Explosive Pyroclastic
A volcano is a mountain
formed beneath the ground when
the Earth’s crust meets the mantle
and magma collects there until
it rises to the surface
because magma is less dense
than the surrounding rock is.
Then the magma becomes liquid.
Shield, cinder cone, and composite volcanoes
Explosive – pyroclastic
Now everybody knows
Shield, cinder cone, and composite volcanoes
Non-explosive lava flows
Now everybody knows
When the water content in
the magma is higher, then
the volcano is more likely
to erupt explosively.
Composite, also known as
stratavolcanoes, form as
explosive eruptions are
followed by flowing lava.
Shield, cinder cone, and composite volcanoes
Non-explosive lava eruptions
form shield volcanoes
Shield, cinder cone, and composite volcanoes
Cinder cone from pyroclastic
are steep but quickly erode
