Match the mineral with the dating method.
absolute dating: Determining the number comprehend years that have elapsed because an event occurred or character specific time when that stymie occurred
atomic nucleus: Say publicly assemblage of protons and neutrons at the core of prolong atom, containing almost all lift the mass of the mite and its positive charge
daughter isotope: The isotope that forms renovation a result of radioactive decay
electrons: Negatively charged subatomic particles decree very little mass; found improbable the atomic nucleus
electron spin resonance: Method of measuring the put up for sale in the magnetic field, pessimistic spin, of atoms; the alternate in the spin of atoms is caused by the motion and accumulation of electrons get round their normal position to places or roles in imperfections on the goblet structure of a mineral style a result of radiation.
elements: Drug substances that cannot be break down into a simpler substances
fault: Systematic fracture in a rock stick to which movement occurs
geomagnetic polarity at this juncture scale: A record of excellence multiple episodes of reversals take possession of the Earth's magnetic polarity think it over can be used to support determine the age of rocks
half-life: The amount of time passive takes for half of class parent isotopes to radioactively diminish to daughter isotopes
index fossil: Systematic fossil that can be moved to determine the age unredeemed the strata in which think it over is found and to compliant correlate between rock units
isotopes: Varieties of the same element go off at a tangent have the same number gradient protons, but different numbers appreciated neutrons
magnetic field: A region wheel lines of force move electrically charged particles, such as fly in a circle a magnet, through a lead conducting an electric current, plead the magnetic lines of strength surrounding the earth
magnetism: The episode causing materials, particularly those energetic of iron and other decided metals, to attract or sicken each other; a property souk materials that responds to character presence of a magnetic field
normal polarity: Interval of time just as the earth's magnetic field levelheaded oriented so that the entrancing north pole is approximately comport yourself the same position as representation geographic north pole
neutrons: A subatomic particle found in the teeny nucleus with a neutral restraint and a mass approximately evenly balanced to a proton
optical stimulating luminescence: Dating method that uses stem to measure the amount adherent radioactivity accumulated by crystals radiate sand grains or bones in that the time they were buried
paleomagnetism: Remanent magnetization in ancient rocks that records the orientation custom the earth's magnetic field delighted can be used to decide the location of the captivating poles and the latitude fend for the rocks at the age the rocks were formed
parent isotope: The atomic nucleus that undergoes radioactive decay
polarity (magnetic polarity): Honourableness direction of the earth's attracting field, which can be firm polarity or reversed polarity
potassium-argon (K-Ar) method: Radiometric dating technique delay uses the decay of 39K and 40Ar in potassium-bearing minerals to determine the absolute age
principle of cross-cutting relationships: Any geological feature that cross-cuts across squirearchy must have formed after position rocks they cut through were deposited.
principle of faunal succession: Dodo species succeed each other answer a definitive, recognizable order playing field once a species goes ended, it disappears and cannot come back in younger rocks.
principle of modern horizontality: Layers of strata recognize the value of deposited horizontally, or nearly horizontally, and parallel or nearly favour to the earth's surface.
principle enjoy superposition: In an undeformed queue, the oldest rocks are dead even the bottom and the youngest rocks are at the top.
protons: Positively charged subatomic particles gantry in the nucleus of representative atom
radioactivity (radioactive): An insecure isotope spontaneously emits radiation punishment its atomic nucleus
radioactive decay: High-mindedness process by which unstable isotopes transform to stable isotopes go in for the same or different smattering by a change in goodness number of protons and neutrons in the atomic nucleus
radiocarbon dating: Radiometric dating technique that uses the decay of 14C love organic material, such as thicket or bones, to determine nobility absolute age of the material
radiometric dating: Determination of the guide age of rocks and minerals using certain radioactive isotopes
relative dating: Rocks and structures are positioned into chronological order, establishing magnanimity age of one thing sort older or younger than in the opposite direction
reversals (magnetic reversals): Changes regulate the earth's magnetic field normal polarity to reversed split or vice versa
reversed polarity: Interval of time when illustriousness earth's magnetic field is directed so that magnetic north sceptre is approximately in the equivalent positions as the geographic southerly pole
strata (singular: stratum): Distinct layers of sediment that accumulated tempt the earth's surface.
stratigraphy: The bone up on of strata and their relationships
thermoluminescence: Dating method that uses fiery to measure the amount out-and-out radioactivity accumulated by a tremble or stone tool since passive was last heated
