THE GEOLOGIC TIME SCALE IS LIKE THIS FOR GEOLOGISTS
WHAT IS A CALENDAR?
ERAS ARE DIVIDED INTO THESE
WHAT IS A PERIOD?
THIS ERA IS MISSING: PRECAMBRIAN, PALEOZOIC, CENOZOIC
WHAT IS MESOZOIC?
THE PERIOD OF TIME WE LIVE IN
WHAT IS THE QUATERNARY PERIOD?
THERE ARE THIS MANY PERIODS OF TIME
WHAT IS ELEVEN?
REMAINS OF ORGANISMS ARE DRYED OUT BY THIS FOSSILIZATION PROCESS
WHAT IS MUMMIFICATION?
HARDENED TREE SAP IS THIS WHICH FOSSILIZES ORGANISMS CAUGHT IN IT
WHAT IS AMBER?
DAILY DOUBLE!!!!!!!! FOOTPRINTS ARE AN EXAMPLE OF THESE
WHAT ARE TRACE FOSSILS?
THESE FOSSILS CAN BE USED TO STUDY THE EATING HABITS OF ANCIENT ANIMALS
WHAT ARE COPROLITES?
ORGANISMS WHO LIVED A BRIEF PERIOD OF TIME AND LEFT THEIR FOSSILS IN SEDIMENTARY LAYERS
WHAT ARE INDEX FOSSILS?
MOLDS FILLED WITH SEDIMENTS
WHAT ARE CASTS?
STONES SOME DINOSAURS HAD IN THEIR DIGESTIVE SYSTEMS
WHAT ARE GASTROLITHS?
TAR PITS THAT FOSSILIZE ANIMALS ARE MADE OF THIS.
WHAT IS PETROLEUM?
A FOSSILIZED WING OF AN INSECT IS AN EXAMPLE OF THIS.
WHAT IS A TRACE FOSSIL?
THIS RETAINS THE SHAPE AND SURFACE MARKINGS OF THE ORIGINAL ORGANISM.
WHAT IS A MOLD?
THESE SCIENTISTS STUDY FOSSILS TO LEARN ABOUT EARTHS PAST.
WHO ARE PALEONTOLOGISTS?
HE IS RESPONSIBLE FOR THE THEORY OF NATURAL SELECTION.
WHO IS CHARLES DARWIN?
SCIENTISTS WHO STUDY GEOLOGY
WHO ARE GEOLOGISTS?
JAMES HUTTON WAS A SCIENTIST WHO STUDIED THE SHORES OF SCOTLAND AND DISCOVERED THIS ABOUT THE EARTH.
WHAT IS VERY OLD?
SCIENTISTS USE RADIOMETRIC DATING TO DETERMINE THIS KIND OF AGE OF ROCK.
WHAT IS ABSOLUTE AGE?
SEDIMENTARY ROCK LAYERS OLDER THAN THE LAYERS ABOVE IT AND YOUNGER THAN THE LAYERS BELOW IT IS DUE TO THIS LAW.
WHAT IS THE LAW OF SUPERPOSITION?
SEDIMENTS DEPOSITED IN LAYERS FORM THIS KIND OF ROCK.
WHAT IS SEDIMENTARY?
SOMETIMES ROCK LAYERS GET OVERTURNED OR FOLDED DUE TO THESE STRONG EARTH FORCES.
WHAT IS TECTONIC ACTIVITY?
IN LAYERS OF UNDISTURBED ROCK, THE OLDEST SEDIMENTARY ROCKS ARE HERE.
WHAT IS THE BOTTOM?
ROCK LAYERS ARE DISTINGUISHED FROM EACH OTHER BY THESE THAT THEY CONTAIN.
WHAT ARE INDEX FOSSILS?
The History of Earth.
A Little Bit of History… The history of geologic time begins with the human interest in mining. Interests in rock units began to flourish with commercial.
Chapter 12. Warm-up9/1/15 List and briefly describe three different types of fossils.
Uniformitarianism: the processes that act on the Earth’s surface today are the same as the processes that have acted on the Earth’s surface in the past.
The Rock and Fossil Record. Uniformitarianism - proposed by James Hutton - states that Earths landscape is constantly changing due to the same geologic.
Geologic Time. The Geologic Time Scale A summary of major events in Earth’s past that are preserved in the rock record Divisions of Geologic Time.
Rock Record Spring 2013.
How do scientists know that different kinds of plants & animals lived in the past?
The Fossil Record. 1. Fossils are the remains of organisms that lived in a previous geologic time. 2. The study of these fossils is called paleontology.
The Rock Record Chapter 8 The earth is approximately 4.6 billion years old.
