1. Plate Tectonics & Seismic Waves TN Ready Review
8th Grade 2019

2. Standards Seismic Waves
(ESS2.2) Evaluate data collected from seismographs to create a model of Earth’s structure.
Plate Tectonics
(ESS2.4) Gather and evaluate evidence that energy from the earth’s interior drives convection cycles within the asthenosphere which create changes within the lithosphere including plate movements, plate boundaries, and sea- floor spreading.
(ESS2.5) Construct a scientific explanation using data that explains that the gradual processes of plate tectonics accounting for
A) the distribution of fossils on different continents,
B) the occurrence of earthquakes, and
C) continental and ocean floor features (including mountains, volcanoes, faults, and trenches).
Natural Resources
(ESS3.1) Interpret data to explain that Earth’s mineral, fossil fuel, and groundwater resources are unevenly distributed as a result of tectonic processes.
Natural Hazards
(ESS3.2) Collect data, map, and describe patterns in the locations of volcanoes and earthquakes related to tectonic plate boundaries, interactions, and hotspots.

3. Main Ideas Seismic Waves Plate Tectonics Natural Resources
I can identify and describe the contents of the 4 layers of Earth.
I can differentiate between the behaviors of p- and s- waves.
I can summarize how Earth’s inner composition is known.
Plate Tectonics
I can identify the 3 different types of plate boundaries.
I can describe the results of plate movement.
I can evaluate statements about the theory of plate tectonics and Pangaea.
Natural Resources
Distribution of minerals, fossil fuels, and groundwater are uneven due to tectonic processes.
Natural Hazards
I can associate the causes of volcanoes and earthquakes with adjacent plate boundaries.
I can describe the convection currents that cause hot spots.

4. Create a Comic Strip! (ESS2.2)
Include the following:
Crust
Mantle
Inner Core
Outer Core
Each layer’s composition
At least 1 character
Pictures with a little color!
Use your knowledge of Earth’s layers, to create a short comic about what a person would see as they traveled towards Earth’s core.

5. Reference Image 1 for Earth’s Layers

6. Reference Image 2 for Earth’s Layers This image shows how the speed of seismic waves changes as they move inward towards Earth’s core.

7. Reference Image 3 for Earth’s Layers

8. Seismic Waves & Earth’s Layers
At what depths (2) do you see significant changes in the speed of the seismic waves shown on Reference Image (RI) 2?
Which two layers correspond with those depth changes?
Which of Earth’s layers are s-waves able to travel through?
On RI 2, why does the data line on the left stop around 2900km? What kind of seismic wave must the left line be showing?
Explain how scientists can use the data seen in RI 3 to create a model of Earth’s layers.

11. Map 2: Plate Boundaries

12. Map 3: Copper Mining Around the World

13. Natural Hazards/Resources (ESS3.2) Questions
1. What changes in and on the Earth could have caused the formation of oil in some areas around the world and not others? a. A concentration of marine organisms in an area of tectonic plate heat and pressure could have caused the development of oil over millions of years. b. A low concentration of pressure and a high concentration of heat would have allowed the remains of marine organisms to decompose at a rate needed to develop oil. c. The uneven formation of oil is caused by the even distribution of heat as the Earth cooled and hardened billions of years ago. d. Because some areas of the world use more oil it has deplenished the supply in that area, but areas with larger supplies of oil are due to the low demand in that area. 2. What patterns can be determined between the type of plate boundary and the location of copper mining sites. a. Copper mining sites are usually found within close range to divergent boundaries b. Copper mining sites are usually found within close range of convergent boundaries c. Copper mining sites are usually found within close range of transform boundaries d. Copper mining sites are usually in close range of transform and convergent boundaries. 3. According to the maps, which of the following would not be the effect of plate tectonic movement or interactions? a. Earthquakes b. Volcanoes c. Hot spots d. Mineral deposits
