An underwater mountain range, formed by plate tectonics.
What is The Mid-Ocean Ridge
200
Named for their large size and low profile, usually built almost entirely of fluid lava flows
What is shield volcanoes
200
Depending on its composition and temperature, lava can be very fluid or very sticky a.k.a ___
What is a viscous volcano
200
A multitude of dangerous particles and gases, such as aerosols, are carried in this
What is volcanic ash
200
Having a route to follow during an eruption is an example of this.
What is a plan
300
Most volcanoes occur near these, especially near subduction zones where oceanic plates dive under continental plates.
What are tectonic plates
300
Among the most common volcanic land forms found in the world. It has a large amount of silica.
What are cinder cone volcanoes
300
If you are in a volcanic region and an earthquake occurs, what should you be prepared for?
What is an eruption
300
This type of flow can rang anywhere from 200 degrees C to 700 degrees C. They vary in size and speed, will destroy everything in there path, generally follow valleys or other low-lying areas.
