rock - a naturally occurring solid mixture
of one or more minerals or organic matter
rock
cycle- the series of
processes in which a rock changes forms, changes from one type to another, is
destroyed, and forms again by geological processes.
erosion- the process by which wind, water,
ice, or gravity transports soil and sediment from one location to another.
deposition- the process in which material is
laid down
composition- the chemical makeup of a rock;
describes either the minerals or other materials in rock
foliated- the texture of metamorphic rock in
which the mineral grains are arranged in planes or bands
texture- the quality of a rock that is based
on the sizes, shapes, and positions of the rock’s grains
strata- layers of rock
nonfoliated
rock- the texture of
metamorphic rock in which the mineral grains are NOT arranged in planes or
bands
igneous
rock- forms when
hot, liquid rock (magma) cools and solidifies
sedimentary
rock- forms when
weathered rock is compressed and then cemented together
metamorphic
rock- created when
the structure, texture, or composition of a rock
changes due to heat, pressure,
or a combination of both
I'm looking forward to another great week at Ellis! See you Monday morning.
