chapter 2 test Flashcards
process rock forms,changes into one type to another,is destroyed, and processed again
rock cycle
metamorphic rock contains minerals that are arranged in plates or bands
foliated
most characteristics of sedimentary rock
stratfication
plains called lava plateaus
extrusive igneous rock
an igneous rock that cools very slowly the texture is
coarse-grained
sedimentary rock is classified into all of the following main characters
Organic
Clastic
Chemical
igneous rock forms when
magma cools and solidifies
a common structure found in metamorphic rock
fold
the process in which sediment is removed from its source and transported is called
erosion
mafic rocks are
dark-colored rocks in calcium,iron, and magneisium
how composition and texture are used by scientists to classify rocks
differences in composition help scientists classify rock. Scientists use differences; textures,size,shape, and position of grains
two ways a rock can undergo metamorphism
contact metamorphism and region metamorphism
why some minerals only occur in metamorphic rocks
only form in certain temps. and pressures
two ways early humans used rocks
tools,weapons, and building materials
do you think that you would find many fossils
no, heat and pressure would destroy it
