|
By adding or taking away heat
|
|
Tell what you know about ions:
|
If an atom lost an electron, then it is a positive ion with a charge of +1. If an atom gains one electron than it is an negative ion with a charge of -1
|
|
What is the difference between an element, a compound, and a mixture?
|
-an element cannot be separated into simpler substances by ordinary chemical meants (there are 109 elements)
-A compound is any combination of two or more different kind of atoms (like water which is hydrogen & oxygen) -a mixture is two or more substances PHYSICALLY combined (ex: soil) |

How can you identify a mineral?
|

|
|
What is the difference between a metal and nonmetal?
|
There are 4 special properties that metal has:
-shiny surface -conduct electriciy and heat. -malleability (the ability to be hammered into thin sheets without breaking) -ductility (the ability to be pulled into thin strands without breaking) |
|
What are the 3 classifications of rocks?
|
Sedimentary
Igneous Metamorphic |
|
How does an igneous rock form?
|
when magma from deep in the earth cools and hardens
|
|
How does sedimentary rock form?
|
formed when small pieces of rocks, shells, animals, etc. settle to the bottom of the ocean and are pressed and cemented together
|
|
How does metamorphic rock form?
|
Metamorphic rocks form when rocks experience great heat, pressure and chemical reactions.
|
|
What is the difference between intrusive and extrusive igneous rocks?
|
igneious rocks formed deep within the earth are Intrusive (In the earth)
-Igneious rocks fromed from lava at the surface are extrusive |
|
Know the rock cycle
|
Pg. 170 of Prentice Hall Earth Science book (STUDY NOW!)
|
|
Look at Rock lab
|
You will have to be able to identify some of those rocks (STUDY NOW)
|
|
What is metamorphism?
|
The changing of one type of rock into another as a result of tremendous heat, pressure and chemical reactions.
|
|
What are the two types of metamorphism?
|
-contact metamorphism (when rocks are heated by contact with magma or lava)
-regional metamorphism (when a large are of rock deep within the earth's surface is changed by increase of temperature and pressure) |
|
What metamorphic rock does sedimentary rock Shale become?
|
slate
|
|
What metamorphic rock does igneous rock granite become?
|
gneiss
|
|
What metamorphic rock does sedimentary rock sandstone become?
|
quartzite
|
|
Which metamorphic rock does sedimentary rock limestone change to?
|
marble
|
|
Know the igneous rock table:
|
(STUDY STUDY SHEET NOW) - (you know the charts are always on the test :)
|
|
What is foliated rock and give some examples:
|
Foliated rocks have mineral crystals arranged in parallel layers or bands. They tend to break along these bands ex: SLATE, GNEISS
|
|
What is unfoliated texture rock and give an example:
|
An untoliated rock does not have bands of crystals and do not break in layers. ex: QUARTZITE, MARBLE
|
|
How are sedimentary rocks classified? Igneous?
|
-sedimentary - composition, texture, grain size
-igneous - texture and chemical composition |
|
Facts on sedimentary rocks
|
75% of all rocks are sedimentary, the three types are clastic rock, organic rock, and chemical rock.
|
|
What is clastic rock (type of sedimentary rock)?
|
Rocks made by broken pieces of rock joined together.
|
|
What are organic rocks (type of sedimentary rock)?
|
Organic rocks are rocks formed by material that was once living.
|
|
What is chemical rock (type of sedimentary rock)?
|
Chemical rock is rock formed when water evaporates and leaves behind mineral deposits (this rock is called evaporites). Rock salt is an example.
