Why Do Earthquakes Happen? 🌎 | Earthquakes Explained

Why do earthquakes happen? 🌎 Earthquakes can make the ground shake in just seconds—but the process behind them begins much earlier. As tectonic plates move, stress can build up in rocks along faults until sudden movement releases stored energy as seismic waves. In this whiteboard-style Earth Science and Geography lesson, we'll break down exactly how earthquakes happen and how scientists study them. 🌍 In this video, you'll learn: 🔹 What causes an earthquake 🔹 How tectonic plates create stress and strain 🔹 What happens when a fault suddenly slips 🔹 The difference between the focus and epicenter 🔹 How P waves, S waves and surface waves work 🔹 Why earthquakes occur along plate boundaries 🔹 Why some earthquakes happen deep underground 🔹 Magnitude vs. intensity explained 🔹 What aftershocks are 🔹 How seismometers detect earthquakes 🔹 How scientists locate and study earthquake sources The key process is: PLATE MOTION → STRESS → STRAIN → FAULT SLIP → SEISMIC WAVES → GROUND SHAKING This lesson is designed for students and curious learners interested in Geography, Geology, Earth Science, Physical Geography and Plate Tectonics. 🌎 Don't just memorize where earthquakes occur—understand why they happen. #Earthquakes #EarthScience #Geography
