VOLCANOES

CINDER CONE VOLCANOES
cinder cone volcanoes are also known as the scoria cone.
Cinder cone volcanoes are made of loose rocks, ash,and debri, that was thrown out durring the erruption.
Cinder Cones volcanoes are the most common volcanoes.
Cinder Cone volcanoes can grow quickly but they don't become giants.
Cinder cone volcanoes are made up of many cinders .
3.
SHIELD VOLCANOES
They could be very large because how short and wide they are.
They are formed by runny lava.
A shield volcano resembles the apperance of a Hawaiian warriors shield.
Many of the largest volcanoes on Earth are Shield volcanoes.
They all come in slightly different varriations than the other
Shield volcanoes have several lava flows which eventually gives them a shape of a warriors shield .
A shield volcano is a volcano filled with flowing magma .

COMOSITE VOLCANOES
Also known as "strato volcanoes" because made of alternating layers.
Comostite volcanoes can grow to be very large.
Most Composite volcanoes form in subduction zones where one tectonic plate goes under another plate.
A Composite volcano is formed over hundreds of thousands of years through multiple eruptions .
They are made up of many layers of hardened lava tephra pumice and ash
Composite volcanoes have very steep slopes forming a symmetrical shape.

Each time they erupt it makes the volcone bigger
7.
LAVA DOME VOLCANOES
Created when small masses of thick lava that can't flow far so it piles up.
Lava domes form from viscous hot thick lava.
Most lava domes form at plate boundaries .
A Lava Dome is a mass that will form when lava piles up on top of a volcanoes vent.
Lava Domes can form anywhere where there is volcanic activity.
They accur on the side of a larger volcano
A lava dome is a mound that will form when lava piles up over a volcanoes vent instead of moving away .
