The students will be able to identify and discuss the main characteristics of the three types of plate boundaries and how they affect the formation of the earth’s surface.
Common Core State Standards:
RI. 5.2. Determine two or more main ideas of a text and explain how they are supported by key details; summarize the text.
W.5. 8. Recall information from experiences or gather information from provided sources to answer a question.
Next Generation Science Standards:
MS-ESS2-2. Construct an explanation based on evidence for how geo science processes have changed Earth’s surface at varying time and spatial scales.
Students will complete the information listed on the website (video, article, quiz) and then construct their own plate boundaries out of any materials they find in or outside of the classroom. Students will present their plate boundaries and discuss why they used the materials they chose.
In order to gain comprehension of the stated objective, please complete the following tasks:
1) Review Class Notes on plate tectonics (print out/take notes for reference)
2) View "Plate Tectonics Rap" - YouTube Video
3) View "Bill Nye the Science Guy: Plate Tectonics" - YouTube Video
4) Take the quiz! (It is about all of the information that you have read about/ watched on this page)
*you will be creating your own plate tectonics project in class.
At convergent boundaries, tectonic plates collide with each other. The events that occur at these boundaries are linked to the types of plates — oceanic or continental — that are interacting.
Subduction Zones and Volcanoes
At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone. As the oceanic crust sinks, a deep oceanic trench, or valley, is formed at the edge of the continent. The crust continues to be forced deeper into the earth, where high heat and pressure cause trapped water and other gasses to be released from it. This, in turn, makes the base of the crust melt, forming magma.
