100
Any place where gas, ash, or melted rock comes out of the ground
What is a volcano
100
Broad base Gently sloped
What is shield
100
Two tectonic plates are moving away from each other
What is divergent plate boundaries
100
the “gooeyness” of the lava
What is viscosity
200
Melted rock that has reached Earth's surface
What is lava
200
Pyroclastic materials harden in the air (after an explosion) and fall onto the ground around the vent Build up around the vent forms the cone
What is a cinder cone
200
One plate dives below the other, fluids in it become super heated and escape
What are convergent plate boundaries
200
a volcano that HAS erupted in the past 10,000 years
What is an active volcano
300
Melted rock that is beneath Earth's surface
What is magma
300
Cover wide areas Typically mild eruptions Low-viscosity lava
What is a shield volcano
300
Mantle rock gets hot, and melts into magma A column of hot mantle rock rises to form volcanoes
What is a hotspot
300
a volcano that HAS NOT erupted in the past 10,000 years, but could erupt again
What is a dormant volcano
400
hot ash, dust, and bits of rock that are typically ejected during eruptions
What are pyroclastic materials
400
Created by alternating layers of hardened lava and pyroclastic materials Form into large and steep volcanic mountains
What is a composite volcano
400
Lithosphere stretches and gets thinner, pressure on the rock goes down, asthenosphere (just below the lithosphere) bulges up, and magma forms
What are divergent plate boundaries
400
lava flows from a giant crack in Earth’s surface
What is a fissure eruption
500
a circular dip caused by volcanic activity
What is a crater
500
Can form at a side vent
What is a cinder cone
500
happen when lava flows from a giant crack in Earth’s surface
What is a fissure eruption
500
Most common on the ocean floor (forming underwater volcanoes)
What is divergent plate boundary
