2. Quarter 1 Week 3 Most Essential Learning Competency: Describe and relate the distribution of active volcanoes, earthquake epicenters , and major mountain belts to Plate Tectonic Theory. (S10ES – Ia-j-36.1)

3. Quarter 1 Week 3 At the end of the session, you will be able to: describe the distribution of active volcanoes, earthquake epicenters and major mountain belts and infer the relationship of tectonic plates, earthquake epicenters and active volcanoes; relate the distribution of active volcanoes, earthquake epicenters, and major mountain belts to Plate Tectonic Theory.

4. PRE-TEST Directions: Read the questions carefully. Write the letter of the correct answer on your answer sheet.

5. PRE-TEST _____1. Which is true about plate tectonics theory? lithospheric plates move oceanic crust "slides over" continental crust continental crust "plows through" oceanic crust tectonic forces cause the most damage in the center of the plates A

6. PRE-TEST _____2. In what place do tectonic plates interact? centers regions reversals boundaries D

7. PRE-TEST _____3. Which is NOT the main principle of plate tectonics? Plate movements cause continents to drift Tectonic plates move relative to one another Movement of tectonic plates can be prevented Interactions of plate tectonics cause earthquake, volcanoes and mountain belts C

8. LOOKING BACK Directions: Number the following phrases according to the correct sequence to reveal the sentence that gives an idea on earthquake epicenter. Write your answer on the answer sheet.

10. Plate Tectonic Theory The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. https://en.wikipedia.org/wiki/Plate_tectonics#/media/File:Plates_tect2_en.svg

12. Basic Plate Tectonic Concepts Earth’s crust and the uppermost layer of the mantle are composed of rigid units called plates . The movement of these plates is small, in the order of millimeters per year . Large-scale geological activities occur on or near plate boundaries . Areas farther from plate boundaries are less prone to earthquakes .

13. Basic Plate Tectonic Concepts The Philippine Sea plate , which is oceanic, moves northwestward, ranging from as fast as 102 mm/year down around 54 mm/year . Most of the Philippine islands don’t lie on top of the Philippine Sea plate but on the Sunda Plate . https://en.wikipedia.org/wiki/Philippine_Sea_Plate#/media/File:PhilippinePlate.png

14. Major Key Concepts The volcanoes, earthquake’s epicenter, and major mountain belts are distributed in close proximity of the borders of the tectonic plates. Once tectonic plates moved in any possible motion, it could create changes leading to geologic features and events.

15. Major Key Concepts Most of the active volcanoes nowadays are found in the so called “ Pacific Ring of Fire ” which is practically the border of the Pacific Tectonic Plate.

16. Pacific Ring of Fire • Argentina • Belize • Bolivia • Brazil • Brunei • Canada • Colombia • Chile • Costa Rica • Ecuador • East Timor • El Salvador • Micronesia • Fiji • Guatemala • Honduras • Indonesia • Japan • Kiribati • Malaysia • Mexico • New Zealand • Nicaragua • Palau • Papua New Guinea • Panama • Peru • Philippines • Russia • Samoa • Singapore • Solomon Islands • Tonga • Tuvalu • United States https://www.quora.com/What-countries-are-in-the-Pacific-Ring-of-Fire

17. Major Key Concepts The earthquake epicenters are not found only in a specific place, but they are found everywhere where there's a border between two or more tectonic plates. It doesn't matter if they collide, move away from each other, or subduct, the earthquakes will be there.

18. Major Key Concepts The major mountain belts are found in places where tectonic plates of the same density collide, so instead some of them go and be subducted, they push against each other and lift the area up.

19. ACTIVITY 1 - Know your Boundaries Objective: Describe the distribution of active volcanoes, earthquake epicenters and major mountain belts and infer the relationship of tectonic plates, earthquake epicenters and active volcanoes.

20. ACTIVITY 1 - Know your Boundaries Directions: Study the map and answer the questions given below. Write your answer on the answer sheet.

21. ACTIVITY 1 - Know your Boundaries Critical Thinking Questions: (1) How are earthquakes distributed as shown on the map? Earthquakes are randomly distributed over the Earth’s surface. Earthquakes are not randomly distributed over the Earth’s surface.

22. (1) How are earthquakes distributed as shown on the map? Earthquakes are not randomly distributed over the Earth’s surface.

23. Critical Thinking Questions: (2) Where are the earthquakes located on the map? Some are located near the edges of the continents. Some are in mid-continents while others are in oceans.

24. (2) Where are the earthquakes located on the map? Some are located near the edges of the continents. Some are in mid-continents while others are in oceans.

25. Critical Thinking Questions: (3) How are volcanoes distributed on the map? Volcanoes are randomly distributed. Volcanoes are not randomly distributed.

26. (3) How are volcanoes distributed on the map? Volcanoes are not randomly distributed.

27. Critical Thinking Questions: (4) Where are the volcanoes located on the map? Majority of the volcanoes are found along the edges of some continents. Most of the volcanoes are located in western coast of North and South America, East and Southeast Asia.

28. (4) Where are the volcanoes located on the map? Majority of the volcanoes are found along the edges of some continents. Most of the volcanoes are located in western coast of North and South America, East and Southeast Asia.

29. Critical Thinking Questions: (5) Describe how the active volcanoes, earthquake epicenters and mountain belts are being distributed in the Earth’s lithosphere. They are distributed in close proximity of the borders of the tectonic plates. They are distributed far apart from the borders of the tectonic plates.

30. (5) Describe how the active volcanoes, earthquake epicenters and mountain belts are being distributed in the Earth’s lithosphere. They are distributed in close proximity of the borders of the tectonic plates.

31. POST TEST Directions: Write TRUE if the statement is correct; FALSE if it is not. Write the answer on your answer sheet.

32. POST TEST ___________1) The distribution of the volcanoes, earthquake epicenters, and major mountain belts are distributed in close along the borders of the tectonic plates. T

33. POST TEST ___________2) The theory of plate tectonics states that since from the very start, plates are already separated and has volcanoes and mountain ranges on it even without plate motion. F

34. POST TEST ___________3) Earthquake epicenters are found everywhere where there is a border between two or more tectonic plates. F

35. POST TEST ___________4) Volcanoes and earthquake epicenters are located far from plate boundaries. F ___________5) Plate tectonics suggests that Earth’s crust is made of plates that interact in various ways, thus producing earthquakes, mountains, volcanoes, and other geologic features. T
