Learn: Tectonic Hazards

Welcome!Today we'll learn about Tectonic Hazards. These are natural disasters caused by movements of the Earth's plates. Let's explore how they happen and their impacts!

What are Tectonic Hazards?Tectonic Hazards are events that result from the movement of tectonic plates. These include earthquakes, volcanoes, and tsunamis. They can cause destruction to buildings, infrastructure, and lives. It's important to understand them to reduce risks.

The Earth's StructureThe Earth is made up of layers: the core, mantle, and crust. The crust is divided into tectonic plates that float on the semi-liquid mantle. Their movement causes tectonic hazards.

Plate MarginsTectonic plates interact at plate margins. There are three types: constructive (plates move apart), destructive (plates collide), and conservative (plates slide past each other). Each creates different hazards.

EarthquakesEarthquakes occur when plates suddenly shift at fault lines, releasing energy as seismic waves. The magnitude is measured using the Richter scale.

VolcanoesVolcanoes form at destructive and constructive margins. Magma rises to the surface, creating eruptions. Some volcanoes are explosive, while others are less violent.

Managing Tectonic HazardsTo reduce the impact of tectonic hazards, we use monitoring, prediction, protection, and planning. These strategies save lives and minimise damage.

Review Time!Great work! You've learned about tectonic hazards, plate margins, earthquakes, volcanoes, and how we can manage these risks. Let's test your understanding!
