rocks

3 differant types of rocks

TermDefinition
erosion prosses where wind water ice or gravity moves sediment
weathering proccess that breaks down sediment
deposition proccess where sediment drops
composition what a rock is made of
coarse-grained crystals are larger than sand
fine-grained crystals are too small to be seen without a microscope
magma molten rock underground
magma cooled slowly cooling rate of fine grained igneous rock
cooling rate of fine grained igneous rock lava cooled quickly
lava molten rock at the surface of the earth
2 types of igneous rocks intrusive extrusive
intrusive type of igneous rock that forms undergrouned
extrusive type of igneous rock that forms from lava
3 types of sedimentary rocks clastic organic chemical
organic sedimentary limestone with shells
clastic type of sedimentary rock that forms when sediment is glued together
2 forces that create sedimentary rock compaction (pressure) and cementation (gluing)
2 types of metamorphic rock foliated and nonfoliated
foliated Gneiss is a metamorphic rock with stripes (from pressure). What type of metamorphic rock is gneiss?
What forces can cause metamorphic rock to be created? heat, pressure
A rock is a mixture of ______________ (and sometimes organic material). minerals
Where is sedimentary rock formed (what conditions)? underwater
Where is metamorphic rock formed (what conditions) 1. near magma/lava 2. deep underground 3. where 2 plates collide (mountain building)
List the 3 main types of rock igneous, metamorphic, sedimentary
List a few examples of sediment. gravel, sand, clay, pieces of shells
______________ is when sediments are pressed/compressed down because of pressure compaction
_______________ is when sediments are naturally glued together cementation
continuous process in which new rock is made from old rock rock cycle
______________ is the extrusive igneous rock that makes up the ocean floor basalt
__________ is the intrusive igneous rock that makes up the continents and mountains granite
marble is a ___________ metamorphic rock because it does not have any stripes/bands nonfoliated
