14.A Develop and use a model to show the tectonic process of uplift can create mountains at a time scale too large to see.

Look for students to show an ancient ocean between the Indian and Eurasian plate. Students should model the tectonic plate movement of the Indian plate from the Southern region of a world map to the Northern region over millions of years. Look for students to show that during this process, the oceanic plate material is broken up and some of that material is pushed up during the collision of the Indian plate and Eurasia over a scale that spans millions of years. This slow process of plate material folding should be modeled and explained, condensing millions of years into three distinct models. See Key for the Fossil Assessment for further guidance.

• Revisit the puzzle pieces from Lesson 11 and consider the placement of the Indian and Eurasian plates. Determine what had to occur over time for the two plates to have merged together.
• Look back at data (specifically coral reef data) to determine that there was once an ocean between India and Eurasia.
• Discuss what must have happened to the oceanic plate material that used to exist between the two plates based upon the plate movement arrows on the basemap and GPS data, and what life would have once existed in that space.
• Revisit the slow plate folding processes from Lessons 6-9 to determine what occurred when the two plates collided to create the mountains we now see today.
