100
This is a vent in Earth's crust in which melted - or molten - rock flows
What is a volcano?
100
These are the three shapes of volcanoes
What is a shield volcano, composite volcano, and cinder cone volcano?
100
These are the two main categories of volcanic eruptions
What are non-explosive (quiet) and explosive (violent)?
100
These are the four things scientists test to determine if a volcanic eruption will happen soon
What is measuring gases, measuring earthquakes, measuring temperature, measuring slope?
100
Water is an example of which type of viscosity
What is low viscosity?
200
This is molten rock that flows onto Earth's surface
What is lava?
200

This type of volcano is the lowest in height and is really spread out

What is a shield volcano?
200
This type of effect from a volcanic eruption results in pulverized rock and glass falling to the ground from the sky
What is ash fall?
200

If the volcano is getting hotter, it can mean an eruption may happen

What is measuring temperature?
200
This is the type of volcano that is NOT at a plate boundary
What is a hot spot?
300
This is molten rock that is below Earth's surface
What is magma?
300
This type of volcano is the tallest, has steep sides, and erupts along convergent boundaries
What is a composite volcano?
300
This effect from a volcanic eruption includes snow and ice melt mixing with mud and ash
What is mudflow?
300

If there are more and more vibrations happening, an eruption might occur

What is measuring earthquakes?
300
These are the two types of plate boundaries where volcanic eruptions can occur
What are convergent and divergent?
400
This is a liquid's resistance to flow
What is viscosity?
400
This type of volcano is of medium-height that erupt gas-rich lavas
What is a cinder cone volcano?
400
This effect from a volcanic eruption involves slow moving liquid rock
What is lava flow?
400

If there is an increase in carbon dioxide and sulfur dioxide near a volcano, it may mean an eruption will happen soon

What is measuring gases?
400
This activity is what causes volcanoes to form and erupt
What is tectonic plate movement?
500
These are tiny particles of pulverized rock and glass
What is volcanic ash?
500
This type of volcano is common along divergent plate boundaries
What is a shield volcano?
500
This type of effect from a volcanic eruption results in really hot material flying through the air very quickly
What is pyroclastic flow?
500
If the volcano appears to be "bulging", an eruption might happen soon
What is measuring slope?
500
These are the four types of lava flow AND four types of pyroclastic material
What are lava flow = aa, pahoehoe, blocky lava, pillow lava; pyroclastic material = volcanic bombs, volcanic blocks, lapilli, volcanic ash?
