Plate Tectonics

A Path To Victory!

Page 2: Plate Tectonics

1. What is happening here?

Page 3: Plate Tectonics

Answer 1

Divergent boundary, 2 oceanic plates, mid-ocean ridge forming!

Page 5: Plate Tectonics

Answer 2

• Folded mountains form when 2 continental plates converge—collide.

Page 8: Plate Tectonics

4. What is happening here?

Page 9: Plate Tectonics

Answer 4

• Rift valley forms when continental plates diverge.

Page 10: Plate Tectonics

5. What causes this?

Page 11: Plate Tectonics

Answer 5

Subduction: When heavier plate dives beneath less dense plate.

Page 12: Plate Tectonics

6. What types of plate subduct?

Page 13: Plate Tectonics

Answer 6

• Oceanic plates subduct beneath continental plates or other oceanic (less dense) plates.

Page 14: Plate Tectonics

7. What crustal features form at subduction zones?

Page 15: Plate Tectonics

Answer 7

• Trench, volcanic mountain

Page 16: Plate Tectonics

8. What is forming here?

Page 17: Plate Tectonics

Answer 8

• Mid-ocean ridge volcano!

Page 18: Plate Tectonics

9. What type of boundary is this?

Page 19: Plate Tectonics

Answer 9

• Divergent: 2 oceanic plates pulling apart.

Page 20: Plate Tectonics

10. Where do trenches form?

• ??????

Page 21: Plate Tectonics

Answer 10

• At subduction zones.

Page 22: Plate Tectonics

11. What are 2 ways volcanoes can form?

Page 23: Plate Tectonics

Answer 11

• Mid-ocean ridge Subduction

Page 24: Plate Tectonics

12. What powers plate tectonics?

?????

Page 25: Plate Tectonics

Answer 12

• Convection in the mantle!

Page 26: Plate Tectonics

13. Name 3 supports for continental drift

Page 27: Plate Tectonics

Answer 13

Page 28: Plate Tectonics

14. How does subduction form volcanoes?

• ???????

Page 29: Plate Tectonics

Answer 14.

• Subducting plate melts then “bubbles up” to form volcano.

Page 30: Plate Tectonics

15. How did these possibly form?

Page 31: Plate Tectonics

Answer 15

• Aleutian Islands

Page 32: Plate Tectonics

16. How did this form?

Page 33: Plate Tectonics

Answer 16.

• Two oceanic plates diverging-mid ocean ridge.

Page 34: Plate Tectonics

17. What do you think this is?

Page 35: Plate Tectonics

Answer 17.

• Iceland! Part of mid-ocean ridge (Atlantic)

Page 36: Plate Tectonics

18. What is this?

Page 37: Plate Tectonics

Answer 18

• Ring of fire! Subduction zones around the world form this ring.

Page 39: Plate Tectonics

Answer 19.

They get older…they move closer to subduction/trench.

Page 41: Plate Tectonics

Answer 20.

• Rocks formed at ridge record earth’s magnetic field reversal.

Page 42: Plate Tectonics

21. What will most likely form at boundary of Antarctic plate and Cocos plate?

Page 43: Plate Tectonics

Answer 21.

It’s 2 oceanics diverging, so mid-ocean ridge.

Page 44: Plate Tectonics

22. What is causing the Himalayas to form?

Page 45: Plate Tectonics

Answer 22.

2 continental plates converging.

Page 46: Plate Tectonics

23. Where is oceanic crust destroyed?

??????

Page 47: Plate Tectonics

Answer 23

• Subduction zones!

Page 48: Plate Tectonics

24. Upwelling here shows what forming?

Page 49: Plate Tectonics

Answer 24.

• New ocean floor/rock

Page 50: Plate Tectonics

25. Where in the U.S. would we find a transform boudary?

• ?????

Page 51: Plate Tectonics

Answer 25

• San Andreas fault in California
