1. Chemistry and Earth Science Midterm Showdown

2. Regular round: write your answer on your board, hide your answer, reveal your answer when told. Each right answer is 1 pt. Speed round: write your answer down and put your board up as soon as you have it. First four teams get 2 pts all other teams get 0 pts. Super Speed Round: write your answer down and put your board up as soon as you have it. First four teams get 4 pts, last team has 1 point taken away, all other teams get 0pts.

3. Regular Round What type of boundary is E? What is one feature you would find at E? Divergent boundary: volcano, rift valley, mid ocean ridge

4. Speed Round Energy that comes from the heat energy inside the Earth. Geothermal Energy

5. Regular Round Rock that forms when lava cools and hardens outside the crust. Extrusive igneous rock

6. Regular Round What type of boundary is G? What is one feature you would find at G? Convergent Boundary: volcano, trench

7. Regular Round Put these rock layers in order from Oldest to youngest. E, D, C, F, B, Fault, A

8. Super Speed Round Youngest type of crust, typically the thinnest but the most dense, constantly being destroyed and remade. Oceanic Crust

9. Speed Round Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL Will glycerol sink or float in molasses? Float

10. Speed Round Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL Water has a density of 1.0 g/mL. Will glycerol sink or float in water? Sink

11. Regular Round Explain what causes volcanism at D The oceanic plate subducts and melts back into magma. The magma rises through the crust and erupts.

12. Super Speed Round Rock created as sediments are compacted and cemented together. Sedimentary rock

13. Regular Round During what star stage are the heaviest elements made? Super novas, because of the energy of the explosion.

14. Super Speed Round Rock created when existing rock is changed by heat or pressure. Metamorphic rock

15. Regular round Name one of the sources of heat for the Earth. Particle Impact Gravitational Energy Radioactive Decay

16. Regular Round Liquid Densities: Water 1.0 g/mL Molasses 1.4 g/mL Glycerol 1.3 g/mL Oil 0.9 g/mL Draw a what it would look like if these three were put in a graduated cylinder. Label each layer.

17. Regular Round Define the Law of Conservation of Energy Energy is not created or destroyed it just changes form.

18. Speed Round During what star stage does a star fuse hydrogen into helium? Main Sequence

19. Regular Round Rock that forms when magma cools and hardens inside the Earth Intrusive igneous rock

20. Super Speed Round What is the process called by which two lighter elements collide and form one new heavier element. Fusion

21. Regular Round What is the geologic feature at D? Trench

22. Regular Round Define the Law of Conservation of mass Matter is not created or destroyed it just changes form. Total matter before a reaction is the same as the total matter after a reaction.

23. Regular Round What is the geologic feature at E? Ocean ridge, volcano, rift valley

24. Speed Round Circular movements of magma created by the heating of the mantle by the outer core. They are what cause the tectonic plates to move. Convection Currents

25. Regular Round Explain what causes volcanism at E Plates are pulled apart creating cracks where magma rises.

26. Speed Round Which rocks are the best for radiometric dating? Igneous, because they usually have only parent isotopes when they are made.
