All are invited to submit abstracts and teaching demonstration proposals to the conference’s contributed program by March 1. Groups wishing to conduct a concurrent working group session at the Rendezvous should also submit an application by March 1. InTeGrate Spring Webinar Series Begins Free and open to the public, the InTeGrate Spring Webinar Series will incorporate InTeGrate pedagogies into teaching practices, provide resources available for adoption, and create a forum for participants to learn and share teaching strategies. New Developments in Diversity and Inclusiveness in Geosciences In an upcoming edition centered on the theme of New Developments in Diversity and Inclusiveness in Geosciences, the Journal of Geoscience Education JGE will explore issues on pipeline development, recruitment and retention, graduate education and special topics such as minority serving institutions and non-traditional opportunities in both case studies and broad research investigations. Potential authors should submit a letter of intent by April 1, The bi-weekly blog posts address topics related to supporting students’ academic success, facilitating students’ professional pathways in the geosciences, broadening participation in the geosciences, and catalyzing change. InTeGrate is developing a new breed of teaching materials that can be utilized in general education courses, teacher preparation courses, core courses within geoscience majors, and courses designed for other majors including environmental studies, social science, engineering, and other sciences.

Thus, the layers are successively younger, going from bottom to top. The convention in geology is to number the layers beds within a sequence such that the oldest layer has the lowest number. In the illustration, layer 1 was deposited at time 1. At time 2, layer 2 was deposited on top of layer 1. At time 3, layer 3 was deposited on top of layer 3.

He deduced that the layered rock were sediments laid down in marine and continental environments by procxesses and at rates currently observed. This became to be known as the principle of uniformitarianism and led to the establishment of relative ages of the various rock layers Measurement of rates of sedimentation then led directly to the discovery of the great antiquity of the Earth. Relative Age is determining the sequence of geologic events that have occurred in a given area and can be established on the basis of several intuitive principles: Sediments deposited in water were originally flat lying.
Correlations of events from one region to another are based on: The geologic evidence led these workers to advocate an age of teh earth of hundreds to thousands of millions of years which put them in direct conflict with the catastrophism of the contemporary church. Charles Darwin was a contemporary of Lyell, and agreed that vast expanses of time were reuired for biological evolution to achieve the observed degrees of complexity.
The geologists and biologists then encountered arguments based on thermodynamics for a much younger age of the Earth. Lord Kelvin, a British physicist who had done much to advance our understanding of heat generation and conservation of energy, assumed that the sun’s energy was due to gravitational collapse and calculated the amount of energy that could be thus derived.

Alpha decay The process of radioactive decay in which the nucleus of an atom emits an alpha particle. The new atom’s atomic number is lower by two and its atomic mass number is reduced by four. Richardson Alpha particle A particle consisting of two protons and two neutrons, produced during alpha decay.
Review of Relative Dating. In previous lessons, we talked about the Geologic Time Scale and how scientists use it to piece together the history of the earth.
Geologic history — relative age dating: This type of exercise applies the principals of relative age dating you studied in the text to deduce the order of geologic events. Please review the 5 principles before you start the exercises. In this type of exercise list the oldest event at the bottom of the page and progresses upward to the youngest event. The question that many people have is where do I start? It is useful to identify the unconformities which represent breaks in the geologic time record.

Rest and satisfaction In light of these correspondences, Kline interprets days one and four as different perspectives on the same event, and likewise days two and five, and three and six. He concludes that while the creation account is historical, historicity and narrative sequence are not the same thing, so the account need not—indeed, should not—be read as chronological at all.
And, of course, this nicely addresses Origen’s observation that days one, two and three could not be literal days before the sun, moon and stars existed to mark them and it also obviates the anachronistic modern question, relevant to all six days if they are literal, of the time zone by which God measured his evenings and mornings Garden of Eden Standard Time? Of course, Kline’s interpretation can be disputed. For instance, Collins , while recognizing the validity of the parallel structure in the days of creation and appreciating the implication that the precise lengths of time involved and the precise historical ordering of events was not the author’s focus and is not a matter of deep biblical importance, nonetheless resists Kline’s effort to condense the divine “workweek” into three days told from two different perspectives rather than six.
The fourth commandment in Exodus Furthermore, use of the Hebrew wayyiqtol verb form is prevalent in Genesis 1 and, since its ordinary narrative use is to indicate sequential events Collins , the implication seems to be that some sort of sequence—whether logico-metaphysical, teleological, or chronological—is intrinsic to the author’s portrayal. Adopting this viewpoint, however, leaves Collins with the problem of interpreting how the fourth day of creation fits into this sequence. He resolves it by noting that when God says “Let there be yehi lights in the expanse of the heavens to separate the day from the night.
This interpretation is further bolstered by the fact that verse 14 is focused on the function of these lights rather than their origin, lending credence to Collins’ argument that Genesis 1:

Describe why the feature at Siccar Point requires a long history. Apply the principles of relative dating to a photograph or sketch showing geologic relations among several rock units: A younger rock or feature can cut across any older rock or feature. Disconformity if rock layers are not tilted before they are overlapped by younger layers. But the boundary still represents millions of years of time.

It is widely accepted that the Earth is about 4. There are two techniques geologist use to obtain the Earth’s age: Radioactive dating and Relative dating. We will discuss radioactive data later. Many rock formations are layered.

How does a global flood explain angular unconformities? These are where one set of layers of sediments have been extensively modified e. They thus seem to require at least two periods of deposition more, where there is more than one unconformity with long periods of time in between to account for the deformation, erosion, and weathering observed. How were mountains and valleys formed?
Many very tall mountains are composed of sedimentary rocks. The summit of Everest is composed of deep-marine limestone, with fossils of ocean-bottom dwelling crinoids [ Gansser, ]. If these were formed during the Flood, how did they reach their present height, and when were the valleys between them eroded away? Keep in mind that many valleys were clearly carved by glacial erosion, which is a slow process.
When did granite batholiths form? Some of these are intruded into older sediments and have younger sediments on their eroded top surfaces. It takes a long time for magma to cool into granite, nor does granite erode very quickly. One formation in New Jersey is six kilometers thick. If we grant days for this to settle, and ignore possible compaction since the Flood, we still have 15 meters of sediment settling per day.
