This type of volcano is famous for its explosive eruptions.
What is a composite volcano?
100
Name one positive effect of volcanoes.
What is creating rich soil over a long time, when the lava breaks down? (Another answer: creating new crust).
100
This type of convergent boundary forms folded mountains.
What is continental-continental collision? (Also ok: oceanic-continental subduction)
100
Most activity (earthquakes, volcanoes and mountains) happen here.
What is a plate boundary?
100
This is a hole in the ground that releases steam and other gases.
What is a fumarole?
200
A shield volcano has this kind of magma.
What is silica-poor?
200
Name one way volcanoes can have an effect worldwide.
What is lowering the temperature?
200
Volcanoes in folded mountain belts form when this happens.
What is an oceanic plate partly melts as it goes into the mantle?
200
Hot spots form volcanoes here.
What is in the middle of plates (far from plate boundaries)?
200
A crater-like opening that forms when an explosive eruptions happens and caves in the top of a volcano.
What is a caldera?
300
This is the order of the volcanoes from steepest to the most flat.
What is a composite, cinder cone, and shield volcano?
300
Volcanoes affect water in this way.
What is heating the magma underground by magma that is close to the surface?
300
This is how the folded mountains are formed.
What is a convergent boundary (either continental-continental or oceanic-continental) comes together and it bends or folds the crust?
300
The famous chain of volcanoes that occur along plate boundaries that line the Pacific Ocean is known as this.
What is the ring of fire?
300
Describe the difference between a hot spring and a deep-sea vent.
What is a hot spring is above water and a deep-sea vent is below? The deep-sea vent happens at a spreading center.
400
This is the reason that composite volcanoes are the steepest and tallest of the types of volcanoes.
What is the silica-rich lava that is very thick and moves slowly?
400
Name four negative effects a volcano can have on the land.
What is pyroclastic flow, lava flow, landslide, and volcanic ash? (Answers may vary and can include: Steam explosions, mudflows,...)
400
Describe the formation of the Himalaya mountains?
What is through two continental crusts that come together at a convergent boundary? (Before this took place, it was at an oceanic-continental subduction which created volcanoes, but later collided with another continental crust).
400
Define spreading centers.
What is a place where two plates move apart?
400
These are two positive effects of volcanoes.
What is creating new crust and forming rich soil once that crust is broken down later?
500
A cinder cone volcano is formed in this way.
What is gas-rich lava that erupts and hardens before it reaches the ground? (These cinders and other rock fragments build up around a crater to form a cinder cone).
500
Three effects volcanoes can have on the air.
What is acid rain, changing the temperature, and dangerous gases?
500
Explain how fault-block mountains are formed.
What is the stretching of the lithosphere that breaks the crust into large blocks along faults, that eventually tilt or drop down?
500
Blocks of rock that have tilted along faults are common here.
What is along spreading centers?
500
The formation of a deep-sea vent.
What is an ocean spreading center where two plates are diverging? Cracks form and cold ocean water moves down through them being heated by the magma. It then exits Earth's crust through vents.
