CSET 215

A science class is studying seeds. They plan to measure the length, height, and mass of different types of seeds. Which of these items should the class use to record their measurements as the class takes the measurements?

• camera

• drawing

• graph

• data table

A scientist used a model to predict the path of a hurricane. The hurricane followed a similar path but did not follow the exact path that was predicted. How does this example demonstrate a limitation of models?

• Models cannot be used to predict things.

• Models can be used to predict weather events before the event occurs.

• Models cannot account for how every factor may suddenly change.

• Models can only be used to show physical structures, not events such as hurricanes.

Which of the following claims about empirical evidence and conclusions is correct?

• Empirical evidence is collected through observation, and conclusions are the results of interpreting empirical evidence.

• Empirical evidence is collected during experiments, and conclusions are collected during engineering processes.

• Empirical evidence is based on the bias and opinions of scientists, and conclusions are based on facts.

• Empirical evidence is important for engineering processes, and conclusions are important for scientific processes.

A geologist is studying three layers of sedimentary rock in an area. The layers have not shifted from their original positions. The geologist records the relative ages of the rocks. The bottom layer is listed as the oldest. The top layer is listed as the youngest. What did the geologist use to determine the relative ages of the rocks?

• mineral content

• radioactive decay

• the law of superposition

• the principle of unconformity

Subduction occurs when one plate slides beneath another plate. The figure below shows the process of subduction. Notice that the oceanic plate slides beneath the continental plate.

What happens when the crustal plates move as shown in the figure?

• An ocean forms.

• Volcanic mountain ranges form.

• Sea-floor spreading occurs as the oceanic plate moves.

• A transform boundary forms where the subduction occurs.
