Which is an example of an qualitative observation?

• There are 13 trees

• There are red, blue, and yellow birds

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant

• The amount of sunlight

• The type of music

• The type of liquid

When an experiment is done several times to see if similar results are observed each time.

• qualitative data

• repeated trials

• dependent variable

• constant

A geologist is investigating the history of an area that has experienced various geological events, including sedimentation, erosion, tectonic deformation, and volcanic eruptions. The diagram shows the cross section produced from her study. Which answer correctly explains how the geologist knows the relative age of the intrusion compared with that of the gravel.

• Because the intrusion is an igneous formation and the gravel is a sedimentary formation there is no way know which one is older.

• Igneous rock is always younger then sedimentary rock.

• The gravel is older because it is on top.

• The gravel is younger because it is on top and the intrusion does not cut through it.

A geologist is investigating the history of an area that has experienced various geological events, including sedimentation, erosion, tectonic deformation, and volcanic eruptions. The diagram shows the cross section produced from her study. Which statement correctly explains how the geologist knows that the flow is older than the intrusion.

• Because both the flow and the intrusion are igneous formations it is impossible to tell which one is older.

• Because the flow has been bent by plate movement and the intrusion has not means flow is older because the flow was formed before the plate movement and the intrusion after the plate movement.

• They are the same age because they both start at the bottom of the cross section.

• The flow is older because it stays lower in the cross section and the intrusion starts low and goes higher.

Several fish species became extinct millions of years ago. The graphs show the distribution of fossils of these fishes as they occur in several undisturbed layers of sedimentary rock observable in a cliff face. Which inference can be made about the fish species extinction in figure number 1?

• The steep straight line slope shows a rapid decline in the population of the fish species indicating a rapid change in the environment.

• The steep straight line slope shows a gradual change in the declining population of the fish species indicating the environment changed slowly over time.

• A steep increase in the population of the species cause the resources of the environment to be used up and cause a crash in the population and eventual extinction.

• It is not possible to make an inference about the extinction of the species based on the information in figure number 1.

Several fish species became extinct millions of years ago. The graphs show the distribution of fossils of these fishes as they occur in several undisturbed layers of sedimentary rock observable in a cliff face. Which inference can be made about the fish species extinction in figure number 2?

• The gradual decreasing slope of the line shows a rapid decline in the population of the fish species indicating a rapid change in the environment.

• The gradual decreasing slope of the line shows a gradual change in the declining population of the fish species indicating the environment changed slowly over time.

• A steep increase in the population of the species cause the resources of the environment to be used up and cause a crash in the population and eventual extinction.

• It is not possible to make an inference about the extinction of the species based on the information in figure number 2.

One bar magnet sits on a table, and a rubber band suspends another magnet above it. In the view on the left, the upper magnet is held in place and cannot move. In the view on the right, the upper magnet has been released. How did the potential energy change when the upper magnet was released?

• Magnetic, elastic and gravitational potential energy increased.

• Magnetic, elastic and gravitational potential energy decreased.

• Magnetic and elastic potential energy increased, and gravitational potential energy decreased.

• Magnetic and gravitational potential energy decreased, and elastic potential energy increased.

Instruments located around Earth record seismic wave activity during an earthquake. The epicenter of the earthquake and locations of the four instrument stations around the Earth are shown. Select two statements that explain fewer waves recorded at some stations.

• Part of the Earth's interior bent some of the waves.

• Different materials in Earth reflect some of the waves.

• Some waves are blocked by water on the Earth's surface.

• Weather events near the stations can prevent waves from being recorded.

As magma rises from the mid-ocean ridge, it cools and solidifies. As this magma solidifies, some of the minerals align with Earth's magnetic field. Every few million years, Earth's magnetic field reverses. This reversal is recorded in the magma that solidified after leaving the mid-ocean ridge. In the picture, these magnetic reversals are indicated by dark and light bands. How can scientists tell when the reversals of the magnetic field occurred?

• by measuring the thickness of the different bands of the oceanic crust

• by measuring the distance between the mid-ocean ridge and the ocean floor band

• by measuring the amount of minerals that aligned to Earth's magnetic field in the different bands

• by measuring the strength of Earth's magnetic field recorded in the solidified magma of oceanic crust
