This is a study guide for your upcoming quiz. Please be sure to look over your notes and handouts. The following topics will be on the quiz:

 

1.  Plate Tectonics

2.  Earthquakes

5.  Volcanoes

4.  Preparing for a disaster

 

1)     For Plate Tectonics you should be able to name, draw, label and explain the four different plate boundaries. These plate boundaries are divergent or seafloor spreading, convergent- folding, convergent subduction zone, and fault/fracture (transform). You also need to know what phenomena each type of plate boundary causes, for example at what type of plate boundary do you find earthquakes and volcanoes? Vocabulary you should be certain to know the definitions to are: plate, ocean ridge, ocean rift, divergent plate boundary, magma, mantle, asthenosphere, lithosphere, oceanic crust, continental crust, convergent plate boundary, folding zone, subduction zone, fault zone, transform plate boundary, and fracture. You also need to know how the rock cycle is affected by plate tectonics, that is how does the plate tectonic theory explain the recycling of rock.

 

2)     For Earthquakes you should be able to explain what earthquakes are, why they occur and the effects of them. Vocabulary you should know is: epicenter, focus, seismic wave, P-wave, S-wave, L-wave, surface wave, seismograph, seismogram, and ~Richter Scale.  You  also need to be able to explain the effects of Earthquakes

 

3)     For Volcanoes you need to be able to name, draw, and label the “typical volcano.” You need to know the three ways that volcanoes are formed: hot spots, subduction zone, and seafloor spreading or divergent plate boundary. You should know why volcanoes erupt and the difference between an active and inactive volcano. Review the three types of volcanoes: shield, cinder cone and composite, and be able to give an example of each type of volcano. Vocabulary that you should know is: magma, lava, vent, lava reservoir, volcanic bomb, pyroclastic cloud, ash, lava flow, crater, cone, shield volcano, cinder cone volcano, composite volcano, lava tube, light-coloured magma. You also need to know about the positive and negative effects of a volcano eruption.

 

4)     Review the information on the handouts given. You should know what to do before, during and after an earthquake. Review what your family should do to help prepare yourselves in case there is an earthquake.

Here are some sample questions to help you study.

 

•   How are mountains formed?

•   Why are the Cascade Mountains volcanic?

•   What volcano is an example of a composite cone?

•   Why is there a “ring of fire” circling the Pacific Ocean?

•   Draw and explain one type of plate boundary.

•   What is a fracture, or fault zone?

•   Label the plate boundaries.

•   What are the types of seismic waves?

•   Explain the differences between the three different types of seismic waves.

•   Explain the difference in magnitude between an earthquake that measures five on the R.ichter scale, and one that measures seven.

•   Label the typical volcano diagram.

•   What is one effect that earthquakes and volcanoes have on people?

•   List five things you should do after an earthquake.

•   What can you do to prepare for an earthquake?
