Plate Tectonics
A couple of weeks ago our class did an earth movement project
Each team picked a boundary and my team got the South American boundary. Each person in a team was assigned a certain job, the jobs were:
Seismologist- study of earthquakes
Volcanologist- study of volcanoes
Geography- study of physical structure of the earth
Geochronology- study of age of sea floor
My jobs were Geochronolgy and Seismologist.
I learned that the sea floor is spreading because the newer sea floor is coming up and spreading out in all directions as it gets older.
