Question 5

The figure below illustrates the rain shadow effect.  
What best explains why the leeward side of the mountain experiences less rainfall?

Accepted Answer

A) The air mass simply has no more moisture; it was all released on the windward slope. 
B) As the air flows downslope it is compressed and warmed, allowing it not only to retain its own moisture but often removing moisture from the soil beneath as well. 
C) The rotation of the Earth causes the air moving downslope to be displaced to the right, reducing rainfall behind the mountain. 
D) All of the above contribute to the rain shadow effect.

Question 6

Which of the following best explains why a given biome is not found in each location where it could potentially exist?

Accepted Answer

A) Ecologists are presently unable to answer this question; biomes appear to develop randomly and are based on unknown factors. 
B) Biomes consist of unique assemblages of organisms; each biome can occur at only one place on Earth. 
C) Despite the appropriate climatic conditions, the bedrock at any given location may not produce the correct soils that would allow the biome to develop. 
D) Where aquatic and terrestrial biomes meet, no type of biome is able to become established.
