World Around Us Lesson 1



World Around Us - Natural Disasters

I hope that you enjoyed learning about the different layers of the earth and the ‘Ring of Fire’ last week. This week you will be looking at how a volcano is formed and the different types of volcanoes that can be found on our planet.


Lesson 3 – How a volcano is formed and why they erupt 

“A volcano is formed when there is a crack or hole in the earth’s crust. This is called a vent. The temperature in the deeper layers of the earth sometimes gets so hot that it melts rocks that are deep down in the earth, in the mantle and the core. Then, extremely high pressure from inside the earth builds up so much that it forces the melted rock up out of the earth through the vent, causing a volcano!” In this lesson you will learn about the process of how volcanoes are formed and why they erupt.

Step 1 – Read slides 7 – 10 of the ‘All About Volcanoes’ PowerPoint

Step 2 – Watch the ‘What is a volcano?’ YouTube video

Step 3 – Open the ‘Volcanoes Labelling Activity’ PowerPoint. Copy the diagram of the volcano into your workbook or on a piece of paper. Label and colour in your diagram and explain each of the terms listed.

*When you open this document, the answers are also included.

Step 4 – As an extra challenge, write out the definitions for the different stages of volcanoes (active, dormant and extinct) below your diagram. Use the ‘All About Volcanoes’ PowerPoint to help you.
