- formed in nature
- is a solid - is non-living - has a crystalline stature
What are the four characteristics do all minerals have?
|
A naturally occurring solid mixture of one or more minerals or organic matter
What is a rock ?
|
- 10-70 km thick
- oceanic and continental
What are the characteristics of the crust ?
|
Pieces of the lithosphere that move on top of the asthenospere
What is a tectonic plate?
|
Cont-cont:
- mountain - moiuntain range Oc-cont: - trench - subduction - volcanoes - earthquake Oc-oc: - trench - subduction zone - islands
What is features do a cont-cont, oc-cont, and oc-oc convergent boundary have?
|
|
- color test
- lust test - cleavage & fracture test - streak test - hardness test - special properties test
What are the seven test that can be performed to identify a mineral?
|
The reformation of rock
What is the rock cycle?
|
- 2,800-3,200 km thick
- 3 main layers - lithosphere - asthosphere - mesosphere
What are the characteristic mantle?
|
Contained where one big landmass called Pangea
What what the theory of continental drift and what was is called?
|
When two plate spread apart making a volcano and a M.O.R
What is a divergent boundrey?
|
|
Diamond and Quarts
What are two minerals that catch scratch Calcite?
|
Little pockets Ina volcano fill with magma and start to slowly cool giving the magma time to form large crystals making an intrusive igneous rock.
What is an intrusive igneous rock ?
|
- 2,100 km thick
- liquid iron and nickel
What are the characteristic of outer core?
|
New oceanic lithosphere forms as magma rises to the surface
What is the process of sea-floor spreading at a mid-ocean ridge?
|
When two plates rub against each others making a fault line
What is a transformation boundry?
|
|
The color of the mineral in powder form
What is streak?
|
When magma comes out of a volcano and start to harden quickly and little time to form crystals making an extrusive igneous rock
What is an extrusive igneous rock ?
|
- Solid ball of iron and nickel
- 1,400 km thick
What are characteristics of the inner core?
|
New- by mid ocean ridge
Old- by the trench
Where is new and old ocean floor located ?
|
Because when the rock is dense it sinks and since there's so much pressure it melts it then rises sinece is light
Explain how convection currents are able to move from the top of the mantle to the bottom
|
|
We use Moh's hardness scale
What is the name of the scale that scientist use to classify the hardness of a mineral?
|
Forms from the remains of plants and animals
What is a organic sedimentary rock ?
|
- lithosphere
- astHenospere - mesosphere -outer core - inner core
What are the 5 physical layers of the Earth ?
|
In the subduction zone
Where does old oceanic crust go?
|
Unpleasant result in damage
What is deformation?
