1 JEOPARDY REVIEW Forces Motion NewtonPlate Tectonics Geologic History FJ

2 When you push a penny across a table, the penny will slide and eventually come to a stop. What forces brings the penny to a stop? A. Gravity B. Friction C. The air D. The force of the table B. Friction

3 How can the force of friction be decreased to make it easier to move an object across a metal table? A. Place sandpaper between the block and table B. Place oil between the block and table C. Change the surface to rubber D. Change the surface to wood B. Place oil between the block and table

4 The mass of the Washington Monument would be A. Greatest in Washington DC B. Greatest at the North Pole C. Greatest on the moon D. The same at all locations D. The same at all locations

5 Why does a person weigh less at the top of a mountain than at the base of the mountain? A. The person has less mass at the top of the mountain B. The person has more mass at the top of the mountain C. The person is farther from Earths center when at the top of the mountain D. There is less air pressure at the top of the mountain C. The person is farther from Earths center when at the top of the mountain

6 What must be done to increase the velocity of a rocket traveling in space from 32,000 km per hour to 40,000 kph? A. Increase the rockets mass B. Decrease the rockets mass C. Increase the force acting on the rocket D. Decrease the force acting on the rocket C. Increase the force acting on the rocket

7 The formula v= a x t (velocity equals acceleration multiplied by time) is used to determine the velocity of free-falling bodies. As time increases, the velocity A. increases B. decreases C. Remains the same D. Increases then decreases A. increases

8 At school, a teacher dropped a penny and a crumpled piece of paper from a third floor window. The penny hit the ground first. Why did the penny hit the ground first? A. The penny has greater mass B. The penny weighs more than the paper C. The crumpled paper has greater air resistance D. The penny has greater air resistance C. The crumpled paper has greater air resistance

9 To travel the same distance in half the time, the speed of a moving object must be: A. doubled B. tripled C. quadrupled D. halved A. doubled

10 An ant crossed 3 meters of sidewalk in 3 minutes. What was the ants speed? A. 1 meter/3seconds B. 9 meters/3 minutes C. 1 meter/ minute D. 3 kilometers/hour C. 1 meter/ minute

11 An object falling through a vacuum is affected only by the force of A. Air resistance B. Gravity C. Velocity D. mechanics B. Gravity

12 When a golf ball is placed on a tee, it will remain there until a golfer strikes the ball. This example demonstrates the part of Newtons first law that states: A. A body at rest remains at rest unless acted upon by an outside force. B. A body in motion remains in motion unless a force affects it C. A large force is required to move a large mass D. Every action has an equal and opposite reaction A. A body at rest remains at rest unless acted upon by an outside force

13 Esther pushed her model sailboat across a pond. According to Newtons first law, the sailboat should have continued straight across the pond but didnt. The most likely reason for this was that: A. The force of the wind changed the sailboats direction of motion B. Fish swimming near the sailboat changed its direction of motion C. The force of the water changed the sailboats direction of motion D. The sailboat increased its acceleration across the pond A. The force of the wind changed the sailboats direction of motion

14 A pitcher on the Cleveland Indians baseball team exerted a pushing force when throwing a pitch to a batter. The batter took a swing but missed the ball. The force that eventually changed the motion of the ball was most likely A. Air friction B. Gravity C. The catchers mitt D. The swinging bat C. The catchers mitt

15 A CO 2 cartridge was mounted on the top of a toy car; with the nozzle of the cartridge pointing towards the back. When the gas was released the car moved 6 meters across the room and stopped. The reaction of the car to the release of the gas was to move A. Sideways B. backward C. forward D. upward C. forward

16 A CO 2 cartridge was mounted on the top of a toy car; with the nozzle of the cartridge pointing towards the back. When the gas was released the car moved 6 meters across the room and stopped. The reaction of the car supports A. Newtons first law – a body in motion remains in motion unless a force acts on it B. Newtons third law - every action has an equal and opposite reaction C. Both Newtons 1 st and 3 rd law D. Neither Newtons 1 st nor 3 rd law B. Newtons third law every action has an equal and opposite reaction

17 What is the name of the theory that states Earths crust is broken up into large pieces that move and interact? A. Natural selection B. Mountain building C. The rock cycle D. plate tectonics D. plate tectonics

18 Major Mountain ranges are formed when crustal plates A. Push into each other B. Slide past each other C. Move away from each other D. Break into smaller plates A. Push into each other

19 Which finding provided early evidence for the theory of continental drift? A. Observing that continents fit together like jigsaw pieces B. Identifying major earthquake zones and volcanic belts C. Measuring the distance across the Atlantic Ocean D. determining the age of rocks under the Atlantic Ocean A. Observing that continents fit together like jigsaw pieces

20 What do you predict will happen to the Atlantic Ocean if seafloor spreading continues along the Mid-Atlantic Ridge? A. It will become wider B. It will become narrower C. It will become deeper D. It will remain the same A. It will become wider

21 What mechanism is thought to be responsible for seafloor spreading and plate tectonics? A. Mid-ocean ridge volcanoes B. Convection currents in the mantle C. Earthquakes at the edge of plates D. Earths magnetism B. Convection currents in the mantle

22 By studying folds and faults in rocks, scientists can determine the A. Absolute age of the rocks B. Order of past geologic events C. Depth of the ocean when the rocks formed D. Life forms that lived when the rocks formed B. Order of past geologic events

23 The geologic timetable is divided into three large time units called eras. Which factor were these time divisions based upon? A. Volcanic and earthquake activity B. Locations where rocks are found C. Equal units of geologic time D. Major changes in the life forms D. Major changes in the life forms

24 The geologic eras are made up of smaller time units called periods. What are these divisions based upon? A. Geologic events only B. Biological changes only C. Geologic and biological events D. Equal units of geologic time C. Geologic and biological events

25 What type of rock are most fossils found in? A. igneous rocks B. Sedimentary rocks C. Metamorphic rocks D. Volcanic rocks A. Sedimentary rocks

26 Which method is most reliable in correlating rocks from two different locations? A. Identifying physical characteristics B. Identifying mineral content of the rocks C. Identifying similar fossils in the rock layers D. Identifying the thickness of the rock layers C. Identifying similar fossils in the rock layers

27 FINAL JEOPARDY The acceleration rate of a free-falling object near Earth is 9.8 m/s 2. How would this compare with the acceleration rate of a free-falling object at 10km above the Earths surface? The acceleration would be less because the distance between the center of the object and the center of the Earth is greater so the gravitational force is less.
