Bell ringer (Tuesday:12/1/09) • Explain the movement of a divergent boundary and describe the geological features that results
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
Convergent boundaries • Description: when tectonic plates moves towards each other Objective: SWBAT describe the geological features found at convergent boundaries
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
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
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
Examples of convergent boundary colliding • Himalayas Mountain (Asia) • Alps (Europe) • Appalachian (North America) Objective: SWBAT describe the geological features found at convergent boundaries
Convergent boundary of two continental plates. Forms ______________range. Examples: ___________,_____________, ______________ mountain Himalayas Alps Appalachians Objective: SWBAT describe the geological features found at convergent boundaries
Double bubble: Geological Features • Note: Similarities go in the center bubbles. Differences go in the outside bubbles. Convergent Boundary Divergent Boundary
Plate boundaries that move away from one another is? • Transform boundary • Convergent boundary • Divergent boundary
Which of the following is an example of a colliding convergent boundary • Mid- Atlantic ridge • San Andreas Fault • Himilayas Mountain • Mediterranean Mountain
Which tectonic plate collided with asia to produce the Himalayas' mountain • Nepal • Pakistan • Bangladesh • India
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
Prediction • What do you think would happen to Nepal 50 million years away from now?
