Rocks & Rock Cycle Flashcards
any naturally occurring solid mass or aggregate of minerals or mineraloid matter
rock
3 classifications of rocks
igneous, sedimentary, metamorphic
mappable unit of rock consisting of an initially connected volume deposited in one interval of time
rock formation
getting material into deeper depths
burial
the process of bringing material buried under the surface onto the surface
uplift
formed by weathering of rocks
soil
explain the rock cycle
nag-explain
process involved in breaking down rocks and transferring to another place until it settles in a place
Weathering, erosion, transportation, and deposition
come from sediments which may come from any kind of rock
sedimentary rocks
come from magma
igneous rocks
come from any kind of rock as long as they are buried deep enough to experience great temperature and pressure
metamorphic rocks
naturally occurring inorganic compound with a definite composition
minerals
7 mineral properties
color
streak
luster
hardness
cleavage
fracture
density
color
color
color of mineral in its powdered form
streak
the way the mineral reflects light
luster
4 common types of luster
metallic
dull
pearly
vitreous (glassy)
measures the ability to scratch or be scratched
hardness
used to determine how hard a mineral is
Mohs Scale of Hardness
The way a mineral breaks along a plane easily and smoothly based on its lattice. The plane of breakage
cleavage
The way a mineral breaks if there are no cleavage planes.
fracture
Mass/Volume of a mineral. Specific weight (Weight/Volume) is simply the density multiplied by g
density
fast cooling of magma
no time to become ordered
small crystals
slow cooling of magma
higher level of ordering
larger crystals
rapid cooling of magma
glassy rock
no crystals
other processes that form minerals
Precipitation from aqueous solution or gaseous emanations
Metamorphism
Weathering
Organically
