Multiple Choice

6. A teacher demonstrates to her students how condensation occurs. She fills a glass beaker with water and several ice cubes. A few minutes later, water droplets can be observed forming on the outside of the beaker. Why did the teacher use a glass beaker for the demonstration?

• F The glass beaker is a poor solid and allows water to travel through the glass.

• B The motor will operate.

• C The motor and buzzer will operate.

• D None of the devices will operate.

Multiple Choice

8 Which statement best describes the processes of weathering and erosion?

• F Weathering and erosion are directly responsible for the breakdown of any type of rock into smaller particles and the carrying away of the loose sediments.

• G Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment.

• H Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea.

• J Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor.

Multiple Choice

9 The picture below shows what happens when two cue balls bounce off the sides of a pool table and head toward each other. What will happen when the cue balls hit each other?

• A The balls will push each other, changing the motion and direction of each ball.

• B The balls will pull each other, changing the motion and direction of each ball.

• C The slower moving ball will pull the other ball, reversing the direction and position of the slower ball.

• D The faster moving ball will push the other ball out of the way, leaving the faster ball's direction unchanged.

Multiple Choice

A student places 200 g samples of clay, sand, gravel, and loam in separate flower pots. The pots are set on a wire rack, and beakers are placed beneath the pots so that water can drip through holes and collect. The student then pours 50 mL of water over the sample in each pot. The student measures the amount of water collected in each beaker within a five minute period and records the data in the table below. Which type of soil was able to retain the most water?

• F Clay

• G Sand

• H Gravel

• J Loam

Multiple Choice

11 Which of the following is NOT an example of a rapid change to Earth's surface?

Multiple Choice

12. A group of students built the circuit shown below. Which of the changes to the electric circuit shown above will cause the lightbulb to light up?

• F Removing the motor so that a stronger current can flow to the lightbulb.

• G Closing Switch 1 so that the current can flow through the lightbulb.

• H Closing Switch 2 so that the current can flow through the lightbulb.

• J Removing the second battery so that a stronger current can flow through the lightbulb.

Multiple Choice

• A Light is refracted as it moves from one medium to another medium.

• B Light can reflect off the surface of the glass.

• C Light can refract as it bounces off the surface of the glass.

• D Light is absorbed by water and reflected off the glass.

Multiple Choice

14 Ms. Chambers had three paper cards with holes punched in them. First, she lined them up evenly and shined a light through the holes. Then, she arranged them up unevenly. See the image below. The failure of light to travel through the series of cards in Series 2 shows that light travels in a —

• F path that curves to the right until it strikes an object.

• G zigzagging path until it strikes an object.

• H path that curves to the left until it strikes an object.t.

• J straight path until it strikes an objec

Multiple Choice

15 A student hiking in a rocky area on a mountain notices that wide, deep cracks have formed in some of the large rocks. Some of the cracks are so large that the rocks have broken apart. Which process most likely caused these rocks to crack and break?
