Volcanoes

Can you remember what’s under your feet? crust mantle outer core inner core

Eyjafjallajökull . Eyjafjallajökull is a volcano in Iceland. Watch this video of it erupting in 2010.

Tectonic Plates The Earth’s crust isn’t one solid layer. It is broken up into huge areas called tectonic plates that float on top of the mantle. This map shows where the tectonic plates are.

How can you move your plates? Use the two pieces of paper you have been given. Lay your “plates” flat onto the table. How many different ways can you move the plates around? Rubbing together Towards each other Away from each other

What have tectonic plates got to do with volcanoes? Watch the video of a helicopter flight along the rift between two tectonic plates This valley is over 9000 years old. It is getting 7mm wider every year as the plates are still moving apart. The rocky valley floor was created by cooled lava. This valley is surrounded by volcanoes that have formed as the plates move apart Photo courtesy of Rob Young (@flickr.com) - granted under creative commons licence – attribution

How are volcanoes made? The lava and ash that are erupted through the crust build up to form the classic volcano cone shape over time. This then affects the Earth's crust, so that magma can sometimes erupt through it. Pressure builds up inside the Earth. This process is happening all the time!

What’s it all called? eruption cloud vent lava conduit magma chamber

How a Volcano is Made Use the Activity Sheet you have been given to explain how a volcano is created and grows, and what its main parts are called.
