Fossils: The Persevered Remains or Traces of Living Things
Sedimentary Rock: The type of rock that is made of hardened sediment
Mold: A fossil formed when an organism is buried in sediment, dissolves leaving a hollow area
Cast: A fossil that is a copy of an organism shape formed when minerals seep into mold
Petrified Fossil: A fossil in which mineral replace all or part of an organism
Carbon Film: A type of fossil consisting of an extremely thin coating of carbon rock
Trace Fossil :A type of fossil that provides evidence of the activities of ancient organisms
Paleontologist : A scientist who studies fossils to learn about organisms that have lived long ago
Scientific Theory : A well tested concept that explains a wide range of observation
Evolution : The process by which all the different kinds of living things that change over time
Extinct : Describes a type of organisms that no longer exist on earth
Relative Age : The age of rock layers
Absolute Age :The age of a rock given as the number of years since the rock formed
Law Of Superposition : The geologic principle that states that in horizontal layers a sedimentary rock, each layer is older that the layer above and younger than the layer
Extrusion : An igneous rock layer formed when lava forms onto earths surface
Intrusion : An igneous rock layer formed when magma hardens beneath earths surface
Fault : A break or crack in earths lithosphere along which rocks have
Uncomformaty : A place where an old, eroded rock surface is in contact with a near rock
Index Fossil : Fossil of widely distributed organisms that lived during only one short period
Radioactive Decay : The Breakdown of a radioactive element releasing particles and energy
Half Life : The length of time needed for half of the atoms of a sample of a radioactive isotope to decay
Geologic Time Scale :A record of the geologic events and life in earths scale
Era :One of the 3 long units of geologic time into which geologist divide eras.
Period : One of the units of geologic time into which geologists divide eras
Continental Drift : The gradual movement of the continents across the earths surface through geological time
Isotopes : An atom with the same number of protons and a different number of neutrons from other atoms of the same element
Mass Extinction : When many types of living things become extinct at the same time
Pursued Remains : Fossils
Radioactive Dating : The process of determining the age of an object using half of one or more radioactive isotopes
