What is a volcano?
A volcano is an opening in the Earth’s crust through which lava, volcanic ash, and gases escape. Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth’s crust.
How does it produce lava?
It is created deep beneath Earth’s surface often 100 miles or more underground, where temperatures get hot enough to melt rock. Eventually, some magma makes its way to Earth’s surface and escapes via a volcano eruption. When magma erupts onto Earth’s surface it begins to flow, scientists then call it lava.
How are volcanoes formed?
When a tectonic plate collides and goes through the process of subduction, it sets the foundation for a volcano. The overlapping of the tectonic plates causes magma to break through the crust, which is the cause of a volcanic eruption.
