Evidence
a naturally occurring solid that can form by inorganic processes
a mineral
What are the three rock types?
sedimentary
igneous
metamorphic
series of processes that occur on Earth's surface and the crust and mantle that change rocks from one type to another
Rock Cycle
There is more ________________ and _____________ the deeper you go into Earth's Interior.
Heat and Pressure

4
the five characteristics of a mineral
naturally occurring
solid
formed by inorganic process
crystal structure
chemical composition
formed from cooled lava or magma
igeneous
Trees and animals and weather can break rocks down into smaller pieces
weathering
Heat from the core and the mantle carry hot solid rock inside Earth's interior in a never ending cycle
Convection Currents
The __________________ is a dense ball of solid nickel and iron.
Inner Core
a repeating pattern that represents over and over again
crystal
formed from compaction and cementation
sedimentary

4
True or False: both diamonds and graphite are formed from carbon.
True
True or False: the mantle is liquid magma under the Earth's crust.
False
how light reflects from a minerals surface
luster
was a different type of rock before heat and pressure affected it
metamorphic
