200
A huge hole left behind when a volcano collapses
What is a caldera?
300
Type of volcano built by alternating layers of lava flows and ash flows; can be very explosive
What is a composite volcano?
300

A type of boundary when 2 plates move away from each other creating a volcano

What is a divergent boundary?
300

A type of boundary when a continental plate and oceanic plate collide creating a volcano on the continent.

What is a convergent boundary?
300
Type of volcano that produces both lava and ash, cinder, and bombs
What is a composite volcano?
300
A long tube that connects the magma chamber to the surface

What is the North American Plate and the Pacific Plate?
500
Theory that helped scientists understand how and where volcanoes erupt
What is the Theory of Plate Tectonics?
500

Process in which magma is formed when the oceanic plate sinks beneath the continental plate and melts.

What is subduction?
500

Term used for a volcano like Kilauea which is fully capable of erupting
