15. True or False: there are 4 types of heat transfer.
Name them!

16. False. There are 3 types of heat transfer: Conduction, Radiation, & Convection.

17. Define Radiation heat transfer. Give two examples.

18. Radiation is heat transfer through space (do not touch directly)
Radiation is heat transfer through space (do not touch directly). Examples: the Sun & camp fire.

19. If the formula for Density is Mass divided by Volume, how can heat change an object’s density?

20. Heat = Energy. Giving an object Energy lets the particles move faster & further away from each other, increasing Volume and decreasing Density.

21. Describe the entire process pictured below.

22. Pot is heated by stove - Conduction
Water is heated by pot - Conduction
Heated water spreads out (energy), +Volume & -Density so it rises.
Spreads out at top of pot, bumps into other particles, -Energy.
Less energy means -Volume, +Density, water sinks.

25. How many pieces of evidence for Continental Drift does the photo below contain? What are they?

26. Three pieces of evidence. A) The continents fit like puzzle pieces
Three pieces of evidence. A) The continents fit like puzzle pieces. B) Mesosaurus fossils were found on both continents. C) Africa & S. America have the same folded mountains.

27. What is Wegener’s Theory of Continental Drift and why was it rejected?

28. The continents were once a supercontinent called Pangea, and are slowly moving, even now. Wegener had no evidence to explain what caused the continents to move.

29. While researching in Antarctica, you discover the fossil remains of the tropical plant of Glossopteris. This plant is native to Australia. What does this tell you about Antarctica?

30. Antarctica once had a tropical climate.
Antarctica and Australia were at one time connected (since the plant can not migrate).
Antarctica once had a tropical climate.

31. What do the reversing magnetic stripes on the ocean floor reveal
What do the reversing magnetic stripes on the ocean floor reveal? Use this information to explain the difference between “magnetic” North and “geographic” North.

32. Stripes tell us that magnetic poles reverse every 300,000 years
Stripes tell us that magnetic poles reverse every 300,000 years. Geographic North is always at 90⁰ North. Magnetic North is where the magnetic field originates.
