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
|
