Earth is about 4.5 billion years old. In order to characterize the events that happened in this very long time scale, scientists have developed the geologic time scale. Here, the age of Earth is divided into (1), which in turn divided into (2), and are further subdivided into (3). The geologic time scale is so-called since the different subdivisions are based on the fossil record.

It has been suggested that the current time should be made into a different period. In other words, it should not have been part of the Holocene period due to the extreme changes man has made to the earth. If you were a scientist tasked to give a name to the period of today what name would you give it and why?
Scientists are examining the possible role of a large asteroid in the cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and the diffusion of sunlight. which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike?
Which of the following geologic periods is not part of the Paleozoic Era? the Carboniferous Period the Cambrian Period the Cretaceous Period the Devonian Period the Ordovician Period
Geological time covers huge spans, up to billions of years. Yet humans rarely live for more than 100 years. Therefore, why should we bother trying to understand geological time? Does this topic have any relevance to society?
A paleontologist estimates that when a particular rock formed, it contained 12 mg of the radioactive isotope potassium-40. The rock now contains 3 mg of potassium-40. The half-life of potassium-40 is 1.3 billion years. From this information, you can conclude that the rock is approximately ______________ billion years old.
The “age of fishes”, which began with the Cambrian Period (about 541 million years ago), and ended with the Permian/Triassic extinction event (about 252 million years ago), is also known as: the Mesozoic Era the “age of birds and mammals” the Cenozoic Era the “age of reptiles” the Paleozoic Era
Which of the following do not provide evidence that a meteor strike was a partial cause of the Cretaceous-Paleogene mass extinction? a. A potential meteor crater off the coast of Mexico b. High layers of iridium in soil deposits in the geologic record at that time c. Shocked quartz was formed in large quantities at that time around the potential impact site d. An ozone hole appeared in the atmosphere at the time of the meteor strike

Earth’s history is divided into unequal time intervals. The boundaries between the intervals mark significant geological (very early Earth) or evolutionary events on Earth’s history. Example: The boundary between the Precambrian eon and the Phanerozoic eon is marked by the rapid evolution and diversification of organisms with hard body parts. The time intervals are eons, which are subdivided into eras. The eras are subdivided into periods. The periods are further subdivided into epochs (not shown on figure). What is our current eon ______________, era _______________, and period _______________ Age boundary between the Hadean eon and Archean eon __________________ Age boundary between Archean eon and Proterozoic eon __________________ Age boundary between Proterozoic eon and Phanerozoic eon ________________ Age boundary between Paleozoic era and Mesozoic era ____________________ Age boundary between Mesozoic era and Cenozoic era ____________________ What…
Which of these geologic time periods have been defined by a major extinction event? Select all that apply. A. Permian B. Jurassic C. Quaternary D. Cretaceous E. Cambrian
For this activity, you will be reviewing the geological time scale in the module readingassignment from the Geological Time chapter in the PRI Digital Atlas of Ancient Life –online textbook and the Earth History chapter from the OER Commons Earth ScienceTextbook. Use the images of the geologic time scales in your readings to help you makeyour Geologic Time Scale concept sketch nstructions:Sketch and label a geologic time scale. Include dates of the following events in EarthHistory on your time scale in the appropriate time period (you may have to look these up onthe internet but most are listed in your readings). First appearance of free oxygen in the atmosphere Earliest fossils Oldest animal fossils Great Dying Extinction (worst mass extinction at end of the Permian Period) – alsoexplain possible causes of this extinctionArchaeopteryx sp. appeared First Flowering PlantsTyrannosaurus rex appeared K-T Extinction event (Dinosaurs died out) – also explain possible causes of…
Question 1: Mass extinction ocurred on the following time and era except for: A. Mesozoic B. Precambrian C. Paleozoic D. Cenozoic E. All of the answers are correct Question 2: Why would Precambrian Time did not have a lot of fossils? A. fossils were destroyed by extreme heat and pressure. B. soft bodied animals do not leave a lot of fossils. C. majority of the fossils during Precambrian time underwent chemical transformation D. paleontologists haven’t recovered much of the remains of ancient organisms. Question 3: Transgenic organisms have also been developed for commercial purposes most importantly in the agricultural sector. Perhaps the most famous examples are food crops like soy and corn that are now highly resistant to various types of pests. These transgenic organisms are commonly produced by: A. addition, deletion of modification of genes B. gene sequences and programming C. inducing genetic mutations D. genetic transformation by bacteria E. identifying chromosomal…
