Rock
is a mixture of minerals,glass mineraloids,or organic matter
Rock Cycle
showing the three types of rock and how they are formed
Igneous Rock
rock formed by the cooling and hardening of molten material from a volcano or from deep inside the earth
Lava
magma that evetually reaches earth's volcano
Intrusive
igneous rocks formed when magma cools below the earth;generally have large mineral grains
Extrusive
igneous rocks are formed when lava cool on or near the earth surface
Basaltic
igneous rocks are dense,heavy, dark-colored rocks that form from basaltic magma
Granitic
igneous rocks are light-colored rocks of a lower density than basaltic rocks
Metamorpic Rock
rocks that have changed due to temp.& pressure increases or that undergo changes in composition
Foliated
a type of metamorphic rock created when mineral grains flatten and lined up in parellel bands
Nonfoliated
a type of metamorphic rock created when mineral grains change,grow ,and rearragge;BUT DONT FORM BANDS
Sedimentary Rocks
form when sediments become pressed or cemented or when sediments precipitate out of solution
Sediments
are loose minerals such as rock fragments,minerals grains,and bits of plants and animals remains
Compaction
a sedimentary rock-forming process that occurs when layers of small sediments become compressed by the weight of layers above
Cementation
a sedimentary rock-forming process in which large sediments are glued together by minerals deposited between the sediments
When magma cools what does it form
intrusive ignegous
folliated rocks have
banding
granite is a
rock
sedimentary rocks are
often found at the earth's surface
what are the pressure and hear that prouduce magma called
radioactivity
detrital roacks are
made of fragments
coal is used as fuel to produce
electricity
Burning waste coal with ___________ creates alkaline ash htaht helps lessen acidic problems
limestone
A rock is
a micture of minerals, mineraloids, glass, or organice material
crystals that form is slowly cooling magma are
large
how is a detril rock named
the size and sgaoe of its sediments
what forms granite
mica, hornblende, feldsper, and quartz
What does the process os congeneration produce
electrical and thermal energy
T/F
Sediemntary layers are recognizable by differences incolor, sediment, size and compostition
true
T/F
All igenous rocks are formed in the same way
False
T/F
Nonfolliated rocks have very narrow banding
False
T/F
Metamorphic rocks can be formed from other metamorphic rocks
True
In a network-tree concept map would basaltic lava be listed under instrusive rocks or extrusive
extrusive
In a network-tree concept map could you list instrusive rocks under rocks that form above or below
below
Shown on photgraph of pumice and one of obsidian how could you distingush between the two rocks
obsidian is smooth and pumice is full of holes
sandstone
sedimentary
limestone
seimentary
gneiss
metamorphic
obsidian
Igeneous
granite
igneous
slate
metomorphic
rock salt
igneous
How are rocks classified
they are classified by thier formation and compostion
Where does the rock cycle begin
it has no beginning rocks are constantly changing
Why is danerour for rainwater to flow through piles of waste coal
the rainwater gererates acid runoff from the waste coal; the acid rain cause pollution
