Question

question 13 2 pts under which conditions would you expect contact metamorphism to occur? high temperature, high pressure high temperature, low pressure low temperature, low pressure low temperature, high pressure question 14 2 pts which of the following is not a common silicate structure? ring sheet chain isolated tetrahedra

Explanation:

Contact metamorphism occurs mainly due to heat from an igneous intrusion. High - temperature and low - pressure conditions are typical for contact metamorphism as the main agent is heat rather than large - scale pressure changes. Common silicate structures include ring, sheet, chain, and isolated tetrahedra. All of the options for silicate structures are common.

Answer:

Question 13: High temperature, Low Pressure
Question 14: None of the above (since all are common silicate structures)
