Rock type changed by heat and pressure
Metamorphic
300

low
400
How can sedimentary rocks give us information about past conditions?
Preserved mud cracks, ripples, crossbeds, rock composition
400
Where in the crust are metamorphic rocks most likely to form?
Deep within the crust
500
Name 4 properties or characteristics used to classify minerals
Streak, color, luster, cleavage/fracture, density, hardness, fluorescence, acid reaction
500
Rock most commonly found at the bottom of lakes
Sedimentary
500
High silica content means the rock will be ________ in color
Light
500
Sedimentary rocks form by these 3 processes
Pieces of minerals and rocks are cemented together, shells and skeletons of ocean animals are cemented together, dissolved minerals are left behind as water evaportates
500
Some metamorphic changes occur over _____ areas where mountains are forming and temperature and pressure are both high, others occur over _____ areas where magma or lava heats rock or where rocks are under high pressure
Large, Small
