Slate
Metamorphic Rock formed from Shale.
Extrusive
describes fine-grained igneous rock that forms when magma cools quickly at or near Earth's surface.
composition
the makeup of a rock
Cementation
Sedimentary rock forming process in which sediment grains are held together by natural cements that are produced when water moves through rock and soil
Outer Core
liquid, outside of inner core
magma
melted rock beneath the earth's surface
luster
How light reflects off a rock
Igneous Rocks
examples: basalt, gabbro, pumice, obsidian (uhb>sid>ee>uhn)
granite
a usually light-colored igneous rock that is found in continental crust
sediments
particles of minerals, rock fragments, shells, leaves, bones, and other remains of once-living things
magma reaching earths surface flows from a volcano as
lava
chemical rock
Sedimentary rock that forms when minerals crystallize from a solution.
Rock
a mixture of such minerals, rock fragments, volcanic glass, organic matter, or otehr natural materials
oceanic crust
earths crust located under the ocean
andesitic
What igneous composition is light and dark colored?
Lava
Molten rock that flos from volcanoes onto Earth's surface.
cool
mechanical weathering is faster in a _____ climate.
evaporites
the minerals left behind when water causes them to leave the water
lithification
the process of turning sediment into rock by compaction and cementation
cleavage
split into pieces with smooth regular planes that reflect light
sheets of hanging rock at an angle
Draperies
lithosphere
the solid portion of the earth (
coarse-grained
crystals are large enough to be seen with the unaided eye
cane reeds
tall grass of southern United States growing in thickets
crystal size depends on the amount of time it takes magma in rock to ____
cool
Sedimentary Rock
Rock that forms when sediments from weathering are compacted and cemented.
Sedimentary rocks
usually have more fossils than other rocks
because what's left of a plant or animal was trapped in the layers of the rock
extrusive rock
igneous rock that formed from lava that erupted onto Earth's surface
Weathering
a process by which the day-in and day-out influences of the atmosphere slowly disintegrate and decompose rocks
3 examples of foliated metamorphic rocks
Gneiss, Schist, Slate
crust
the rocky surface that makes up the top of the lithosphere is Earth's
Tastes salty and is whitish to pinkish
rock salt--chemical
What don't non foliated rocks look like?
sheet like rocks
igneous rock
magma in the earths crust that has risin to the surface and cools and becomes solid
extrusive rocks
Igneous rocks that cool quickly on the Earth's surface.
contact metamorphism
a change in the texture or chemical composition of a rock due to contact with magma
Metamorphic into igneous
when melted sediment mixed with magma, it will then become when magma rises from the mantle, cools and solidifies
two types of igneous rock
intrusive rock and extrusive rock
sedimentary
of, pertaining to, or of the nature of sediment.
Extrusive Igneous Rock
rock that forms from the cooling and solidification of lava at or near Earth's surface
A cast is formed when
mud or minerals fill a mold
What are the three types of rocks?
Igneous, Sedimentary, and Metamorphic
Rock Forming Mineral
20 minerals make up most of the rocks of the earths crust
Is a specific volume necessary for magma to form?
No. Only a specific temperature, pressure and minerals.
Let me know if I missed anyone....please I do not want to miss anyone
You GUYS are all awesome and have kind hearts toward me :D thank you!!!!
