Volcanoes
Quakes & Tsunamis
Potpourri
Weathering
Floods
100
A bubble of magma that is very near earth's surface. This feature created the Hawaiin Islands
Hotspot
100
This happens to a tsunami as it nears shallow water
Slows down and gets higher (stacks up)
100
Explain one piece of evidence that supports the theory of plate tectonics
Coastlines Fit Together Fossils Found on Multiple Continents Ages of Ocean Floor Locations of Earthquakes & Volcanoes
100
When water gets into the cracks of a rock and freezes, it can break the rock apart. What is this process called?
Frost Wedging
100
This is generally the cause of floods
Excessive rain/snowmelt
200
A river of mud that is a serious volcanic hazard. These usually occur on mountains where there is a lot of snow and ice, like Mt. Rainier.
Lahar
200
Earthquakes tend to occur at these locations
On faults/plate boundaries
200
Often forgotten as a part of weathering/erosion, this is possibly the most important.
Gravity
200
This specific data is important because it tells us the frequency of specific size floods, so that they can essentially be predicted.
Recurrence Interval
300
The amount of the United States that would be covered if the Yellowstone Supervolcano were to erupt.
Half of the United States
300
This causes a tsunami to form
Displacement of water from landslide/plate shifting (earthquake)
300
This type of weathering actually changes the composition of materials to break it down, as opposed to just using "brute force"
Chemical Weathering
300
List two possible methods used to control floods
Dams Levees Channels/Channelization
400
Four benefits of volcanoes
Rich Soil, Geothermal Energy, New Land, Air
400
Normal waves are usually caused by this; quite different from the way tsunamis form.
Wind
400
A benefit of floods
Creates rich soil for farming
500
The reason that the Yellowstone supervolcano is considered so dangerous, asides from the fact that it is HUGE (50 x 30 mile crater)
It could erupt at any time (it is overdue)
500
There are two main types of earthquake waves. What are they?
Primary (P) Waves and Secondary (S) Waves
