Term
Know the different types of tectonic hazards.
|
|
Definition
Tectonic hazards are geological results of plate shifting exhibited by volcanic eruption, glacial erosion, tsunamis and earthquakes. Earthquakes are the most commonly reported hazards because of the greater likelihood of larger populations along major fault lines than in glacial or oceanic regions.

Term
Know the layering of earth |
|
Definition
The four layers of the Earth are called the inner core, the outer core, the mantle and the crust. In addition, there are two different types of crust. The continental crust is the part that is under land, and the oceanic crust is the part under the oceans.

Term
know the basic tenets of plate tectonics including the types of plate boundaries and their connection to natural hazards. |
|
Definition
There are three kinds of plate tectonic boundaries: divergent, conv[image] ergent, and transform plate boundaries. |

Term
know the different scales of earthquake measurement i.e. mercalli vs, richter |
|
Definition
|
Mercalli Scale | Richter Scale |
Measures |
The effects caused by earthquake |
The energy released by the earthquake |
Measuring Tool |
Observation |
Seismograph |
Calculation |
Quantified from observation of effect on earth’s surface, human, objects and man-made structures |
Base-10 logarithmic scale obtained by calculating logarithm of the amplitude of waves. |
Scale |
I (not felt) to XII (total destruction) |
From 2.0 to 10.0+ (never recorded). A 3.0 earthquake is 10 times stronger than a 2.0 earthquake. |
Consistency |
Varies depending on distance from epicenter |
Varies at different distances from the epicenter, but one value is given for the earthquake as a whole. |
