ENVIORMENTAL SCIENCE REVIEW SHEET1)     Mutation- a random revision in one or more genes of organisms. Mutations may occur impromptu in nature, but exposure radiation and/or other chemicals immensely increase their number and degree. 2)     Natural selection- the process whereby the natural factors of environmental subway system tend to eliminate those members of the population that are least well fit to cope and thus, in effect select those best adapted for selection and reproduction.3)     Speciation-the evolutionary process whereby populations of a single species separate and, though cosmos exposed to different forces of natural selection, gradually develop into distinct species. 4)      discriminating pressure-An environmental factor that causes individuals with authoritative traits, which are not the norm for the population, to brave and reproduce more then rest of the population. The result is a alter in the genetic leadup of the population5)     Selective breeding- breeding of certain individuals because they bear certain traits and the exclusion from breeding of others. 6)     Tectonic plates- huge slabs of sways which make up the earths crust. 7)     Igneous jolt- produced under conditions involving intense warming "igneous rock is rock make by solidification from a molten conjure up especially from molten magma" "igneous fusion is fusion by heat alone.8)     Metamorphic rock- Pertaining to, produced by, or exhibiting, certain changes which minerals or rocks may have undergone since their pilot deposition -- especially applied to the recrystallization which sedimentary rocks have undergone through and through the persuade of heat and pressure, after which they are called metamorphic rocks.9)     Sedimentary rock- rock formed from consolidated cla y sediments10)     Aquifer- An underground bed or layer of earth, gravel, or porous stone that yields urine.11)     Capillary water- water that clings in small pores, cracks, and spaces against the leave out of gravity, like water held in a sponge. 12)     Aquitard- 13)     Condensation- collecting of molecules from the vapor arouse to form the liquid state, as for example, water vapor condenses on a cold surface to from water droplets. 14)     Desalinization- process that purify seawater into tall quality drinking water via distillation or micro-filtration.15)     Infiltration- the process that water soaks into the solid as oppose to running off the surface. 16)      Groundwater- water that has hoard in the ground completely filling and saturating all pores and spaces in rock and/or soil. Groundwater is free to move more of less readily. I t is the reservoir for springs and rise up and is replenished by infiltration of surface water. 17)      Percolation- the process of water seeping through cracks and pores in the sold or rock.
