Passage V

The mineral sets (groups of two or more minerals) in a rock can provide clues to the pressure and temperature conditions under which the rock was formed. The figure shows the pressure, in kilobars (kb), and temperature relationships of six minerals (A, B, C, D, E, and F). As temperature and/or pressure changes, one mineral may react to form another. A given mineral is present only along its respective line and in the field on one side of the line.

28. Which of the following best describes a pressure-temperature change that would cause Mineral C in a rock at Point Z on the figure to react to form Mineral D?

Answer and Explanation

Your Answer is

Correct Answer is F

Explanation

According to the topic description, that is to say, how to make Z enter the ADE area from ACE. It can be achieved by boosting the pressure or increasing the temperature, but the only option is to increase the temperature, which is also possible
