TGT review game
(look at older posts from this unit to review all of the notes too, as well as your own notes!)
Possible exam essay topics:
1. Describe why the asthenosphere “melts” as it comes to the surface of the Earth, and how this relates to the inner and outer core of the Earth.
2. Explain in detail the process used to locate
the epicenters of earthquakes. Why is it
important to locate epicenters, especially if the earthquakes occur over water?
3. Describe how volcanoes can form as a result
of two types of plate boundaries.
4. Describe different types of volcanoes, and
the reasons they form different shapes and erupt differently.
5. Relate the energy released within the Earth’s
interior to movement of continents, explaining all processes involved and the
regions within the Earth involved.
Learning Objectives for this unit:
1. Compare the densities of
oceanic and continental crust using vocabulary (felsic, mafic, intermediate)
and implications when they meet
2. Relate the densities of the
materials found in continental and oceanic plates to the processes that result
in each type of plate boundary (i.e., diverging, converging, transform)
3. Describe the internal
source of energy on Earth that results in uneven heating of the mantle (i.e.,
decay of radioactive isotopes)
4. Illustrate and explain the
convection currents that result from the uneven heating inside the mantle and
cause movement of crustal plates
5. Describe how the energy of
an earthquake travels as seismic waves and provides evidence for the layers of
the geosphere
6. Describe the effects of the
movement of crustal plates (earthquakes, seafloor spreading, mountain building,
volcanic location on planet, hot spots)
7. Articulate the processes
involved in the theory of Plate Tectonics (uneven heating of the mantle due to
the decay of radioactive isotopes, mantle convection currents, movement of
continental and oceanic plates along diverging, converging, or transform plate
boundaries) and describe evidence that supports this theory (correlation of
rock sequences, landforms, fossils, faults, evidence of seafloor spreading)
8. Relate the concepts of thermal energy,
convection, and pressure to the layers inside the Earth, and identify
them.
