Learn: Natural Hazards

Welcome!Today we'll learn about natural hazards. These are physical events like earthquakes, storms, and floods that can cause harm to people and the environment. Let’s explore what they are, why they happen, and how they're managed.

What are Natural Hazards?Natural hazards are extreme physical events caused by natural processes, such as tectonic movements or weather. They can cause damage to property, disrupt lives, and harm ecosystems. Factors like population density and poverty can make their impacts worse.

Factors Affecting Hazard RiskHazard risk depends on several factors. Population density increases risk because more people are exposed to danger. Poverty can make recovery harder. Human actions like deforestation or urbanisation can also worsen hazards.

Tectonic HazardsTectonic hazards occur due to movements in the Earth’s crust. Examples include earthquakes and volcanoes. These hazards are linked to plate margins, where tectonic plates meet and move.

Why Do People Live in Risky Areas?Some people choose to live near hazards because of benefits. Volcanic soil is fertile for farming, and geothermal energy can provide electricity. Also, some locations are culturally or economically important despite risks.

Reducing Tectonic Hazard RiskTectonic hazards can be managed through monitoring (tracking movements), prediction (foreseeing events), protection (building stronger structures), and planning (educating people).

Review Time!Great work! You've learned about natural hazards, tectonic processes, and hazard risk factors. Let’s review with a few questions.
