a long, narrow depression formed when a tectonic plate stretches and fractures at a constructive margin, causing the land to sink between parallel fault lines

a broad, gently sloping volcano formed by basaltic lava that is runny and flows easily. Eruptions tend to be effusive rather than explosive - lava flows out

a measure of the energy released by an earthquake; a higher magnitude means a stronger earthquake

Processes at constructive/divergent plate margins

Geography

The structure of the Earth

Plate tectonics theory

Global distribution of earthquakes and volcanoes

Processes at destructive/convergent plate margins

Processes at conservative plate margins

Impacts of volcanoes in a developed and an emerging country

Impacts of earthquakes in a developed and a developing country

Reducing risks from earthquakes and volcanoes

Examples of management of volcanic hazards

Examples of management of earthquake hazards

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

This unit teaches pupils about 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.

Tectonic hazards

Depiction or discussion of famine, disease, natural disasters.

Depiction or discussion of violence or suffering

a steep-sided valley formed by plates pulling apart

has gentle slopes and erupts runny, basaltic lava

measures the energy released by an earthquake
