CraterBowl-shaped hole
which forms at the top of the volcano.

Lava FlowLava is very hot
when it erupts out of a volcano. The lava flows down the sides of the volcano. As it moves, the lava cools and hardens.

•Volcanoes are classified by:•Their shape•The way they erupt•The materials from which they are formed

•There are three main types of volcanoes that we need to learn about. They are:•Cinder Cone Volcanoes•Shield Volcanoes•Composite Volcanoes
![Page 13: Lets Review……. Magma Chamber Lies inside the earth. Stores hot, melted rock called magma](https://reader035.vdocuments.mx/reader035/viewer/2022062306/5a4d1b4f7f8b9ab0599a7073/html5/thumbnails/13.jpg)
Cinder Cone VolcanoesCone shaped with very
steep sidesRelatively small-
usually less than 300m (984ft)
Built from lava fragments called cinders
Very little lavaEx: Paricutin in Mexico
and Stromboli in Italy

Shield VolcanoesLooks like a shieldLarge mountains with
gentle slopesFormed from lava that
flows slowly from a crack in the Earth’s curst
Ex: Mauna Loa located in Hawaii is the largest volcano on Earth

Composite VolcanoesLooks like and upside-
down V and has steep sides
Formed from the most explosive volcanoes
Eruptions usually occur without warning and can be very destructive
Layers of rock and lavaEx: Mount Fuji which is
located in Japan
