Do you want to know how volcanoes erupt?

Why does a volcano erupt? 

A volcano is a mountain with a crater filled with molten lava, ash cinders and gas that erupts when the volcano is active. A volcano is very violent and it causes a lot of damage to the environment.

Volcanoes occur along the boundaries of the earth's plates, where molten lava is forced upwards with pressure from the magma pool. Some volcanoes are active and some are extinct. When a volcano is active, it means that the volcano still may erupt one day. If a volcano is extinct, it means that it will not erupt.

Sometimes after a volcanic eruption other natural disasters including floods, landslides, earthquakes and forest fires. The ash in the air affects both humans and animals. The initial eruption usually releases the pressure of the volcano, lava continues to flow several years after the eruption.

Volcanoes are very hazardous and they cause a lot of damage. After a

volcanic eruption, the whole environment is covered in ashes. Houses and buildings are broken down or burnt badly. People may be seriously injured or even die from the eruption.
