|
The application of logic and reason to observations and conclusions.
|
What is Critical Thinking? (12)
|
Using your existing knowledge to solve problems through observing, gathering information and making logical adjustments based on previous information and that you have gathered.
|
|
|
The outermost and thinnest layer of Earth. It can be divided into two compositional layers: Oceanic & Continental. (558)
|
What is the Crust?
|
This layer is generally cool, made of hard, solid rock, and varies in thickness from 2.5-4.3 miles (oceanic) to 12-25 miles (continental)
|
|
|
The rate that electric charges move through a conductor.
|
What is Current? (439)
|
This can be Direct_?__ where electric charges move from one terminal to another in the same direction or Indirect where charges can move to terminals alternately.
|
|
|
A reaction in which one compound breaks into at least two products.
|
What is a Decomposition Reaction? (155)
|
A reaction that breaks substances apart.
AB yields A + B; Ex.2H2O yields 2H2 + O2 or Electrolysis of water breaks down into hydrogen gas & oxygen gas when electric current flows through water. |
|
|
The mass per unit volume of a substance.
|
What is Density? (55)
|
D = m/V ; D = mass divided by volume.
also comparisons of substances as light or heavy; will it float/sink, rise in air/ remain on earth. |
|
|
The process by which sediment is laid down.
|
What is Deposition? (586)
|
The sediment is dropped out/deposited as rivers slow down when entering a lake, gulf, bay, sea or ocean.
|
|
|
Any interference in which waves combine so that the resulting wave is smaller that the largest of the original waves.
|
What is Destructive Interference? (377)
|
In wave interaction, when the crest of one wave meets the trough of another wave, the resulting wave has a smaller amplitude than the larger of the two waves. If two waves have equal amplitude they may cancel each other out with this type interaction.
|
|
|
A nonsoap water-soluble cleaner that can emulsify dirt and oil.
|
What is Detergent? (208)
|
Varies from soap as the charged end of a detergent is a sulfonate group (-SO3) not a carboxylate group (-COO-) ; also differ from soaps because their chains are derived from petroleum products instead of compounds found in animal fats.
|
|
|
The temperature at which water vapor molecules start to form liquid water.
|
What is the Dew Point? (608)
|
Depends on humidity. If high the droplets form more easily. Ex. the drops of water, condensation, that forms on a cold glass of ice water.
The cold surface of glass provides a place wher this critical temperature is reached and water shifts from gas to liquid. |
|
|
The bending of a wave as it passes an edge or an opening.
|
What is Diffraction? (375)
|
Ex. waves passing around a block in a tank of water. Waves bend around the edge of the block and spread ou into the space behind the block.
|
|
|
A substance that donates protons, H+ , to form hydronium ions, H3O+, when dissolved in water.
|
What is an Acid? (199)
|
Properties: sour taste, can burn skin/eyes, turns blue litmus paper red & can conduct electricity. Ex. Hydrocloric (muriatic) cleaning, pool chemical; Nitric / fertilizer/TNT; Formic/ dyeing textile; Citric / soft drinks, candles, & flavorings
|
|
|
Any precipitation that has an unusually high concentration of sulfuric or nitric acids resulting from chemical pollution of the air.
|
What is Acid Rain? (585)
|
Causes damage to both living organisms and inorganic matter; Chemical Weathering.
|
|
|
A weak base that neutralizes excess stomach acid.
|
What is an Antacid? (210)
|
Ex. sodium hydrogen carbonate and magnesium hydroxide (milk of magnesia); Nexium or Prilosec.
|
|
|
A substance that either contains hydroxide ions, OH-, or reacts with water to form hydroxide ions.
|
What is a Base? (201)
|
Properties: Slippery, bitter, can conduct electricity, turns red litmus paper to blue, burns skin in concentrated form
|
|
|
A basic solution that can either can either be used as a disinfectant or th remove colors and stains.
|
What is Bleach. (209)
|
A solution of sodum chlorite, NaOCl, and water; it removes the color of unwanted stain by oxidizing the component responsible.
|
