Geo lab The Lithosphere and Plate Tectonics – 5 important facts no one talks about
Part AYour y-axis values should be in reverse with 0 m (sea level) at the top and 5500 m (or greater) at the bottom.Include another y-axis on the right-end of the cross section.
There is no x-axis label and values for the cross-section.The legend should only contain the vertical exaggeration, everything else would be labelled on the cross section.
For 2e and 2f, you should also use arrows to indicate the directions of spreading/convection.For your VE, make sure you state what your HS and VS are before calculating the plate tectonics exaggeration.In question 3, there is a typo in the manual. At the end of the sentence it should say (question 2e NOT b).
Part BRefer to map 7.2, the powerpoint on eClass and your textbook to answer question 1-7.For question 6, you would write a sentence or 2 to summarize what was written in question
5. For example: what are active margins are mainly associated to and what subduction zones are mainly associated to.For question 7,
write a process (try to be specific about the type if it’s plate tectonics volcanism or earthquake) associated with that zone and then write at least 1 type of landform associated with the process.
Part CUse the amendments (table and graph) provided to you on eClass not in the manual!Make sure to have three categories for your earthquakes (Minor, Great, and Mega)
– use different colors and/or symbols.For question 2, you may or may not see a clear pattern; if not then describe what you see in general (ex: what type of earthquakes are mainly at the surface).
For question 3, I highly suggest looking at map 7.2 to see what processes and plates are associated with Chile. I highly suggest doing the cross-section and graph in Part C by hand
