Lessons taught to us in Grade 9 3rd Semester in FTHS.
this will contain parts of the volcano, and the kinds of volcanoes.
This is a draft cheat sheet. It is a work in progress and is not finished yet.
What are Volcanoes?
An Opening in the Earth's Crust, where as Molten Rock, Hot Gases, and other Materials Erupt |
A Vent in the Crust where Eruptions occur. |
How are Volcanoes Formed?
Magma Rises from hotspots and erupts as lava through cracks in the surface forming volcanoes. |
Cone
is the most striking part of the volcano |
it is usually composed of mixtures of lava and pyroclastic materials |
volcano cones vary in size and shape depending on the type of magma that is ejected by a particular volcano |
for instance viscous and slow moving granatic magma creates low to almost flat cones |
a Volcanic Cone is the Hill-shaped landform that forms around the volcano |
They Can be Steep or Gently Sloping depending on the type of Eruption that form them |
Vent
Is the Opening through which an eruption takes place |
this main part of a volcano that supplies the magma(from the underlying source to the top of the volcano) |
