Notes to the teacher:

Learning objectives covered by this activity: (Choose which most applies to your situation).

• Investigate what is beneath our feet, (e.g. by researching the cross section of the Earth).

• Understand how each of the layers of the Earth’s cross section has unique properties.

• Explain what happens before, during and after an eruption. • Understand the key features of an eruption. • Research the global distribution of volcanoes.

Ideas to include use of ICT / Computers:

• Using secondary sources of information to research what happens in an eruption.

Ideas for extension: • Create a cartoon strip showing simple sequence of events that demonstrate how

mountains are formed. • Discuss the process of mountain formation in pairs and consider how it has shaped

land. • Design and make a model showing the inside of the Earth. • Imagine what it would be like to witness a volcano erupt.

Conflicting stories mentioned in the videos.

• Is the mantle solid or liquid? Different videos give different views but it is now thought that the Mantle is solid.

• The videos do not name the different plate boundaries in the same way. See below for some alternative names given in the videos.

Name of plate boundary Same thing, different name

Subduction plate boundary = Convergent plate boundary Compression plate boundary = Convergent plate boundary

Extension plate boundary = Divergent plate boundary Transform plate boundary = Transform plate boundary

Volcanoes Video comprehension

9 List the different types of plate boundary.
