Transcript of What is a volcano? by Ali abdulrahman 5/6 Lyrebird

Brainstorm
"Cubing" Method
A volcano erupts because of the gas and the pressure blocking
the way for the magma to rise and if previous eruption occured before than there also must be rock blocking the way.
BRAINSTORM
ELEMENTS
copy and paste as needed to add notes to your brainstorm
Cubing is a brainstorming strategy outlined in the book, Writing, by Gregory Cowan and Elizabeth Cowan (New York: Wiley, 1980). With cubing, like with other brainstorming methods, you start with one topic, challenge or issue. Then, you apply six points of view (like the six sides of a cube) to the issue.
A volcano has a crater so the magma can come out. Main vents and side vents so the magma can squeeze through. A magma chamber so the magma is stored there. The earths crust so the lava is turned into rock.
What is a volcano?
Three stages of a volcano
There are three stages in a volcano. Active, Dormant and Extinct. An active volcano is a volcano that can erupt at any second. A dormant is a volcano that will erupt in a few years and an extinct volcano is a volcano that will never erupt again.
A volcano is a huge mountain that spills out magma or lava. It is a cone shaped mountain that can sometimes have poisonous gases in it and has ash clouds that can kill humans. A volcano has rock inside and when it is spilled out, it is called lava. A volcano has a hole so the magma can come out.
