What is weathering?
The movement of rock pieces from one place to another
The process of rocks breaking down into smaller pieces
The reshaping of the land by wind and water
The reaction of rain with carbon dioxide
What is erosion?
The reaction of rain with carbon dioxide

They scrape against larger rocks and wear them down
They react with carbon dioxide in the air
They dissolve in water and wash away
What causes wind to blow and rain to fall?
Chemical reactions
Volcanic activity
Energy from the Sun
Melting of glaciers
What is a lahar?
A sudden eruption of a volcano
A slurry-like mixture made of water, ash, and debris
The movement of rock pieces from one place to another
The reshaping of the land by wind and water

Which of the following was NOT a warning sign that the Mt. St. Helens was about to erupt?
A bulge on the north side of the volcano
A huge thunderstorm
Earthquakes
Gases coming out of the vent of the volcano
What technology has advanced dramatically since the eruption for better monitoring of volcanoes?
Satellite imaging
Underwater drones
Sonar
GPS monitors
Which of the following was a major impact of the volcanic eruption of Mt. St. Helens?
Congress cut funding for scientists to study volcanoes.
People decided to not ever live within 50km of Mt. St. Helens.
Roads became unpassable due to landslide debris and volcanic ash
The trees started to immediately grow back through the ash.
What is the primary function of a seismometer?
To measure atmospheric pressure
To detect tiny volcanic earthquakes beneath a volcano's surface
To predict the exact time of a volcanic eruption
To measure the temperature of lava
Volcanic earthquakes are triggered by what?
The eruption of a volcano
The movement of tectonic plates
The movement of magma within a volcano's magma chamber
The cooling of lava on the volcano's surface
What do seismograms help us to determine about a volcano?
If it is extinct
If it is the tallest volcano
If it is showing signs it will erupt
If it has a large magma chamber
What is the benefit of sharing seismogram data with local authorities?
They can improve the accuracy of the seismometer
They can provide educational tours about volcanoes
They can warn people about the oncoming danger and potentially save lives
They can use the data for scientific research only
