Term Definition
Abiotic Non living object
Acid On pH scale, 0-6, 0 being the most acidic. Has many hydrogen ions.
Adaptation adjustment to environmental conditions
alkaline it is anything basic on the pH scale not acidic
aquatic growing or living in or frequenting water
base many hydroxide ions OH, 14 being the most basic and 8 being the least. could also be begining and starting point for topgraphy .
biotic living organisms
buffer a substance capable in solution of neutralizing both acids and bases and thereby maintaining the original acidity or basicity of the solution
cementation the process in which dissolved minerals crystallize and glue themselves back together
chemical rock secimentary rock that forms when minerals crystallize from a solution
chemical weathering process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents.
chlorine substance that destroys many animals and plants and can be found in places from rivers to pools
clastic rock sedimentary rock that forms when rock fragments are squeezed together
cleavage mineral that splits easily along flat surfaces and has ice skating rink flat appearance
compaction the process that pushed sediments together
contour interval space between contour lines
contour lines the lines marking the elevation on a topography map
control the group of an experiment that has not been changed nor altered for the experiment. the norm
crystal repeating pattern of a mineral's particles forms a solid
crystal system any of the seven groups (cubic, hexagonal, rhombohedral, tetragonal, orthorhombic, monoclinic, and triclinic) of crystals
crystallization the process in by which atoms are arranged to form a material with a crystal structure
decomposition reduction of the body of a formerly living organism into simpler forms of matter.
degradation weakening chemicals...i think
density m/v...measuring how dense something is, mass of a unit volume of a material substance,
dependent variable a variable that depends on other factors.
detritus loose material (as rock fragments or organic particles) that results directly from disintegration
dichotomous key a key used to decipher something with yes or no questions
diversity index value statistic which is intended to measure the biodiversity of an ecosystem
electronic balance a electronic tool used to measure mass
elevation how high or low an area is from sea level
erosion running water, wind or ice loosen and carry away rock fragments
extursive rock an igneous rock formed from lava that erupted onto earth's surface
foliation metamorphic rocks that have their grains arranged in parralel layers or bands
fracture how a mineral looks when it breaks apart in an irregular way
gemstone hard, colorful mineralthat has a brilliant or glassy luster
graduated cylinder a measuring device that measures the volume of an object for water displacement or measures the how much water is in the cylinder etc.

pinkyrocks45 : thank u soo much
indiagurl011 : thanks!
indiagurl011 : oh and i changed the definition of crystal system (it hink . . . it's not showing up here, don't know why)
indiagurl011 : kk not showing up but heres the def.: any of the seven groups (cubic, hexagonal, rhombohedral, tetragonal, orthorhombic, monoclinic, and triclinic) of crystals
maevexolentricchia : thanks!
jaybyrd : what about centimeter??
jaybyrd : i know that's pretty obvious, but i guess since its one of the words...
jaybyrd : def: 1 100th of a meter
bazookabubble52 : im gonna keep adding words each night....so keep checking :)
indiagurl011 : hey um
indiagurl011 : the definition of alkaline is wrong
indiagurl011 : it is anything basic on the pH scale not acidic
kateisthegr844 : um...amanda.... can we get married? ahahhahaa i love u hahah u like saved my fricken life hahah this is awesome u r amazing I LOVE U AND UR WONDERFUL SCIENCE WORDS HAhahaha a
bazookabubble52 : dita..im changing the definition 4 u :)
