Rock Cycle
|
The process in which rocks form, change, break down, and reform.
|
|
Crystallization
|
The process through which rocks form, either from 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
|
|
Newton's Three Laws
|
1. Inertia
2. F=MA 3. Action force, Reaction force |
|
Buoyancy
|
A 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 are of Earth's continent.
|
|
Contour Lines
|
Connect points of equal elevation.
|
|
Rules for a Contour Map
|
1. Lines never cross
2. circles show highest and lowest points 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. index lines have numbers on them. 7. On a map, the contour intervals are always equal. |
|
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
|
The proposed solution to a problem to be tested based on observations and prior knowledge.
|
|
Variables
|
Anything which can change in an experiment.
|
|
Independent Variable
|
The one variable which is deliberately changed by the experimenter.
|
|
Dependent Variable
|
The variable which may change in response to changes in the independent variable.
|
|
Controlled Variables
|
Those 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
|
Observations involving measurements.
|
|
Qualitative Observations
|
Observations of what occurs; very descriptive.

|
|
Four Spheres of Earth
|
1. Atmosphere
2. Hydrosphere 3. Geosphere 4. Biosphere |
|
Weight
|
The pull of gravity on the mass of an object.
