[mp14]

Determine whether a rock formed at the following pressures and temperatures typically would be sedimentary, metamorphic, or igneous. If metamorphic, determine whether the rock would be considered low-, medium-, or high-grade.
 
   Pressure = 1 kb, Temperature = 700 C
   Pressure = 2 kb, Temperature = 100 C
   Pressure = 3 kb, Temperature = 300 C
   Pressure = 4 kb, Temperature = 500 C
   Pressure = 6 kb, Temperature = 1100 C
   Pressure = 7 kb, Temperature = 1000 C
  What will be an ideal response?

Question 2

Desalination plants, such as the one just completed in Tampa Bay,
 
  A) are less expensive than groundwater supplies.
  B) are a sustainable virtually unlimited source of water.
  C) produce enough water for local agricultural crops such as corn.
  D) cause groundwater levels to drop.

Answer to Question 1

Pressure = 1 kb, Temperature = 700 C Metamorphism (high-grade)
Pressure = 2 kb, Temperature = 100 C Sedimentary
Pressure = 3 kb, Temperature = 300 C Metamorphism (low-grade)
Pressure = 4 kb, Temperature = 500 C Metamorphism (medium-grade)
Pressure = 6 kb, Temperature = 1100 C Igneous
Pressure = 7 kb, Temperature = 1000 C Metamorphism (high-grade)

Answer to Question 2

B
