2. Cooperate with others. C Always be respectful A Raise your hand to speak R Engage in learning E

3. OBJECTIVES: Describe the Pacific Ring of Fire. Classify the geologic faults according to the angle of the fault plane and the direction of slip. Acknowledge the relevance of seismic activities with the location of the country by answering the reflection of learning.

4. Write as many words as they can recall that are associated with the volcano. On a sheet of paper: ½ crosswise

6. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY FAULT It is a fracture in the Earth's crust through which movement has occurred.

7. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY E T R A H A U E K Q It is a sudden and violent shaking of the ground caused by the movement of the tectonic plates beneath the earth. It can occur on land or under the ocean.

8. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY EARTHQUAKE It is a sudden and violent shaking of the ground caused by the movement of the tectonic plates beneath the earth. It can occur on land or under the ocean.

9. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY H A I G N N G W L L A The side of a non-vertical fault that occurs above the fault plane.

10. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY HANGING WALL The side of a non-vertical fault that occurs above the fault plane.

11. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY F T O O L A L W The side of a non-vertical fault that can be found below the fault plane.

12. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY FOOT WALL The side of a non-vertical fault that can be found below the fault plane.

13. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY S E I I C M S A I I C T T V Y Also referred to as seismicity, is the occurrence and distribution of earthquakes in a region.

14. Direction: Unscramble the letters of the term being described by the given statement. UNLOCKING CONTENT VOCABULARY SEISMIC ACTIVITY Also referred to as seismicity, is the occurrence and distribution of earthquakes in a region.

15. Describe the Pacific Ring of Fire The Pacific Ring of Fire is an area of intense seismic activity that circles the Pacific Ocean. It's characterized by a chain of volcanoes and frequent earthquakes.

16. Describe the Pacific Ring of Fire This ring is a result of tectonic plate interactions where the Pacific Plate collides with other plates, creating subduction zones that trigger volcanic activity and earthquakes.

17. Classify Faults by Angle and Slip Fault Plane Angle The angle of the fault plane determines the type of fault : Normal , Reverse/Thrust , or Strike-Slip Direction of Slip The direction of slip along the fault plane classifies the fault further, depending on whether the blocks move up or down.

18. Normal Faults Hanging Wall The block above the fault plane, moving downward . Footwall The block below the fault plane, moving upward .

19. Reverse Faults (THRUST) Hanging Wall The block above the fault plane, moving upward . Footwall The block below the fault plane, moving downward .

20. Strike-Slip Faults Right-Lateral Blocks move horizontally past each other, with the opposite side moving to the right. Left -Lateral Blocks move horizontally past each other, with the opposite side moving to the left.

21. Seismic Activities and Location Plate Boundaries Most earthquakes occur along plate boundaries, where tectonic plates interact . Fault Zones Within these boundaries, fault zones are areas of weakness where rocks fracture and slip, leading to earthquakes . Seismic Risk Countries located on or near active fault zones face a higher risk of earthquakes .

22. WRAP- UP ! Pacific Ring of Fire This area is prone to volcanic activity and earthquakes Fault Classification Faults are classified by their angle and slip direction, impacting seismic activity . Seismic Risk Understanding fault types and their location helps assess seismic risk and prepare for potential earthquakes.
