• C. The Earth is tilted at 23.5 degrees.

• D. The Earth is rotating on its axis.

2. A three-step process is shown: Deposition → Compaction → Cementation. Which of these are most likely formed by the process shown?

• A. Glaciers

• B. Mountains

• C. Sand dunes

• D. Sedimentary rocks

3. A student uses the setup shown to investigate ways to speed up evaporation. Which forms of energy are being compared in the student's investigation?

• A. Light energy and electrical energy

• B. Mechanical energy and electrical energy

• C. Light energy and thermal energy

• D. Mechanical energy and thermal energy

4. Butterflies have very long, tubelike tongues. Hummingbirds have very long tongues. Which statement best describes why butterflies and hummingbirds both have long tongues?

• A. Butterflies and hummingbirds both migrate.

• B. Butterflies and hummingbirds are attracted to brightly colored flowers.

• C. Butterflies and hummingbirds eat the same food

• D. Butterflies and hummingbirds have the same predators.

5. Students observe a glass of ice and water. The glass is dry on the outside. After ten minutes students see drops of water on the outside of the glass. Which statement best explains the students' observations?

• A. The water vapor in the air changes to a liquid when it touches the cold glass.

• B. The cold water inside the glass rises and then slides down the outside of the glass.

• C. The ice in the glass melted and caused the water to overflow the glass.

• D. The water moved to the outside surface through tiny holes in the glass.

6. A student prepared a snack that consisted of grapes, pecans, and strawberries sprinkled with white powdered sugar. The student stored the snack in a refrigerator. An hour later the student observed that the powdered sugar could no longer be seen but the fruit and nuts had not changed in appearance. What most likely happened to the sugar in the mixture?

• A. The sugar evaporated at the lower temperature in the refrigerator without causing any changes to the fruit and nuts.

• B. The sugar was more dense than the other foods in the mixture, so it settled to the bottom of the container.

• C. The sugar dissolved in the moisture on the fruit.

• D. The sugar absorbed energy from the nuts and melted into a colorless liquid.

7. To study the water cycle, students add ice cubes to a glass of water. Ten minutes later they observe the glass. On the outside of the glass, students see drops of water. Which statement explains the students’ observations?

• A. Water vapor has become liquid water.

• B. Solid water has become liquid water.

• C. Liquid water has become water vapor.

• D. Solid water has become water vapor.

8. A wagon is pushed and begins to move. As the wagon moves, it slows and comes to a stop. The wagon and the direction it is pushed are shown. What force causes the wagon to stop?

• A. The force of gravity which is acting in the same direction as the arrow

• B. The force of friction which is acting in the same direction as the arrow

• C. The force of gravity which is acting in the opposite direction of the arrow

• D. The force of friction which is acting in the opposite direction of the arrow

9. White oak trees grow to be 24 to 30 meters tall. Their long branches are covered with leaves, and their roots reach deep into the soil to hold the tree in place. White oaks drop their leaves during the winter months. In which ecosystem would forests of white oak trees be most likely to survive?

• A. Ecosystem 1

• B. Ecosystem 2

• C. Ecosystem 3

• D. Ecosystem 4

• A. Competition for resources would be reduced.

• B. Habitats available to animals would be reduced.

• C. Air pollution would decrease.

• D. Water pollution would decrease.
