100
This is the term for how resistant a fluid is to flow.
What is viscosity?
100
The lava flow coming out of the volcanoes in Hawaii is characterized by a low this.
What is low viscosity?
100
Volcanologists use this to monitor whether a volcano is "growing" or not. It can also be used to find directions in a car.
What is a GPS?
100
When a volcano erupts, this dense cloud of super hot gases and rock fragments that tends to follow valleys, can burn everything in it's path.
What is a pyroclastic flow?
100
Non-volcanic mountains are formed by the convergence of what kind of plates?
What are continental plates?
200
Explosive volcanoes tend to have large amounts of this in their magma, which causes a massive build up of pressure within the volcano.
What is gas?
200
The fact that the Hawaiian Islands form a straight line is an indicator that this is moving.
What is the Pacific oceanic plate?
200
These are small ponds or lakes that are on or near volcanoes that are warmed by rising magma. These bodies of water tend to get warmer as magma rises.
What are hot springs?
200
When heat from an eruption melts snow and ice, it can result in this disaster.
What is a mudflow?
200
After a volcano has erupted and the magma cools to form land, the resulting land is rich in this, making it a good place for plants to grow.
What are minerals?
300
80% of all active volcanoes above sea level are here, an area around the edges of the Pacific Ocean.
What is the Ring of Fire?
300
The oldest Hawaiian islands are the ones that are in this cardinal direction, compared to the others.
What is northwest?
300
As magma in a volcano moves up, the surrounding rock can become unstable and cause this natural disaster.
What is an earthquake?
300
Parts of a volcano can collapse during an eruption, resulting in this phenomena characterized by a rapid downhill movement of heavy material.
What is a landslide?
300
This is a type of hot spring that erupts.
What is a geyser?
400
This is the result of rising incredibly hot magma from the earth's core that makes its way to the mantle. It is also responsible for the phenomenon known as "hot spots."
What are mantle plumes?
400
This is where a column of hot material rises from deep within the a planet's mantle and heats the lithosphere above it, often causing volcanic activity at the surface, is thought to be responsible for the formation of the Hawaiian islands, and lies directly above a mantle plume.
What is a hot spot?
400
You might find this gas that smells like rotten eggs coming out of a volcano that is close to erupting.
What is sulfur dioxide?
400
This weather related phenomena that can occur as a result of an erupting volcano is the result of the pollution that a volcano can create. It often affects areas far from the erupting volcano.
What is acid rain?
400
This is a type of hot spring that forms at spreading centers in the ocean and expels black mineral rich water.
What are deep-sea vents?
500
Magma in a volcano rises due to the fact that, compared to the rock around it, it is less this.
What is dense?
500
The flow-y nature of the lava that comes from the volcanoes in Hawaii results in the formation of these kinds of volcanoes.
What are shield volcanoes?
500
Due to large amounts of gas pressure and the high temperature of the magma, you might expect this to be coming out near the top of a volcano that is going to erupt.
What is steam?
500
This natural disaster can be caused by and landslide or earthquake that came as a result of a volcano erupting and can harm places far away from the erupting volcano.
What is a tsunami?
500
Magma forms from the subducted oceanic plate with the help of this liquid that travels with the plate down towards the mantle.
What is water?
