Compare and contrast the wet adiabatic lapse rate with the

Question

Question: Respond to the following questions in separate paragraphs:

1. Compare and contrast the wet adiabatic lapse rate with the dry adiabatic lapse rate. 
2. When do you use the dry adiabatic lapse rate as opposed to the wet adiabatic lapse rate? 

Both responses combined need to be very short. I just need to get an understanding of how these things interact. Just a very basic, not copied from dictionary, explanation of what these things are and how they compare and contrast to one another.
