Astronomers have long accepted that plate tectonics exists nowhere in our solar system except on Earth.
In 2011, a scientist analyzed 100 NASA-space-mission photographs of Valles Marineris on Mars, the
longest known series of canyons in the solar system. The scientist found that Valles Marineris showed
features found only in locations on Earth where major tectonic plates divide. What would be the
appropriate response of scientists to this information? - ANSWER-Carry out further research to gain
more understanding of possible plate tectonics on Mars
According to the theory of plate tectonics, volcanoes are especially likely to form along plate boundaries
because of rising magma. New satellite data mapping the ocean floor reveals thousands of seamounts,
which are small volcanoes. Some of the seamounts are in lines that could correspond to past or present
plate boundaries, but many are not aligned in this way. How should scientists appropriately respond to
the idea that some new mechanism of forming the volcanoes is involved? - ANSWER-Carry out more
research to understand better how the seamounts form
For many decades, scientists thought they understood how ozone breaks down in the stratosphere,
creating ozone holes. However, new data show significantly lower reaction rates than can be explained
by the long-held model. What is the appropriate scientific approach for dealing with this contradiction? -
ANSWER-Conduct additional experiments to confirm the new data
For almost 1500 years most scientists in Europe accepted Ptolemy's geocentric planetary model that
suggested the sun revolved around Earth. By the eighteenth century, most scientists supported a
heliocentric model that suggests that Earth revolves around the sun. What is an appropriate scientific
basis for this change in view? - ANSWER-The existing theory was changed to account for new data
,A woman does pushups by lowering her body to the floor using her arms and then pressing against the
floor with her hands to push herself back up, as shown in the image below. Which force causes her to
rise? - ANSWER-The upward force that the ground exerts on the woman
Two boxes sitting on the floor look identical, but one has more mass than the other. What happens
when the same net force, sufficient to overcome static friction, is applied to each box? - ANSWER-The
box with less mass accelerates more.
Two identical train engines are parked on parallel tracks. One engine has ten cars attached, and the
other has no cars attached. Each engine exerts the same net force, which allows the train to overcome
static friction. Which engine will be able to accelerate more? - ANSWER-The engine not pulling any cars
will accelerate more.
A woman applies an upward force to a basket filled with groceries. Assume she is standing still.
What will happen to the basket if the force she applies is greater than the force of gravity? - ANSWERThe
basket will move up.
A heavy truck and a light car travel at the same velocity side-by-side on the highway. Both drivers apply
the same braking force at the same moment.
What will happen to the two vehicles? - ANSWER-The car will slow down more quickly than the truck.
Which force causes graphite from the tip of a pencil to transfer to the paper? - ANSWER-Friction
Which force keeps Jupiter in orbit around the Sun? - ANSWER-Gravity
Which force causes a jet airplane to stop on a runway? - ANSWER-Friction
Which force causes meteors to burn up when they enter Earth's atmosphere? - ANSWER-Friction
Which kind of electromagnetic radiation carries information to and from a cell phone when it is used for
a phone call? - ANSWER-Microwaves
, A cashier who has been handed a hundred-dollar bill may check its authenticity by holding it under a
special lamp that emits electromagnetic radiation mostly at wavelengths slightly shorter than visible
light. The electromagnetic radiation makes a pattern of previously invisible markings on the bill glow
brightly, or fluoresce. Which kind of electromagnetic radiation does the lamp emit to produce this
effect? - ANSWER-Ultraviolet Radiation
After natural disasters, first responders can locate survivors in the rubble by using thermal detectors.
Because the victims' bodies are warmer than their surroundings, the difference in temperature is
detected by electromagnetic waves. Which part of the electromagnetic spectrum is being detected? -
ANSWER-Infrared radiation
Airport security uses electromagnetic radiation to form images of objects inside passenger luggage.
Which type of electromagnetic radiation is used in this way? - ANSWER-X-Rays
Which type of wave has a longitudinal motion? - ANSWER-Sound waves
Which is a characteristic of electromagnetic waves? - ANSWER-Transverse wave motion
A slingshot is a Y-shaped stick with rubber bands between the prongs for shooting stones and other
small projectiles. A stone is shot by first placing it in the slingshot holder, which is attached to the rubber
bands. The stone and holder and then pulled back, stretching the rubber bands. When released, the
stone is propelled forward and leaves the slingshot at a high speed. Which type of energy
transformation occurs from the point when the rubber bands are fully stretched to when the stone
leaves the slingshot?
- ANSWER-Elastic potential energy is converted into kinetic energy.
Which type of energy conversion occurs at the moment fireworks explode? - ANSWER-Chemical
potential energy is converted into kinetic energy.
What energy conversion takes place as a box slides to a stop on a horizontal table? - ANSWER-Chemical
potential energy is converted into thermal energy.
Which action demonstrates a chemical change? - ANSWER-cooking an egg
