Tectonic plates are like jigsaw pieces which make up the Earths crust.
When one plate goes over another, the plate underneath melts and turns into magma. At the other end of the plate, a vent is formed. A vent is a hole in the Earth where magma and gas can escape.

As the lava escapes from the vent, a volcano is formed. As the volcano grows it will continue to erupt. The flanks of the volcano are heavier than the magma, so when the magma has nowhere to go, it goes up the conduit and erupts from the throat of the volcano!

Today in class we have found out how lava is made. We did an experiment with out own volcano to see what an eruption looks like. We used food colouring, vinegar and bicarbonate of soda.
