Name two processes by which an air mass can be modified and give examples.
 
  What will be an ideal response?

Question 2

Snow does not immediately melt away on a mild spring day because:
 
  A) snow is more resistant to melting when it's been sitting on the ground for a long time.
  B) shortwave radiation from the sun is absorbed but not re-radiated as longwave.
  C) the high albedo of the snow keeps air temperatures cooler.
  D) snow allows more longwave radiation to be absorbed by the air.

Answer to Question 1

Heating from below (cP air moves over the Great Lakes and creates lake effect snow; mT air moves over the land in the SE U.S. and becomes more unstable), cooling from below (mT moves over a snow pack or cold ocean current), evaporation of water from below (cP air moves over the Great Lakes and creates LE snow), lifting over mountains (orographic lift of Pacific mP air).
