Global wind patterns caused by convection currents in Columbus’s day greatly
affected the weather for ships sailing across the ocean. These same convection
currents cause similar winds today.
What can we expect the winds to be like five hundred years from now?
A. Very similar wind patterns because the same natural laws will govern
convection currents then.
B. Very similar laws control conduction, so air touching the north pole will
cause different winds.
C. Very different wind patterns because the greenhouse effect is changing
laws that govern convection currents.
D. Very different wind patterns because the environment is being destroyed by
careless people today.

Study the chart above and use your knowledge of heat transfer to explain why
the material insulated by polyester beads loses more heat at first.

B. Air space around the beads absorbed heat at first.
C. Polyester beads are unpredictable as an insulator.
D. This chart is obviously an example of poor recording skills.
