Volcanoes are openings in the earth’s ground. Volcanoes shoot out lava which is magma but above the ground.
Volcanoes explode because of magma that can not escape out of the ground when the tectonic plates are moving. The magma builds up and makes a magma chamber. It can get to a point where too much magma gathers in the chamber and it can’t hold any more. It causes the explosion.

Primary 6 have been doing a topic on Natural Disasters, I have chosen to do it on volcanoes!
Volcanoes: when volcanoes erupt lava bursts out and can be very dangerous .The lava can have temperatures around 5000 degrees Celsius. When volcanoes erupt the lava can cool down and turn into rock. If it keeps erupting over a long time the rock expands and it will eventually turn into a mountain. If lava is beneath the ground it is called magma but if magma or lava is above the ground it is called lava.
