Learners explore major fault types, including normal, reverse/thrust, strike-slip, and oblique faults, along with how fault geometry relates to rock motion. The material covers measuring earthquakes using magnitude and intensity scales, examines real effects like tsunamis, and concludes with earthquake preparedness and a case study of the 2011 Tohoku event.","Exploring Earthquakes, Faults, and the Forces Shaping Our Planet\nEARTHQUAKES AND FAULTS\nLESSON FOR MIDDLE SCHOOL\nABOUT TODAY’S LESSON\n01\n03\n02\n04\nEarthquakes & Plate Tectonics\nFaults & Seismic Waves\nEffects and Preparedness\nCase Studies\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nINTRODUCTION TO EARTHQUAKES\nBrief overview of what earthquakes are and how they occur.\nEpicenter\nFocus\nFault Scrap\nDownthrown Block\nUpthrown Block\nWave Fronts\nLateral Sliding\nSpreading\nPLATE TECTONICS\nExplanation of plate tectonics and how movement along plate boundaries causes earthquakes.\nSubduction\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nLorem ipsum dolor sit amet, consectetur adipiscing elit.\nslip\ndip\nTYPES OF FAULTS\nThe constant movement of the Earth creates cracks on its surface that affect the landscape.\nA fault is a crack or fracture on the Earth's surface between two blocks of rock.
