Eon: Half a billion years or more. Era: Several 100 million years. Geologic Time Vocabulary Set-up Directions: Tape this directions page and the vocabulary list in your Lab Journal. 3 Hole Punch your vocabulary Learning Vocabulary Directions: Column 1 – Write in the definitions. Column 2 – Create a colored illustration for the word or phrase or find one on the internet, print and colorize it. Column 3 – Use the word or term in a sentence. You may choose to: Create your own sentence. Find the word used in a sentence in your textbook and note the page #. Google the word or phrase, copy the word used in a sentence, and include the site title or address. Quality Check: Use CUPS to ensure you have created grammatically correct sentences. 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. Radiometric testing = a method of dating geological or archeological specimens by determining the relative proportions of particular radioactive isotopes present in a sample. stratigraphy = The study of rock layers (strata), especially the distribution, deposition, and age of sedimentary rocks. era = a long and distinct period of history with a particular feature or characteristic; several hundred million years period = subdivision of an era epoch = subdivision of a period 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. fossil = the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock. exoskeleton = external skeleton endoskeleton = internal skeleton 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. cyanobacteria = blue-green algae a group of photosynthetic bacteria which release oxygen into the atmosphere 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. 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. extinction = the state or process of a species becoming extinct, no longer existing on the Earth. Pangea = a continent which included all the landmass of the earth prior to the Triassic period gymnosperm = a plant, such as a pinetree, whose seeds are not enclosed within an ovary, fruit. angiosperms = a plant having its seeds enclosed in an ovary; a flowering plant. 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. 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 100 million years. Epoch: 10’s of millions of years. Age: millions of years.
