Understanding Geological Features of Convergent Boundaries

This lesson focuses on the movement and geological features associated with convergent boundaries, where tectonic plates collide. As plates compress, they form mountain ranges, such as the Himalayas, Alps, and Appalachians. We will compare these features to those at divergent boundaries and analyze how earthquakes occur in this context. Students will hypothesize about mountain formation and relate everyday experiences to geological processes. The lesson includes interactive activities, examples of convergent collision boundaries, and discussions about tectonic plate interactions.

Presentation Transcript

  1. Bell ringer (Tuesday:12/1/09) • Explain the movement of a divergent boundary and describe the geological features that results

  2. Topic: Convergent boundaries chapter 10 • Objective: • SWBAT describe the geological features found at convergent boundaries • To compare the geological features found at divergent and convergent boundaries

  3. Convergent boundaries • Description: when tectonic plates moves towards each other Objective: SWBAT describe the geological features found at convergent boundaries

  4. Based on what you just learned, hypothesize how mountains are formed? • Thinking time : 20 seconds Objective: SWBAT describe the geological features found at convergent boundaries

  5. Geological features: Convergent “collision” boundaries • Tectonic plates move towards each other & collide • The tectonic plates are compressed • Land is pushed upward forming mountains range • Shallow Earthquakes Objective: SWBAT describe the geological features found at convergent boundaries

  6. Analogy • Come up with a picture from everyday life that you can relate with convergent boundaries colliding • Example: Objective: SWBAT describe the geological features found at convergent boundaries

  7. Examples of convergent boundary colliding • Himalayas Mountain (Asia) • Alps (Europe) • Appalachian (North America) Objective: SWBAT describe the geological features found at convergent boundaries

  8. Video clip

  9. Convergent boundary of two continental plates. Forms ______________range. Examples: ___________,_____________, ______________ mountain Himalayas Alps Appalachians Objective: SWBAT describe the geological features found at convergent boundaries

  10. Questions/clarification time

  11. Double bubble: Geological Features • Note: Similarities go in the center bubbles. Differences go in the outside bubbles. Convergent Boundary Divergent Boundary

  12. CFU: questions

  13. Plate boundaries that move away from one another is? • Transform boundary • Convergent boundary • Divergent boundary

  14. Which of the following is an example of a colliding convergent boundary • Mid- Atlantic ridge • San Andreas Fault • Himilayas Mountain • Mediterranean Mountain

  15. Which tectonic plate collided with asia to produce the Himalayas' mountain • Nepal • Pakistan • Bangladesh • India

  16. Question How are convergent collision boundaries formed? • Magma rises to the surface as plates move apart, results in mid-ocean ridges. • Oceanic lithosphere subducts (or sinks) under continental lithosphere. • Two continental lithosphere collide, neither one sinks under the other. • Two layers of lithosphere slide past each other

  17. Prediction • What do you think would happen to Nepal 50 million years away from now?
