TRANSCRIPT
• 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.
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
Regular Round• Rock that forms when lava cools and hardens outside the
crust.• Extrusive igneous rock
Regular Round
• What type of boundary is G? What is one feature you would find at G?
• Convergent Boundary: volcano, trench
Super Speed Round• Youngest type of crust, typically the thinnest but the most
dense, constantly being destroyed and remade.• Oceanic Crust
Speed Round• Liquid Densities:Water 1.0 g/mLMolasses 1.4 g/mLGlycerol 1.3 g/mLOil 0.9 g/mL
• Will glycerol sink or float in molasses?• Float
Speed Round• Liquid Densities:Water 1.0 g/mLMolasses 1.4 g/mLGlycerol 1.3 g/mLOil 0.9 g/mL
• Water has a density of 1.0 g/mL. Will glycerol sink or float in water?• Sink
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.
Regular Round• During what star stage are the heaviest elements made?
• Super novas, because of the energy of the explosion.
Super Speed Round• Rock created when existing rock is changed by heat or
pressure.• Metamorphic rock
Regular round• Name one of the sources of heat for the Earth.• Particle Impact• Gravitational Energy• Radioactive Decay
Regular Round• Liquid Densities:Water 1.0 g/mLMolasses 1.4 g/mLGlycerol 1.3 g/mLOil 0.9 g/mL
Draw a what it would look like if these three were put in a graduated cylinder. Label each layer.
Regular Round• Define the Law of Conservation of Energy• Energy is not created or destroyed it just changes form.
Regular Round• Rock that forms when magma cools and hardens inside the
Earth• Intrusive igneous rock
Super Speed Round• What is the process called by which two lighter elements
collide and form one new heavier element.
• Fusion
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.
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
Regular Round
• Explain what causes volcanism at E• Plates are pulled apart creating cracks where magma rises.
