impacts that occur instantly and as a direct result of the earthquake or volcanic eruption

impacts that follow as a consequence of the earthquake or volcanic eruption in the hours, days and weeks that follow

action taken during and immediately after a hazard event that focuses on surviving the hazard and providing short-term relief

action that focuses on rebuilding after the tectonic hazard and reducing risks from future hazards

Primary and secondary effects and responses to tectonic hazards

Geography

An introduction to natural hazards

Factors affecting hazard risk

Plate tectonics theory

Global distribution of earthquakes and volcanoes

Processes at constructive/divergent plate margins

Processes at destructive/convergent plate margins

Processes at conservative plate margins

An example of effects and responses to a tectonic hazard in an HIC

An example of effects and responses to a tectonic hazard in an LIC

Reducing risks from earthquakes and volcanoes

Using GIS to visualise physical processes at different types of plate margin

This unit teaches pupils about natural and tectonic hazards, their location, causes and effects. Pupils learn about the different types of hazard before focusing on earthquakes and volcanoes. Pupils will learn about tectonic processes, hazard impacts and the options for mitigation and adaptation.

Natural and tectonic hazards

Depiction or discussion of famine, disease, natural disasters.

Depiction or discussion of violence or suffering

The long-term environmental changes after the hazard

The immediate impacts caused directly by the hazard event

The recovery actions taken by governments

What are primary effects of tectonic hazards?

Which of the following is an example of a secondary effect of a volcanic eruption?

It is caused by underwater earthquakes displacing water

The earthquake directly generates giant ocean waves

The earthquake increases ocean temperature, creating waves

It happens at the same time as the earthquake

Why is a tsunami considered a secondary effect of an earthquake?

It helps people evacuate quickly and provides resources for relief

How does preparation help reduce the impact of tectonic hazards?

What is the point inside the Earth where an earthquake starts?

Which type of plate margin causes earthquakes but not volcanoes?

Oceanic plate sinking beneath continental plate

Which scale measures earthquake magnitude?

What type of boundary created the Mid-Atlantic Ridge?
