Which type of volcanic eruption is considered to be safer because it's "flowy"?
Non-Explosive Eruptions because they contact lava!

What is the name of the volcano responsible for the destruction at Pompeii?
Mount Vesuvius

What are the four types of pyroclastic materials?
Four Types: Blocks, Bombs, Lapilli, and Ash
200
What are the three types of boundaries?
Transform, Divergent, Convergent

An earthquake measured at 3.6 R, what is its MM?
If the Richter is 3.6, the Momentum Magnitude would be:
R x 31.7= MM so....... 3.6 x 31.7 = 114.12

What should you do when you are in a building during an Earthquake?
Drop! Crouch! Hold!

In Dante's Peak, what was "Spider Legs"?
A robot used to get closer to the volcano by climbing down into the central vent.
300
What are the four types of lava?
Four Types: Aa! Pahoehoe, Blocky, and Pillow
300
Which of the three boundaries is not associated with volcanic activity, but is associated with earthquakes?
The transform boundary that moves from side to side
300
What are the two methods of recording earthquakes? How do they differ?
The Richter Scale and the Momentum Magnitude measure Earthquakes. The Richter Scale is better for smaller quakes, and the Momentum Magnitude is better for bigger quakes.

What should you do if you are in your car during an Earthquake?
Stop the car and stay there.... and jam out, safely

If they aren't near a plate boundary, how where the Hawaii Islands formed?
The Hawaii Islands were formed over a Hot Spot, which is a weak spot in the crust that allows magma to poke through forming volcanic features
400
What are the four predicting signs for a volcanic eruption?
Four signs: quakes, smell of gases, increase temps, change in shape of the volcano
400
The "Ring of Fire" surround which massive plate?
The Pacific Plate!

The tool/machine used to record earthquakes is a _______________, and the unit that they record is a _______________.
The tool/machine used to record earthquakes is a seismograph, and the unit that they record is a seismogram.

In Herculanuem, many of the people hid in this place hoping it would shield them from the ash and other volcanic debris.
They hid in the boatsheds.
400
What was the nickname for the woman who's remains they found in Herculaneum that Dr. Richard later reconstructed?
Her nickname was "Bella Donna"
500
What are the three types of Volcanoes?
The three types: Shield, Cinder Cone, Composite
500
How do convection currents of the mantle aid in the movement of plate tectonics?
(Draw it, too!)
Answer, the magma goes from the hot core to the cooler crust in a circular pattern that the plates "ride" on.
500
What are three other natural disasters associated with earthquakes?
Natural Disasters:
Tsunamis, Floods, Gas Leaks, Fires, Mudslides, Avalanches
500
What is the device placed on/near the roof of buildings to prevent damage during an Earthquake?
The Mass Damper
