People in an earthquake zone must beware of these after an earthquake hits because some can be quite strong and do significant damage
What are aftershocks
100
These are areas of extra heat caused by rising plumes of hot mantle in the middle of a plate
What are hotspots
100
This type of stream is located in areas of steep terrain and has little to no floodplain
What is a bedrock stream
100
A set of weather patterns is known as this
What is climate
100
This is found when you compare how old something is to the existing features around it
What is a relative age
200
These are the four things that can trigger an earthquake
What are: movement along faults, volcanic eruptions, explosions, impacts
200
These are the three types of volcanoes
What are shield, cinder cone, and stratovolcanoes (composite)
200
This process is in charge of distributing water throughout the globe via evaporation, condensation, and precipitation
What is the water cycle
200
These are narrow air currents that exist between the troposphere and stratosphere and steer fronts and storms
What are jet streams
200
The Mercalli Scale measures the observed effects of a quake and is how we compare this type of magnitude
What is intensity (FM)
300
Distance to a quake can be determined using the difference in arrival times of these two types of waves
What are P and S waves
300
This type of magma has the highest silica content and can be found in many stratovolcanoes that cause large eruptions
What is felsic magma
300
This type of flood requires a larger discharge and is often fed by several tributaries that cause the flood to take days or weeks to develop
What is a downstream flood
300
This type of pressure system is responsible for the most powerful storms and strongest winds
What is a low pressure system
300
These are the two types of physical weathering
What are frost wedging and biological weathering
400
The two primary concerns of people whose houses are built on soft mud, sand, or loose gravel along the coastline are these
What are ground motion amplification and liquefaction
400
Silica content and this are related because as magma increases in silica content, it does not flow as easily
What is viscosity
400
The formula for discharge from a stream is this
What is Q=wdv or Q=Av q=discharge, A=area, v=velocity, d=depth, w=width,

Another name for a low pressure area with closed circulation is this
What is a cyclone
400
This type of beach is often subject to the effects of longshore drift, beach erosion, and storm surges
What is a barrier beach
500
The earthquake in New Madrid, Missouri in 1811 was of particular significance because the town lies here
What is in the middle of a plate
500
This is a type of melting that occurs in subduction zones and produces andesitic or intermediate magma
What is flux melting
500
Two of the secondary effects of a flood are these
What are: contamination of water supply, disease outbreaks, disruption of utilities, disruption of transport networks, loss of crops/animals,
500
The hazard that accompanied Hurricane Katrina and devastated New Orleans in 2005 and is responsible for 90% of global tropical cyclone deaths is this
What is a storm surge
500
This type of lava flow can be very destructive of property, but easily avoided by people
What is a basaltic lava flow
