How does cooling time effect grain size in igneous rocks?
as magma or lava cools and hardens
time and pressure causes compaction and cementation
when rock material is disintegrated and decomposed
organic sedimentary rocks
parent rock is weathered into smaller pieces
all three types (sedimentary, igneous,and metamorphic) can become metamorphic rocks
the faster the rock cools the smaller the grain size
because is is formed by both a chemical process (evaporation of disolved minerals) and contains organic material
How do igneous rocks form?
