Learning Targets –
- I need more help with this concept  I understand the basics of this concept
+ I got this!
I can explain Wegener’s theory of continental drift
I know the evidence for sea-floor spreading
I can explain how convection currents power the movement of the plates
I can list and describe the types of plate boundaries and faults and the “stress” that
causes them
I can describe how and where most mountains form
I can draw a diagram of the fault, epicenter, focus and epicenter of an earthquake
I know the relationship between earthquakes, volcanoes and plate boundaries.
I can compare and contrast P, S and Surface waves (order that they arrive, materials
that they can move through, and how they move the rock particles).
I can find the epicenter of an Earthquake using data from seismograph stations and
a compass.
I can compare and contrast the different “scales” used to describe earthquakes
(Richter, Moment Magnitude, Modified Mercalli)
I can explain how volcanoes form
I know why some volcanic eruptions are quiet and others explosive
I can label the epicenter, focus and fault.
I know that the closer a city is to an epicenter the more damage that will occur.
I know that the best way to protect yourself during an earthquake is to “Drop,
Cover and Hold on.”
I can label the hanging wall and footwall of a fault.
I can compare and contrast the different types of faults (normal, reverse, strike-slip
and thrust).
I can draw the movement along the fault for normal, reverse, strike-slip and thrust
faults and know which way the hanging wall moves (up or down). Remember that
a strike-slip fault has no hanging wall or footwall.
I can identify the type of “stress” that is associated with each fault.
I know that the San Andres Fault is an example of a strike-slip fault.
I can identify waves based on diagrams.
I can locate the “Ring of Fire” and know how it got its name.
I can identify the factors that affect viscosity (silica & water content, temperature).
I know how a Tsunami forms and the system that is used to track them.
I can explain how earthquakes can cause liquefaction.
I can label the parts of a volcano.
I can describe how a caldera forms and that Crater Lake is an example of a caldera.
I know the characteristics of a quiet and explosive eruption.
I know which type of eruption form pahoehoe and aa.
I can compare and contrast the 3 types of volcanoes
I can draw a cross section of each of the 3 types of volcanoes and can describe how
each was formed (lava flow or ash & cinders).
I can identify and describe the types of intrusive igneous rocks that can form (sill,
dike, volcanic neck, batholith).
I can describe how a hot spot can create volcanoes (Hawaii).
I can identify the relative age of an island by its distance from the hot spot.
I know that the Earth’s plate move in different directions but hot spots do NOT
move.
I can describe how seismographic data has been used to identify the outer core.
