The Appalachians range from Alabama up through Maine and the Atlantic Ocean; this is possible because the mountain range had been formed before the ocean was created B.

a. This is like a pair of pants with a drawstring; the strings are the ocean crust while the bunches of cloth from the pulling represent the continents; a modern example of this is India and Asia b. Continental crust will deform on the surface because it is not as dense as the oceanic crust therefore the continental crust cannot be subducted C. Biological diversity 1. Plants are very diverse: azaleas, rhododendrons, mountain laurel, and wild flowers including wild orchids 2. The abundance of rhododendrons represents how acidic the soil in the Smokies is

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
