Rock Cycle
naturally occurring solid mixture that makes up earths crust
rock
type of igneous rock formed inside the Earth
intrusive igneous rock
two things that cause metamorphic rock to form
heat and pressure
sedimentary rock formed from the remains of ancient life
organic sedimentary rock
what can only be found in sedimentary rocks
fossils
the process by which wind, water, ice (the water cycle)and gravity transports sediment or other material to a new location
erosion
type of igneous rock formed at or near the Earth's surface
extrusive igneous rock
metamorphic rocks have been . . .
changed
sedimentary rock form from the broken sediments and bits of other rock
clastic sedimentary rock
the grand canyon is made of mostly this rock type
sedimentary
the continual series of geological processes in which a rock changes from one type to another, is destroyed and constructed again
rock cycle
Describe the difference between magma and lava.
Magma is found inside the Earth, while lava is found at or near the Earth's surface. Both are liquid or molten rock.
The two metamorphic rocks we passed around in class today.
marble and gneiss
sedimentary rock formed from minerals dissolved in a solution with water
chemical sedimentary rock
the water cycle causes this
weathering and erosion
the process in which the water cycle and heat break rock into sediment
weathering
The two igneous rocks we passed around class today.
granite and obsidian
metamorphic rock often tells of this
the area being deep underground
process by which the weight of overlying rock presses sediment together into a rock
compaction
this rock has resemblance to other rocks but is hard to identify
metamorphic
too much heat and pressure on any rock will result in this
magma
This type of igneous rock forms the ocean floor
basalt
What has to exist before a metamorphic rock can exist?
Another rock
process by which minerals like quartz or calcite crystallize out of solution after the water is squeezed out by pressure thus "gluing" together the nearby sediments
cementation
dwayne johnson is this type of rock
