Chemistry and Earth Science Midterm Showdown

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.
