A student stacks five different textbooks to represent a model of the major layers of the atmosphere, as shown.

If the physics textbook represents the lowest layer of the atmosphere, which statement is true?

• The ozone layer is contained in the layer represented by the literature textbook.

• The layer closest to outer space is represented by the mathematics textbook.

• All weather activities occur in the layer represented by the history textbook.

• The warmest layer of the atmosphere is represented by the biology textbook.

What is one example of how humans impact global warming?

• Contour plowing by farmers increases the level of rain water run-off.

• Burning coal and oil increases the level of carbon dioxide in the atmosphere.

• The use of copper wire in power transformers increases the speed of the electrical currents.

• Heat emitted from factories, automobiles, and buildings increases the average global temperature.

With less than 5% of the world's population, the United States emits 24% of the world's carbon emissions, while China with 20% of the world's population accounts for 12% of the world's carbon emissions. Based upon this information, what can be inferred about the impact of human population growth on global warming?

• Global warming will decrease as the human population increases.

• An increase in human population results in an increase in carbon emissions.

• There is a direct link between the expanding population and the increase in global warming.

• It is the types of human activities that contribute the most to global warming not just the expanding population.

Volcanic eruptions cause the release of gases such as carbon dioxide, hydrogen sulfide, water vapor, and sulfur dioxide along with soot, ashes, and dust. What is a direct consequence of volcanic eruptions?

• increase in the concentration of greenhouse gases

• decrease in the level of oxygen in the air

• increase in percent of oxygen in the air

• decrease in rainfall

How do transpiration and evaporation compare?

• During both processes, liquid water changes to water vapor.

• During both processes, water vapor changes to liquid water.

• During transpiration, liquid water changes to water vapor, and during evaporation, water vapor changes to liquid water.

• During transpiration, water vapor changes to liquid water, and during evaporation, liquid water changes to water vapor.

Which statement describes the most likely outcome of an interaction between these two sound waves?

• The interaction will result in no sound.

• The interaction will result in destructive interference.

• The interaction will result in half the amount of sound.

• The interaction will result in constructive interference.

The graph shows the orbital speed of the eight planets in the solar system.

Which explanation about the orbital speed of the planets is best supported by these data?

• The orbital speed of large planets is greater than the orbital speed of small planets.

• The orbital speed of gaseous planets is greater than the orbital speed of rocky planets.

• The orbital speed of the outer planets is greater than the orbital speed of the inner planets.

• The orbital speed of the inner planets is greater than the orbital speed of the outer planets.

The magnitude of an earthquake can be measured using data from seismographs and the Richter scale. The Richter scale uses numbers 0 to 9; the larger the number, the stronger the earthquake. The graph shows 40 years of earthquake magnitude data for earthquakes of magnitude 5.0 and greater.

Which statement can a student use to explain the information shown in the graph?

• Lower-magnitude earthquakes are more likely to occur than higher-magnitude earthquakes.

• Higher-magnitude earthquakes are more likely to occur than lower-magnitude earthquakes.

• The past 40 years of data show that magnitude 6 earthquakes are common to all regions of the Earth.

• Over the next 40 years there are likely to be more magnitude 5 earthquakes than earthquakes of any other magnitude.

A student wants to perform an investigation to demonstrate how varying the amount of force affects the speed of a cart on a level surface. Which investigation plan would best demonstrate the relationship between force and speed?

• Plan: Apply an increasing amount of force to the cart over time.

  Results: The speed of the cart increases over time.

• Plan: Push the cart with a constant force over time.

  Results: The speed of the cart decreases over time due to friction.

• Plan: Apply a decreasing amount of force to the cart over time.

  Results: The speed of the cart decreases over time, then increases

• Plan: Provide an initial force on the cart followed by no additional force.

  Results: The speed of the cart remains constant due to inertia.

A student observed a white light bulb while looking through three different sheets of transparent plastic. The student recorded the observations in the data table. Which explanation do these data best support?

• Each plastic sheet absorbs one wavelength of light.

• Each plastic sheet transmits a different wavelength of light.

• Each plastic sheet refracts the wavelengths of light from the light bulb at different angles.

• Each plastic sheet changes the wavelengths of light from the light bulb in different amounts.
