1. Project # __: Geologic Time Vocabulary Due: _________________ Directions: Tape this directions page and the vocabulary list in in your Lab Journal. Use the directions below as a rubric to complete your project: ____ 1 pt. /wordCopy the words on your project pages. ____ 1 pt./ word Copy the definitions on your project pages. ____ 1 pt./ wordCreate a drawing to illustrate the word. ____ 1 pt. / wordColor the drawing. ____ 1 pt. / wordUse the word in a sentence. 5 points total/ word = 100 points for the total project. There will be a vocabulary test over these words after the project is due! 1.geologic time scale = is a system of chronological measurement that relates stratigraphy to time, and is used to describe the timing and relationships between events that have occurred throughout Earth’s history. 2.Radiometric testing = a method of dating geological or archeological specimens by determining the relative proportions of particular radioactive isotopes present in a sample. 3.stratigraphy = The study of rock layers (strata), especially the distribution, deposition, and age of sedimentary rocks. 4.era = a long and distinct period of history with a particular feature or characteristic; several hundred million years 5.period = subdivision of an era 6.epoch = subdivision of a period 7.trilobite = extinct marine arthropod that occurred abundantly during the Paleozoic era, with a carapace over the forepart, and a segmented hind part divided longitudinally into three lobes. 8.fossil = the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock. 9.exoskeleton = external skeleton 10.endoskeleton = internal skeleton 11.plate tectonics = a theory explaining the structure of the earth's crust and many associated phenomena resulting from lithospheric plates that move over the underlying mantle. 12.cyanobacteria = blue-green algae a group of photosynthetic bacteria which release oxygen into the atmosphere 13.amphibians = a cold-blooded vertebrate animal that has an aquatic gill- breathing larval stage followed by a terrestrial lung-breathing adult stage. Egg layers in water. 14.reptiles = a cold-blooded vertebrate of a class that includes snakes, lizards, crocodiles, turtles, and tortoises. They are distinguished by having a dry scaly skin, and typically laying soft-shelled eggs on land. 15.extinction = the state or process of a species becoming extinct, no longer existing on the Earth. 16.Pangea = a continent which included all the landmass of the earth prior to the Triassic period 17.gymnosperm = a plant, such as a pinetree, whose seeds are not enclosed within an ovary, fruit. 18.angiosperms = a plant having its seeds enclosed in an ovary; a flowering plant. 19.mammal = a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and the birth of live young. 20.marsupial = a mammal of an order whose members are born incompletely developed and are typically carried and suckled in a pouch on the mother's belly. Eon: Half a billion years or more. Era: Several hundred million years. Epoch: Tens of millions of years. Age: Millions of years.
