1. Base your answer to the following question on the weather map below and on your knowledge of Earth science. Theweather map shows a typical low-pressure system and associated weather fronts labeled A and B. The L indicates the centerof the low-pressure system. A few New York State cities are shown. Symbols cP and mT represent different air masses. Thewind direction at Utica and Rochester is shown on the station models.

12. Base your answer to the following question on on the map below, which shows an imaginary continent on a planet that hasclimate conditions similar to Earth. The continent is surrounded by oceans. Two mountain ranges are shown. Points Athrough D represent locations on the continent.

Explain why location C has a warmer and drier climate than location D.

Base your answer to questions 13 through 15 on on the weather map below, which shows a low-pressure system locatedover central United States. Points A, B, and C represent locations on Earth's surface. The isobars on the map show airpressures in millibars.

13. What is the two-letter symbol used on a weather map to indicate the warm, moist air mass that is over point C?

14. What evidence shown on the map indicates that point B is most likely experiencing precipitation?

15. What evidence shown on the weather map indicates that point C is experiencing greater wind speeds than point A?
