Bell ringer (Tuesday:12/1/09) Explain the movement of a divergent boundary and describe the geological features that results Des cribe the geological features that results when divergent plates move away from each other. Describe the geological features found at divergent boundaries.

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 SWBAT compare the geological features found at divergent boundary and convergent boundary.

Convergent boundaries Description: when tectonic plates moves towards each other What is another term for tectonic plates? 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 When continental crust moves toward one another Crust crumple together and rise 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) http://www.youtube.com/watch?v=Tzt_EBD3DDQ&feature=related were formed when the Indian subcontinent collide into Asia 45 million years ago. Objective: SWBAT describe the geological features found at convergent boundaries

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

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
