Final Practice

1. A change has been made to this substance (Figure A). The particles inside it have increased energy and are farther apart after the change. What has caused this change?

• The substance has been cooled
• The substance has been heated
• The substance has been stirred
• The substance has been shaken

10. According to the table and text, which statements are true? Select all that are true.

• Mercury is moving in the fastest orbit of any planet
• An AU is a measurement roughly the distance between the Earth and the Sun
• Uranus is moving in orbit more slowly than Mars
• A planet's orbital speed is related to its distance from the Sun
• The Sun’s gravitational pull is weaker on Venus than on Earth

14. Which planet is closest in size to Earth?

• Mars
• Neptune
• Mercury
• Venus

15. Think about what you have learned about mass and gravity. Which planet is likely to have the strongest gravitational pull?

• Mars
• Neptune
• Jupiter
• Venus

17. The convection currents occur in which layer of the Earth?

• Mantle
• Inner core
• Lithosphere
• Outer core

20. Where does the heat come from that heats the mantle?

• The Sun
• Mid-ocean ridges
• The outer mantle
• The Core

21. Which of these statements are true about the convection currents. Select all that apply.

• Seafloor spreading occurs at convergent plate boundaries
• Heat from the mantle's convection currents makes the crust more plastic and less dense
• Lighter (less dense), warm material rises while heavier (more dense) cool material sinks
• Convection currents play no role in the recycling of earth’s material
• Convection currents do not impact the lithosphere

22. Which statement is supported by the evidence? Select all that are supported by evidence

• Flamingos that eat brine shrimp and algae have a darker coloring
• Consuming carotenoids gives flamingos their dark pink color
• Flamingo coloring is influenced by the environment
• Flamingos in the United States are pale in plumage
• Wild flamingos are always darker than captive flamingos

23. The zookeepers in Ohio want their flamingos to have a brighter coloring. Which would be a good plan?

• The zookeepers should move the flamingos to Florida
• The zookeepers should bring in some darker flamingos to breed with the pale flamingos in hopes of passing their genes to the next generation
• The zookeepers should add brine shrimp and algae to the food of the Ohio zoo flamingos
• An antibiotic should be added to the flamingos’ water so that they can recover from illness
• All of these

24. Liv would like to determine how heating water changes its volume. Liv has hypothesized that water will increase in volume when heated. Question to test: Does heating the liquid change the volume? Liv’s Plan: 1. Pour water into container 2. Seal container 3. Heat the liquid by 10°C 4. Measure the volume of the water 5. Record the results Evaluate Liv’s plan. How could this plan be improved?

• Increase the temperature by 25 °C
• Use an unsealed container
• Set a timer and record the time it took for changes in volume to occur
• Measure the volume of water before it is heated
