Natural/Geologic Hazards
What is a Natural disaster?
A severe weather-related event that threatens health, property, or safety (ex: hurricanes, floods).
What is the scale used to track the magnitude of an earthquake?
Richter Scale
Pangaea
Continents fit together like a puzzle.
Tension
What is a geologic hazard?
A changes to the Earth that cause disasters to occur. (Ex. Tsunami, Earthquake)
Which wave causes the most damage during an Earthquake?
Surface Waves
What layer are the plates a part of? What are all the other layers called
Crust, Upper Mantel, Lower Mantal , Outer Core, and Inner Core
What is the 2nd evidence used to support continental drift?
Similar rock features are found on separate continents.
What type of pressure stress does a Reverse fault have?
Compression
Hazards made because of Earthquakes?
Fire, Tsunamis, Liqefaction, Lansslides/avalanches, Ground Shaking, Surfacce Faulting or breaking.
What are the first two waves called?
Primary and Secondary waves
The plate boundary moves in this direction ---> <----
Convergent Boundary
What is the 3rd evidence used to support continental drift?
What type of pressure stress does a Strike-slip boundary have?
Shearing
Hazards made because of geological Hazards?
Pyroclastic Cloud, Tsunamis, Mud flows- Lahars, Fire, Lava FLows, Earthquake
What are the surface waves called?
Love waves and Rayleigh/Rooling Waves
The plate boundary moves in this direction<---- ----->
Divergent Boundary
Convection currents move the plates around. What layer do the convection currents occur in?
Mantle
This forms because of plates sliding underneath another plate.
Volcanos
The waves released when the earthquake happens.
What is the epicenter?
The location where an Earthquake occurs but at the surface.
The plate boundary moves in this direction ---->
<----
Transform boundary
The Ring of Fire.
Falut lines.
