Question

question 25 2 pts which of the following rocks likely developed under conditions of high confining lithostatic pressure? gneiss schist phyllite marble question 26 2 pts true or false: the trend of volcanic island chains indicates the direction of movement of hotspots over time. true false

Explanation:

For Question 25, gneiss typically forms under high - grade metamorphic conditions which include high confining lithostatic pressure. Schist, phyllite are lower - grade metamorphic rocks and marble is mainly formed by the metamorphism of limestone under heat and pressure but not specifically high confining lithostatic pressure like gneiss.
For Question 26, the trend of volcanic island chains indicates the direction of movement of the tectonic plate over a stationary hotspot, not the movement of the hotspot itself.

Answer:

Question 25: Gneiss
Question 26: False
