Plate Tectonics
Earth's Interior and Plate Tectonics
Questions
1) Think of the structure of Earth's interior like that of an apple. Name the 3 main layers of Earth's interior. Explain why these distinct layers exist. You may divide the innermost layer into 2 parts, if you wish.
2) Discuss some differences between oceanic and continental crust.
3) Explain the Theory of Plate Tectonics.
4) What mechanism drives plate movement? What is the role of the mantle in plate movement?
5) What is seafloor spreading? What is a mid-ocean ridge?
6) On average, how fast are plates moving?
7) Name (and describe the relative motion of) the 3 types of plate boundaries.
8) Identify the plate boundary for each plate combination below. The possible choices are divergent, convergent, and transform.
Pacific and North American Plates (San Andreas Fault):
Nazca and South American Plates:
South American and African Plates:
9) What is a hot spot?
10) Find a short Internet video (less than 5 minutes long, if possible) that briefly explains Plate Tectonics. Please treat it professionally and choose a video that would be appropriate to show at a conference. Be sure to work independently.
