Vocabulary
This device measures earthquake wave magnitude.
This scale, an updated version of the original, starts at EF0 and ends at EF5, based on windspeed and with cross-referenced damages done.
What is the Enhanced Fujita Scale?
The factor that causes mudflow, a volcano hazard, can also contribute to flooding if the mountain is ice or snow capped.
What is snowmelt?
This scale for rating Hurricane intensity assigns ratings based on wind speed and describes damage done by the storm.
What is the Saffir-Simpson Scale?
The Modified Mercalli Scale rates earthquakes from 1 to 12 based on this factor.
What is damage?
A break in the earth's lithosphere along which earthquakes are likely.
What is a fault?
Due to warm and cold air meeting and mixing over its general location, this area of the United States sees the most tornadoes per year.
What is Tornado Alley?
Also acceptable: What is Oklahoma?
This volcano hazard is a long, streamlike course of molten rock.
What is a lava flow?
The hurricane factor that can cause the most damage.
What is a storm surge?
Along with volcanoes, earthquakes are most likely to occur around this geological feature.
What is a plate boundary?
A weather phenomenon in which dry air suppresses moisture and precipitation, and can make drought worse.
What is high pressure?
In order to be classified as a tornado, a funnel cloud (which is a whirling column of air) has to do this.
What is make contact with the ground?
Deformation, seismic activity, gas emissions, and increased land temperatures are indications of this.
What is eruption?
Because they rely on warm ocean water and the air above it for energy, hurricanes typically lose power as they move over this.
What is land?
Because shaking can move these, and damage their pipes which can lead to explosions, it is best to make sure they are firmly affixed to the floor or wall.
What is a gas appliance?
A measurement of _____________________, each unit on the Richter scale results in 10 times more shaking than the previous unit.
What is magnitude?
In the event of a tornado, the safest place to be is here.
What is a basement or lower level (interior room)?
Although it does not occur along a plate boundary, this is a possible location for the formation of volcanoes - and it can occur on the ocean floor.
What is a hot spot?
This leading cause of weather related death in the US can be caused by the intense rains that accompany a hurricane system.
What is flooding?
Although earthquakes cannot be predicted, scientists can consider one of several factors that make them more likely in an area.
What is geology?
What is history of earthquakes?
What is frequency of earthquakes?
Because of flooding and length of time this type of storm remains over an area, it is considered the most powerful and damaging.
What is a hurricane?
In this type of notification of tornadic activity, all of the conditions are present for tornado formation, but one has not yet been spotted.
What is a tornado watch?
At speeds of 100 km/hr and temperatures of 1000 degrees Celcius, this volcano hazard is incredibly dangerous and happens when an eruption is particularly explosive and violent.
What is pyroclastic flow?
Hurricanes form around this imaginary line, starting off as tropical depressions and turning into tropical storms as they strengthen.
What is the equator?
Although it is not on a plate boundary, this area of weakness in a tectonic plate can be a possible location for earthquakes to occur - especially if one has happened here in the past.
What is an intraplate zone?
