|
o Fresh rock; straight from center of earth; comes form magma
o NO FOSSILS |
|
|
Sedimentary Rock
|
o Comes from igneous
• Weathered • Formed by little particles of igneous rock • Has fossils |
|
|
Metamorphic Rock
|
o Changed rock
• Sedimentary or igneous rock that is changed by plate movement and buried into magma |
|
|
Geologic Time
|
