Geohazards
100
This is the action which causes earth's tectonic plates to move.
What is convection currents?
100
This type of boundary happens when two plates slide past each other.
What is a transform boundary?
100
This is what letter "A" represents in the diagram, and is where an earthquake starts.
What is the focus?
100
This is molten rock that reaches the surface.
What is lava?
100
This is not a major cause of destruction due to earthquakes.
What is hurricanes?
200
This is the layer of the Earth where convection currents happen.
What is the mantle?
200
A mid-ocean range is evidence of this type of boundary.
What is a divergent boundary?
200
This is the main cause of Earthquakes.
What is the elastic rebound theory?
200
These two things can affect magma's viscosity.
What is temperature and amount of dissolved gas?
200
This is a major cause of destruction due to earthquakes.
What is tsunamis?
What is fires?
What is landslides?
(Any of these are acceptable)
300
The letter C in this graph represents this part of the Earth.
What is the asthenosphere?
300
This type of boundary is represented in this figure.
What is a convergent boundary?
300
P and S waves both travel through Earth, but this type of wave travels faster.
What is a P wave?
300
This is what happens when magma rises through the cracks and lava flows to create new crust.
What is a volcano eruption?
300
This natural disaster is the most unpredictable.
What is earthquakes?
400
This theory helps scientists explain how earthquakes and volcanic eruptions occur?
What is the theory of plate tectonics?
400
The formation of non-volcanic mountains is the result of what type of boundary?
What is continental plates converging with continental plates?
400
This type of wave is the most destructive.
What is a surface wave/L wave?
400
This is where the youngest or newest rocks on Earth can be found.
What is an active volcano?
400
Tsunamis are caused by this.
What is movement of tectonic plates on the ocean floor?
500
This is the theory of plate tectonics
What is "The lithosphere is divided into plates"?
500
The movement of these tectonic plates at this boundary creates this zone, when one plate moves below another.
What is a subduction zone?
500
This diagram of a convergent boundary shows the motion of tectonic plates and represents this type of fault.
What is a reverse fault?
500
This is a mix of water, mud, and rocks that slides from a volcano. .
What is a lahar flow?
500
This is the most effective way to prepare for earthquakes.
What is building strong and flexible structures that protect against ground vibrations?
