Rock Cycle
|
the process in which rocks form, change, brake down, and reform
|
|
Crystallization
|
the process through which rocks form, either form molten rock or from coming out of solution
|
|
Plate Tectonics
|
the theory that Earth's surface, lithosphere, is divided into a series of segments which move
|
|
Atoms
|
the smallest unit of an element that has the properties of that element
|
|
Ions
|
atoms which have lost or gained electrons
|
|
Force
|
a push or pull
|
|
Newtons Three Laws
|
1. Inertia
2. F=ma 3. Action force/Reaction force |
|
Buoyancy
|
push back force equal to the force exerted by the amount of water displaced by the object
|
|
Gravity
|
The pull of an object towards the center of its mass
|
|
Topography
|
surface features of an area of Earth's continent (land)
|
|
Contour Lines
|
connect points of equal elevation
|
|
Rules for a contour map
|
1. contour lines never cross
2. circles show highest (hill, mountains) and lowest (basins, lakes) in a closed system 3. hachurre lines show decreases in elevation in a depression 4. contour lines crossing a stream point toward higher elevation. 5. The closer the lines the steeper the slope 6. The index lines have numbers on them 7. on a map the contour intervals are always the same |
|
Science Process Skills
|
set of "steps" through which information is gained and verified, including observations, hypothesis, variables, writing procedures, organized data
|
|
Observation
|
information gained using the five senses
|
|
Hypothesis
|
proposed solution to a problem to be tested; based on observations and previous experience
|
|
Variables
|
anything which can change in an experiment
|
|
Independent Variable
|
the one variable which is deliberately changed from one trial to another by the experimenter
|
|
Dependent
|
the variable which may change in response to changes in the independent variable
|
|
Controlled (constant) Variables
|
the variables which must remain the same from one trial to another
|
|
Procedure
|
Step by step sequence for conducting an experiment
|
|
data
|
observations of the changes made due to the manipulation of one variable; they are usually recorded in an organized chart
|
|
quantitative
|
observations involving measurements
|
|
qualitative
|
observations of what occurs; very descriptive
|
|

1. surface mining
2. open-pit mining 3. deep mining 4. strip mining |
|
Density
|
amount of mass in a given volume of space ( written as g/ml)
|
|
Four Spheres of Earth
|
1. Atmosphere
2. Hydrosphere 3. Geosphere 4. Biosphere |
|
Weight
|
The pull of gravity on the mass of an object
