Answer to Question 1

C

Answer to Question 2

Air masses can cool by expanding, and warm by contracting. Near Earth's surface, air is packed densely by its own weight. Air lifted from near sea level to a higher altitude is subjected to less pressure and will expand. Air becomes cooler when it expands. The opposite effect is also true. Air compressed becomes warmer. Air descending from high altitude warms as it is compressed by higher atmospheric pressure near Earth's surface.
