe the process of continental rifting. Where is it occurring today? As crust is pulled apart‚ rifts are formed and eventually become large enough
