Discussion: "what single item did you already know about plate tectonics" and "what new item did you learn about plate tectonics? be specfic in your posts and follow on your statement with examples. a specific example is, "i knew mt. shasta was a subduction zone volcano, but i did not know what the origin of the magma was for these types of volcanoes." then you can be specific and explain theses topics.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
