rock cycle
types of rocks
fault mountains
folded mountains
"fire" mountains
100
rocks are continually being created or rocks just get recycled over and over?
recycled
100
name the 3 types of rocks
sedimentary, igneous, metamorphic
100
Give an example of a fault mountain.
Grand Tetons
100
what do these mt. look like
rounded mounds
100
why are these mt. called "fire" mountains
formed from erupting volcanoes
200
true or false? once an igneous rock, always an igneous rock?
false
200
what is necessary for metamorphic rocks to form?
heat and pressure
200
What do these mt. look like?
slanted onto each other
200
give an example of folded mt.
Himalayas
200
give an example
Mt. Ranier
300
what causes the rock cycle to occur?
rocks continually move through different environments
300
how are sedimentary rocks formed?
layering of sediment compressed over time
300
True or false: once formed these mountains never get any higher, they shrink in size
false..continue to get higher over time
300
in what direction are the plates moving
into each other
300
what does a domant volcano mean
not currently active
400
true or false: in about 10,000 years all rock will be formed and the cycle with stop/
false
400
igneous rock comes from?
molten lava that cools and crytalizes
400
how does erosion help form these mountains
carve out the peaks
400
could new mt. of this type continue to form?
yes, as plates cont. to move
400
iin the ocean these volcanos create what?
islands
500
in the 1700's, Scottish geologist, James Hutton, did what?
came up with the concept of the rock cycle
500
What type of rock do we mainly have in Ohio?
sedimentary
500
explain process to creat these mt.
crust cracks and earth heaves upward in slanted motion. earthquakes continue to push them up
500
explain process to create these mt.
to plates collide into each other exerting pressure and earth folds upward
500
explain process for the creation of these mt.
as volcanoes cont. to erupt over time, the mt. gets larger and higher
