7. Unit 5 Review: What is the date in the diagram to the right?a. March 20th

b. June 21st

c. September 22nd

d. December 21st

9. At the beginning of Unit 6, we read four different articles regarding Earth’s interior. A passage from one of the articles is included below. Which article was it taken from?

“But Wegener could never explain how continents could move around the planet. Fast forward about 50 years, scientists began to collect rock samples, fossils, and other evidence. And all of it seemed to support Wegener’s idea. In the modern day, the theory is almost universally accepted.”

a. Mountains (Universe Today, 2015). c. Plate Tectonics (LiveScience, 2017).b. The Science of Earthquakes (USGS, 2018). d. The Volcano Basics (SciNews, 2017).

10. What is the name of the government agency that plans for and responds to natural disasters?a. NASA. b. FEMA. c. DARMA. d. The Red Cross.

Section II: Applying11. Which diagram from our Convection Lab is actually incorrect?

12. Where on Earth would you be likely to find convection currents? a. In the ocean. b. In the atmosphere. c. In the mantle.

d. All of the above. e. None of the above.

13. Which of the pictures below is the most accurate representation of Earth’s atmosphere?

14. The motion of magma inside Earth is known to cause… a. Volcanoes. b. Earthquakes. c. Continental drift.

d. All of the above. e. None of the above.

15. The paragraph below is about our Playing with Fire Lab. Which pair of words below correctly fills in both of the blanks in the paragraph?

“Fire, in general, is simply a ____________ that releases heat. As molecules break apart, they bump into other molecules which then break apart. The

characteristic flame appearance is simply hot air, rising to the temperature at which air glows (977°F), and then floating away and cooling off. In order to

support most fires you need a fuel source (molecules to break down), a supply of oxygen (to support the chemical reaction), and a ____________ (breaking

molecules must produce more energy than they require).”

a. Phase change… proper orbit. c. Mutation… proper orbit. e. Chemical reaction… proper orbit.b. Phase change… net gain in heat. d. Mutation… net gain in heat. f. Chemical reaction… net gain in heat.

16. How do clouds typically form?a. Water from the ocean rises into the sky and is then pushed over the land by wind.

b. Low pressure systems meet high pressure, creating wind; when winds have enough velocitywater gets squeezed out.

c. Warm, moist air is pushed skyward and cools off; the water molecules lose energy and sticktogether, forming droplets.

17. Below is a photograph of the Getz Ice Shelf in Antarctica. How would the wind most likely blow across the Getz Ice Shelf?

18. To the right is a map that shows the "oceanconveyor" currents. The map also points outthree cities: Madrid in Spain, Dakar in Africa,and Marshfield in Massachusetts. Which of thethree cities would be the coldest?

a. Dakar, Africa.

b. Madrid, Spain.

c. Marshfield, MA.

19. Which of the three surfaces below would heat upand cool off most quickly over the course of a day?a. The beach. b. The ocean. c. The forest.

20. On the graph below (taken from Page 611), which line represents the temperature of the ocean?Section III: The Real World (2 points each).
