Air masses formed over the Pacific Ocean are moved by prevailing westerlies where they encounter extensive north- south mountain ranges, such as the Sierra Nevada and the Cascades. Which statement best describes the changes that these air masses undergo?

#Unit 10. Ecological Principles
  1. The cool, moist Pacific air heats up as it rises, releasing its precipitation as it passes the tops of the mountains, and this warm, now dry air cools as it descends on the leeward side of the range.
  2. The warm, moist Pacific air rises and cools, releasing precipitation as it moves up the windward side of the range, and this cool, now dry air mass heats up as it descends on the leeward side of the range.
  3. The  cool,  dry  Pacific air  heats and  picks  up  moisture from  evaporation of  the  snowcapped peaks of  the mountain range, releasing this moisture as precipitation as the air cools as it descends on the leeward side of the range.
  4. These air masses are blocked by these mountain ranges producing high annual amounts of precipitation on the windward sides of these mountain ranges.
