Exploring Creation with Physical Science (Dr. Wile)

This is the vocab from Exploring Creations w/ Physical Science (Dr. Jay L. Wile) I'll be adding new words every week or two as I go on in the class. Please let me know if I mis-spelled anything!!
The smallest stable unit of matter in Creation.
A group of two or more atoms linked together to form a unique substance.
The quantity of a substance within a certain volume of space.
The moisture content in the air.
Absolute Humidity
The mass of water vapor contained in a certain volume of air.
Relative Humidity
A quantity expressing humidity as a percentage of the maximum absolute humidity for that particular temperature.
Greenhouse Effect
The process by which certain gases (principally water vapor, carbon dioxide, and methane) trap heat that would otherwise escape the earth and radiate into space.
Parts Per Million
The number of molecules (or atoms) of a substance in a mixture for every one million molecules (or atoms) in that mixture.
The mass of air surrounding a planet.
Atmospheric Pressure
The pressure exerted by the atmosphere on all objects within it.
an instrument used to measure atmospheric pressure
The lower layer of earth's atmosphere, which exists from ground level to roughly 80 kilometers (50 miles) above sea level
The upper layer of earth's atmosphere, which exists higher than roughly 80 kilometers (50 miles) above sea level
The region of the atmosphere that extends from ground level to roughly 11 km (7 mi.) above sea level.
The region of the atmosphere that spans altitudes of 11 km (7 mi.) to 48 km (30 mi.)
The regoin of the atmosphere that spans altitudes of 48 km (30 mi.) to 80 km (50 mi.)
Jet Streams
Narrow bands of high-speed winds that circle the earth, blowing from west to east.
Energy that is being transfered.
A measure of the energy of motion in a substance's molecules.
The region of the atmosphere between altitudes of roughly 80 km and 460 km
The region of the atmosphere above an altitude of 460 kilometers
The region of the atmosphere between the altitudes of 65 km and 330 km where the gases are ionized.
Using electricity to breake a molecule into its constituent elements
Polar Molecule
A molecule that has slight negative and positive charges due to an imbalance in the way electrons are shared
A liquid substance capable of dissolving other substances
A substance that is dissolved in a solvent
The phenomenon that occurs when individual molecules are so strongly attracted to each other that they tend to stay together
Hard Water
Water that has dissolved ions in it, predominately calcium ions
The mass of water on a planet
Hydrologic Cycle
The process by which water is continuously exchanged between earth's various water systems
Emission of water vapor from plants
The process by which water vapor turns into a liquid
Water falling from the atmosphere as rain, snow, sleet, or hail
Evaporation and condensation of a mixture to seperate out the mixture's individual components
Residene Time
The average time a water molecule will stay in a given water source
A measure of the quantity of dissolved salt in water
A dense, icy pack of snow
Water Table
The imaginary line between the water saturated soil and the soil not saturated with water
The process by which water passes from above the wter table to below it
Adiabatic Cooling
The cooling of a gas that happens when gas expands
Cloud Condensation Nuclei
Small particals that water vapor condenses on to form clouds
