Igneous Rock
rock made from magma that has cooled and hardened
None
Sedimentary Rock
rock that forms from sediment and other rock particles that have settled in layers
Metamorphic Rock
rock that forms from heat and pressure
Lava
Magma that has reached the Earth's surface and has cooled and hardened
Magma
Hot, melted rock that is inside a volcano
Mineral
a NONLIVING solid found in nature
Sediments
tiny pieces of rock material carried by water
Volcano
an opening through which magma escapes to the earth's surface
core
the inner layer that forms the center of the earth
mantle
the thick layer that forms the center of the earth
crust
the outer layer of the earth
rock
hard and made of minerals
rock cycle
rocks changing from one type to another
the 3 properties of minerals
shape, color, and hardness
Where do magmas originate?
Originate in the mantle
Characteristics of Intrusive rocks
1) cooling happens deep underground 2) slow cooling 3) texture is coarse grained
None
Characteristics of Extrusive rocks
1) cooling happens near surface 2) Cool rapidly 3) texture is fine grained
None
glassy texture
- no grains, - rapid cooling rate, - commonly black in color
None
Ferromagnesian
- more Fe and Mg present, -- darker in color Examples: gabbro, basalt
None
Non-Ferromagnesian
- less Fe and Mg present, -- more silica is present, -- lighter in color, Examples: granite, rhyolite
None
What is Magmatic differentiation?
how magmas change composition to form different igneous rock types
What ways does magmatic differentiation occur?
1) Crystalization - cools and crystalizes 2) Assimilization - melts and combines with other rock 3) mixes with other magma
None
