Foliation indicates that ____ during metamorphism
A)a liquid intrusion flattened crystal patterns
B)magnetic influences were present
C)the rock was subjected to heat and differential pressure
D)the rock was formed deeper in Earth than its nonfoliated counterpart
E)carbon dioxide invaded pore spaces

Question

Quizplus · Accepted Answer

Foliation is the development of distinct layers in a rock due to the application of heat and differential pressure during metamorphism. It results in the alignment of minerals in a preferred orientation, which gives the rock a layered appearance. Foliation is a characteristic feature of metamorphic rocks and indicates that the rock has undergone significant changes due to tectonic forces or high heat and pressure. The other options are not related to the formation of foliation in metamorphic rocks.
