Answer to Question 1

ANS: B
Low pressure forms over heated landmasses during the summer which means high pressure systems in
the ocean. The opposite is true in the winter. The equal proportions of ocean and land males these
systems more noticeable. Information can be found in the section Atmospheric Circulation Generates
Large-Scale Surface Wind Patterns.

Answer to Question 2

ANS: D
The most efficient route to sail from the United States to Europe is a northern route. This allows the
ship to use the prevailing westerlies. In the reverse journey, a southern route would ensure the use of
the more dependable Easterly trade winds. Information can be found in the section Voyaging
Combined with Science to Advance Ocean Studies.
