chapter 26.4 Flashcards
metamorphic rock is changed by a combinations of which 3 things
heat, pressure, and chemical reactions
which types of rocks can be changed by metamorphism
igneous, sedimentary or metamorphic rock
what is it called when metamorphic changes in rocks occur over large areas
regional metamorphism
what is it called when metamorphic changes in rocks occur over small changes
contact metamorphism
when shale compressed, which type of metamorphic rock is created
minerals
what are two types of metamorphic rock textures
foliated and non-foliated
define foliated texture
rocks have crystals that are arranged in layers and bands
define non-foliated texture
rocks have crystals with more random orientations
metamorphic rocks are mainly classified based on two things
texture and composition
define rock cycle
The continual changing of rocks from one type to another
which types of rocks are part of the rock cycle
sedimentary, igneous, and metamorphic rocks
what are 3 types of rocks
igneous, sedimentary, and metamorphic
which type of rocks form from molten rock
igneous rock
which type of rocks are formed from clasts, precipitation, or compressed once living matter
sedimentary rocks
which types of rocks are formed from heat, pressure, and chemical reactions
metamorphic rocks
