How were the Hawaiian Islands formed?
Include diagrams and an explanation.Must be completed in your exercise book
Use the following links:

By the end of the lesson:
All pupils will be able to explain what happens at 4 different plate boundaries
All pupils will take part in a carousal activity
All pupils will understand how volcanoes are formed and the different types that exist.

What are Volcanoes and how are they formed?
A volcano is an opening or vent in the earth’s surface through which molten material erupts and solidifies as lava.
Volcanic vent
What is a volcano?
Crater Volcanic bombs, ash and gases
Main vent
Parasitic cone
Magma chamber
Cross section of a volcano
Active volcano – liable to erupt e.g. Mt Etna.
Dormant (sleeping) volcano – a volcano which has not erupted for many years. For example, Mt Pinatubo erupted in 1991 after 500 years of dormancy.
Extinct volcano – a volcano which has not erupted for many thousands or millions of years e.g. Edinburgh.
However, it is often very difficult to tell whether a volcano will erupt again…El Chichon, Mexico erupted in 1982 after being dormant for approximately 1200 years!
Do all volcanoes erupt?
Around which plate do we find most volcanoes?
Where are volcanoes found?
Volcano shapes
Why do volcanoes have different shapes?
In groups you will go to each station and complete your task sheet.
Station 1: Nazca and South America
Station 2: Eurasian and North America
Station 3: Indian and Eurasian
Station 4: North America and Pacific
You will need to complete the plate tectonic sheet
and the volcanoes sheet.
You will have 10 mins at each station
At the end of the lesson you will be asked to present information about what you have learnt.

See slides below
The Hawaiian islands are a chain of volcanoes in the Pacific Ocean.
Hawaii
Look at their location on the map below. Why is this an unusual place for them to be located?
Hot spot volcanoes
In the animation above, why are the volcanoes to the left of the ‘hot spot’ extinct?
Volcanic bombs, ash, lava, gases
Magma chamber
Parasitic cone
Crater
Main vent
