OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

Description
find more resources at oneclass.com Lecture 2: Plate Tectonics I. Structure of Earth: 1. Chemical - Elements: Oxygen, Silicon, Aluminum, Iron. - Crust => Two types: 1. Oceanic Crust (OC) => Elements: Fe, Mg => "Mafic". => Heavier; Higher Density. 2. Continental Crust (CC) => Elements: Si, O. => Lighter elements; Lower Density. - Mantle => Elements: 0, Mg, Si, Fe; located between the Core and the Crust. - Core => Elements: Fe, Ni. 2. Physical - Crust = Lithosphere (crust and upper mantle). => Solid layer. - Asthenosphere = (2nd layer) upper mantle; Plastic (halfway between solid and liquid layer). - Mesosphere = mantle, solid layer. - Core = has two layers => Inner Core and Outer Core. find more resources at oneclass.com find more resources at oneclass.com => Has an ability of magnetic field - protective properties. II. Basics - Lithosphere divided into plates. - Most plates have both continental and oceanic crust. => Ex: Africa, Eurasia, Antartica. - Plates in motion can trigger earthquakes and they are very deadly plates. III. Plate Tectonics A. Divergent Plate Boundary: - "Fiston Theory" - Also called as constructive boundary (new young rocks are being formed; making new rocks). - Have classic characteristics. - Ex: The Great Reef in Africa (Rift Valley). - Chemistry of rock is simila
