How can some of the impacts of earthquakes be reduced?
by building structures that can sway with the motion
by building structures that do NOT move with the motion
by using thermometers to measure ground temperatures
by using satellites to monitor warning buoys in the ocean
what can scientists measure to help predict when a volcano might erupt?
temperatures of lava flows
lengths of nearby fault lines
small earthquakes and gases in the air near the volcano
increases in severe weather
Which of these is the best design solution for a building in an area with many earthquakes?
one that is rigid and anchored to the ground
one that hangs over a concrete core
one built on soft soil
one that has many windows
Some engineers want to see how different building designs might withstand a strong earthquake. What is the best way to determine this?
Test one building during different earthquakes.
Study past earthquake strengths on a graph.
Test multiple model buildings for one model earthquake.
Construct a real building to observe during an earthquake.
Which of these is the result of erosion by gravity?
a rock arch
a landslide
a sand dune
a fossil layer
A mountain area in the Pacific Northwest has many landslides. What most likely causes these rocks and soils to erode?
tree roots
gravity and rainfall
glaciers
frequent volcanic eruptions
What is one cause of earthquakes?
weathering by glaciers
movements along faults
deposition by moving water
tsunamis forming in the ocean
Which statement is true?
All earthquakes are very dangerous.

Some earthquakes cause roads to buckle.
Some earthquakes are caused by landslides.
Many things can break rocks into smaller particles and move them around. What changes rocks into large, U-shaped valleys?
glaciers
heavy rain
strong winds
winding rivers

Tsunamis are natural hazards. Which statement about these hazards is true?
They can be prevented if they are not too large.
They can never be detected before they reach land.
They can cause an underwater volcanic eruption.
They can destroy entire villages and other structures.
Why are tsunamis dangerous?
They cannot be detected.
They increase in height near the shore.
They cause earthquakes on land.
They are very tall in the deep ocean.
Which can be used to possible detect and reduce the impact of a volcanic eruption?
anchors
satellites
floating buiys
seismometers

Evacuate when they see a lava flow reaching their home.
What is one hazard that can be cause by a volcanic eruption?
tornadoes
air pollution
weathering of rocks
blizzards
