Name: __________________________ Notes: Plate Tectonics 1. The Theory of __________________ explains why the ___________________ appear to drift with time. 2. _____________________ first proposed the idea of continental drift in the early 1900’s. 3. Describe the evidence for continental drift below: 4. Lithospheric plates consist of _____________ or ______________ crust “floating” on the ______________________________ 5. The force that causes the lithospheric plates to move is : ___________________ located in the _________________. 6. There are three types of plate boundaries; a) Divergent, which means____________________________________ b) ________, which means____________________________________ c) ________, which means____________________________________ 7. The Mid-Atlantic Ridge is a _______________________plate boundary, and it is ______________________ at a rate of _________ cm per year. This is called “Sea Floor __________________________” 8. Magnetic anomalies are symmetrical patterns of magnetic polarities on either side of a mid-ocean spreading ridge. They show that the rocks on the sea floor are ( older / younger ) the closer you get to the mid ocean ridge. 9. The rocks on the sea floor are ( older / younger ) the farther you get from the mid ocean ridge. 10. Below is an example of one side of the mid ocean ridge spreading center, showing the magnetic polarity of the rock units. Draw in the other side and label where the youngest rocks and oldest rocks are on each side of the ridge. 11. The Theory of Plate Tectonics states that a) ______________________________________________________ b) ______________________________________________________ c) ______________________________________________________ 12. A ________________________ plate boundary occurs when two plates slide along side each other. An example is: _________________________________ 13. A Convergent Plate Boundary occurs when two plates ____________________. The three types of convergent boundaries are: 1) _________________________________ example: ________________ 2) _________________________________ example: ________________ 3) _________________________________ example: ________________ Identify the type and label the features found at the plate boundaries shown below: Draw and label the missing type of convergent plate boundary: Examples: _________________________ __________________________________ Examples: ___________________________ ____________________________________ The Ring of Fire is ________________________________________________________ A Hot Spot is_____________________________________________________________ ________________________________________________________________________ Where do most earthquakes and volcanoes occur? ________________________________________________________________________ ________________________________________________________________________ According to the ESRT on p _____________ there are __________ types of plate boundaries. Draw and label the symbols for each type of plate boundary shown on this page of the ESRT:
