Location and Causes of Earthquakes
Title: Location and Causes of Earthquakes
Date: 21/07/2015
Lesson Aims:
To find out the location of earthquakes around
the world.
To find out what causes earthquakes to occur.
Lesson starter:
Location of the worlds earthquakes.
On the next slide you will see a map of the world.
Discuss with each other where you think you get
earthquake activity and where you get no
earthquakes.
Be ready to come up to the board and mark on
your answers.

This map shows the plate boundaries of the Earth.
All earthquake and volcanic eruptions happen along
these boundaries.
What causes earthquakes?
The different sections of plates are constantly
moving due to convection caused by the heat of
the Earth’s core.
When the plate move they cause earthquakes,
volcanic eruptions and tsunamis.
When the plates collide massive amounts of
pressure build up. When the strain becomes too
much the pressure is released and this causes
the Earth to shake.
