Who are "lava fringers"?
100
This is the "rounded up" elevation of Mauna Kea.
What is "14,000 feet"?
200
This is the name for magma when it reaches the surface of Earth.
What is "lava"?
200
Mauna Kea has a bunch of these volcanoes on its flanks or sides.
What are "cinder cone" volcanoes?
200
In terms of lava viscosity, this type from shield volcanoes has low viscosity and looks like rope.
What is "pahoehoe"?
200
This shield volcano is the most active in Hawaii.
What is "Kilauea"?
200
This near-by mountain is volcanic and apparently fun to ski!

Magma is considered to be less "this", therefore it rises to the surface.
What is "dense"?
300
Mt. St. Helen's is an example of this type of volcano. They are usually very tall and explosive.
What is "composite volcano"?
300
This substance had the highest viscosity in our lab trials.
What is "hand sanitizer"? (for most groups!)

This is the oldest of the Hawaiian islands commonly visited.
What is "Kauai"?
300
This is the name for the ash, rocks, lava and dirt that shoots out of an exploding volcano.

This is the name for an area or zone where one plate goes under another.
What is "subduction zone"?
400
This the name for the biggest divergent boundary home to underwater volcanoes.
What "Mid-Atlantic Ridge"?
400
This is the relationship between temperature and viscosity for most liquids.
What is "higher temperature results in lower viscosity"?
400
All sorts of creatures adapted to cave life live in these underground areas in Hawaii.
What are "lava tubes"?
400
This is the name for the remains of the center of a volcano. The rest was eroded away.
What is "volcanic neck"?
500
This is the common name for a volcano that forms away from a plate boundary, Hawaii is an example.
What is a "hot spot"?
500
These two types of volcanoes are found on the island of Hawaii.
What is "cinder-cone and shield volcanoes"?
500
This type of volcano has high viscosity, granitic lava and low viscosity basaltic lava.
What is "composite"?
500
This is the name for the sunken circular structure that is still smoking a bit at the heart of Volcano National Park in Hawaii.
What is a "caldera"?
500
This is the name for the structure that can block the opening of a volcano and eventually cause an explosion. Pop!
What is a "lava dome"?
