The atmosphere traps solar radiation, because of gases such as CO2, methane and water vapor.
More harmful UV rays hit earth due to a gradual decrease of the layer of ozone (upper atmosphere); caused by products using chlorofluorcarbons or cfc's.
Rivers of hot or cold water within the ocean caused by planet rotation, wind, temperature and salinity.
Substances moving from areas of greater concentration to areas of less concentration until equilibrium is reached. (examples: heat moves from warmer to cooler areas; gases, nutrients, water moves across a semipermeable membrane)
Genetic trait that is represented with a capital letter and will always show if it is present.
The measure of an element's ability to combine with other elements, dictated by the number of electrons in the outermost shell.
Evidence of a new substance; observed when substances interact such as flammability and rusting.
What you can observe without the material changing to a new substance (melting, freezing, getting smaller)
One or more elements in the same place at the same time, but not chemically combined (like a tossed salad).
Energy that is stored (stress in a fault zone, roller coaster at the top of a hill).
Molecules expand as more energy is added (alcohol goes up the thermometer showing temperature as heat is added).
The distance an object travels divided by the time it takes to travel that distance.
The total amount of force acting on an object (all the individual forces are added together).
The change in an objects speed and/or direction; speeding up slowing down, or change in direction.
The shape of the Earth's surface and the way its physical features are arranged; positions and elevations.
F = M X A; If an object is acted on by a net force, the change in velocity will be in the direction of the force.
Newton's 2nd Law of Motion
An object at rest will remain at rest unless acted upon by an unbalanced force; an object moving at a constant velocity will remain in the same motion unless acted upon by an unbalanced force.
Newton's 1st Law of Motion
(also known as the manipulated variable) the variable that you change during an experiment.
(also known as the responding variable) the variable that you expect to change as a response to the manipulated variable.
