Volcanoes are formed at plate boundaries. The Earth's crust is split into plates. The most common plate boundary for volcanoes to occur at is a subduction zone at a destructive plate boundary. This is where 2 plate crash head on into each other. If one is heavier than the other (oceanic plates (sea) are heavier than continental plates (land)), which is the case at a subduction zone, then the heavier oceanic plate subducts (goes under) the less dense continental plate. As the oceanic plate sinks, it heats up under pressure, and melts to form magma, which is lava that hasn't erupted yet. The pressure builds up and finally it erupts through a crack in the Earth's crust forming a volcano. When the lava from the explosion run down the sides of the volcano it solidifies, thus building the volcano up.
What else can I help you with?
How does the center of the earth cause a natural disaster?
The mantle is made of lava. When lava makes cracks in the crust it makes a volcano. When the volcano erupts it makes a natrual diaster.
What is extract volcanoes?
extract volcanoes are what makes a volcano a volcano involve CA and CA (cait and cameron) the volcano will be complete
When did the last volcano erupt and what damage did it do?
mayon volcano errupted in January 2010 and makes suffer all bicolanos
Which type of volcano makes up the hawaiian island?
Shield cones
Why is a volcano an extrusive igneous feature rather than an intrusive feature?
A volcano is composed of material that cooled and solidified at the surface, which makes it extrusive.
What makes a Volcano work?
The pressure and heat in the volcano. When to much pressure builds it makes a eruption.
What is a constructive feature of a volcano?
A volcano had plate tectonics that makes a volcano erupt. The tectonic has certain segments, and they are plates.
How does the center of the earth cause a natural disaster?
The mantle is made of lava. When lava makes cracks in the crust it makes a volcano. When the volcano erupts it makes a natrual diaster.
What is extract volcanoes?
extract volcanoes are what makes a volcano a volcano involve CA and CA (cait and cameron) the volcano will be complete
What makes a volcano to erupt?
the hot lava
What does a volcano do for the earth?
It makes the land more fertile
When did the last volcano erupt and what damage did it do?
mayon volcano errupted in January 2010 and makes suffer all bicolanos
What meterial makes up a volcano?
rock. same as a mountain. magma makes up the lava.
How does lava affect the cinder cone volcano?
makes it bigger
What is cladera?
A thing in the middle and top of a volcano that makes it explode
What makes a volcano a shield volcano?
lava that pours out of the vent and hardens on previous layers of lava ( Hawaiian islands / medicine lake)
Which type of volcano makes up the hawaiian island?
Shield cones
