Lesson 3- Earthquakes
What is an earthquake?
A sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.
What causes an earthquake?
The earth's crust is cracked into pieces called tectonic plates. These plates move around. In some places they move apart form each other and in other places, they move together. These movements are felt on the surface and they vary in size. Most are too small to be felt by humans and are measured using a sensitive machine called a seismometer. Some earthquakes are large and can cause extensive damage to property and loss of life.

2. Research the Tohoku earthquake and complete the worksheet in your packs.
3.Complete the map worksheet in your packs. In this activity, you will look at locating well known earthquakes on a world map using their latitude and longitude co-ordinates. There are eighteen earthquakes taken from history to locate and it is a good way of learning about longitude and latitude whilst also learning about earthquakes.
Use the video below to help you plot the earthquakes.
