|
physical properties of matter |
can be observed without changing composition of the substance ex: color, smell, freezing point, boiling point, melting point, density |
|
|
chemical properties of matter |
how substance reacts with other substances ex: heat of combustion, reactivity with water, PH |
|
|
Igneous rock |
-forms from cooled magma -volcanic activity -crystalline |
|
|
intrusive igneous rock |
-magma cools deep inside crust -cools slowly -coarse-grained (large crystals) |
|
|
extrusive igneous rock |
-lava cools at earth's crust -cools quickly -fine-grained (small crystals) |
|
|
sedimentary rock |
-sediment deposits are compressed,cemented together, and hardened (compaction/cementation) -stratification: layering |
|
|
metamorphic rock |
-"changed form -extreme heat and pressure cause rock to change |
|
|
Rock Cycle |
-Igneous to Sedimentary: igneous rock is exposed at Earth's surface and is broken down into sediment. sediment is compacted -Sedimentary to Metamorphic: rock changes temp & pressure - Metamorphic to Igneous: melts and becomes magma. magma cools |
|
|
Mineral Properties |
inorganic (nonliving), naturally occurring, solid, crystalline form, consistent chemical composition |
|
|
Physical properties of minerals |
color, streak, luster, cleavage, fracture, hardness, density |
|
|
streak |
color of mineral in powdered form |
|
|
cleavage |
mineral split along planes of weakness to form flat surfaces |
|
|
fracture |
mineral breaks unevenly into pieces that have curved irregular surfaces |
|
|
hardness |
measure of ability of a mineral to resist scratching *mineral with lower number will be scripted by mineral with higher number* |
|
|
density |
ratio of mass to volume |
|
|
luster |
way light interacts with surface
metallic or non metallic |
|
|
conflict minerals |
-mined in Congo -controlled by militia groups -unsafe working conditions, child militia, rape |
