C. Developing and Deepening Understanding 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. 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.
C. Developing and Deepening Understanding 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.
C. Developing and Deepening Understanding Normal Faults Hanging Wall The block above the fault plane, moving downward. Footwall The block below the fault plane, moving upward.
C. Developing and Deepening Understanding Reverse (Thrust) Faults Hanging Wall The block above the fault plane, moving upward. Footwall The block below the fault plane, moving downward.
C. Developing and Deepening Understanding Strike-Slip Faults 1 Right-Lateral Blocks move horizontally past each other, with the opposite side moving to the right. 2 Left-Lateral Blocks move horizontally past each other, with the opposite side moving to the left.
C. Developing and Deepening Understanding Seismic Activities and Location 1 Plate Boundaries Most earthquakes occur along plate boundaries, where tectonic plates interact. 2 Fault Zones Within these boundaries, fault zones are areas of weakness where rocks fracture and slip, leading to earthquakes. 3 Seismic Risk Countries located on or near active fault zones face a higher risk of earthquakes.
Key Takeaways 1 Fault Classification Faults are classified by their angle and slip direction, impacting seismic activity. 2 Pacific Ring of Fire This area is prone to volcanic activity and earthquakes due to tectonic plate interactions. 3 Seismic Risk Understanding fault types and their location helps assess seismic risk and prepare for potential earthquakes.
