1. Types of Volcanoes
By; Anna and Andrea

2. Inside a Volcano (The main parts)

3. Composite Volcanoes -Also Called “Strato Volcanoes”
-Formed by alternating types of lava and rock fragments
-They usually erupt in an explosive way which is caused by a certain type of magma called, “vicious magma”
-The most common type of lava from a composite volcano is Andesite*
-They (Andesite) usually make Composite Cones*

4. Cinder Cone Volcanoes -The most common type of volcanoes
-These volcanoes are steep-sided Basaltic* fragments and are smaller and simpler than Composite volcanoes.
- They form when ash, cinders, and bombs pile up around the vent.
-The volcanoes are melted rock that cooled and formed pebble-sized pieces.

5. Shield Volcanoes -Usually gently sloping
-Built almost entirely of lava flows
-Produced by the action of gas

6. Lava Plateaus
-They are very large areas of basaltic lava with a layered structure.
-Lava makes the structure bigger with every eruption.
They tend To be flat.

7. Calderas
When a volcano is erupting and the lava chamber empties, it can collapse. That forms a caldera.
It’s like a lake but it has an island in the center. That’s the volcano.

8. Thanks For Watching!!
We hoped you learned a lot from our short little power point. See you next time on. ALL ABOUT VOLCANOES!!!
