Alternating patterns of distinct laminae are commonly identified within glacial lake deposits and are generally interpreted in the following way: However, there is actually no empirical evidence to back the claim that varves form as annual deposits over extended periods of time. It appears then, that claiming a varve is an annual event is an assumption in itself; one steeped in uniformitarian thought, but not reality. Geologists have known for quite some time that multiple laminae may form very rapidly. French creation scientist Guy Berthault performed groundbreaking laboratory experiments demonstrating that multiple laminations can form spontaneously when sediment mixtures consisting of particles of different sizes are deposited in air, running water, or still water. This occurs because particles of different sizes have a tendency to spontaneously segregate and stratify themselves.

The language of man follows things and imitates them; the Word of God precedes and creates them. Man speaks because things are; but these are because God hath spoken. Let Him speak again, and things will revert together with man who speaks of them, to nothing. Let us be content to perceive in creation a character which belongs only to God, and which distinguishes His work from that of His creatures. The human mind works only with the materials with which God supplies it; it observes, imitates, combines, but does not create.
The best painter in the world, composing the most beautiful picture that ever proceeded from the hand of man, creates nothing:
Dating of Rocks, Fossils, and Geologic Events CONTRIBUTING AUTHORS ACTIVITY Absolute Dating of Rocks and Fossils Pencil, eraser, laboratory notebook, calculator, colored pencils, plus a ruler and protractor cut from GeoTools Sheets at the back of the manual.
Interpret successive layers of sedimentary rocks and their fossils to infer relative ages of rock sequences, past geologic events, changes in environmental conditions, and the appearance and extinction of life forms. Use relative dating techniques to explain how the structures of the Earth and life on Earth have changed over short and long periods of time. Explain how rocks and fossils are dated.

The granite crust is generally estimated to be at least 50 km 30 miles thick. Therefore, steady state has not been reached. In other words, radioactivity is concentrated in the crust but has not been there long enough to reach steady state. In fact, so much heat could be developed in this way that it has been practically necessary to make the assumption that the radioactive materials are limited in occurrence to a surface shell only a few kilometers in thickness. University of Wisconsin Press, , p.
All three of the radioactive elements are strongly partitioned into the continental crust. In general, the heat production rate must decrease with depth. Otherwise, surface values would imply zero or negative mantle heat flow. In other words, the rocks directly below the Moho would have melted—an easily detected condition.
Decades ago, students were taught that the mantle was a liquid. Even today, some textbooks make this erroneous claim. If the mantle had only a thin, continuous shell of liquid at any depth, certain seismic waves shear waves, also called secondary waves could not pass through that shell. However, seismometers all over the world measure those waves daily. Does this mean that the bigger your feet, the better you write?

A Twa hunter-gatherer in Uganda climbing a tree to gather honey. Nathaniel Dominy Early Human Ancestors May Have Walked AND Climbed for a Living Africa 31 December The results of recently conducted field studies on modern human groups in the Philippines and Africa are suggesting that humans, among the primates, are not so unique to walking upright as previously thought. The findings have implications for some of our earliest possible ancestors, including the 3. Associate professor of anthropology Nathaniel Dominy of Dartmouth College, along with colleagues Vivek Venkataraman and Thomas Kraft, compared African Twa hunter-gatherers to agriculturalists living nearby, the Bakiga, in Uganda.

Topics include major events, persons, and issues spanning the period from the African heritage to contemporary times. Students survey the evolution of African American expressive culture in music, literature, film, art, and dance. The course includes lectures, discussions, and video presentations. Besides being the first rap artist to be inducted into the Songwriters Hall of Fame and holding the record for the most number one albums by a solo artist, JAY-Z’s body of work stands as a monumental contribution to American culture.
In this course, we explore the poetics and philosophy of JAY-Z’s music. As we cultivate an artistic appreciation for JAY-Z’s rap skills such as storytelling, wordplay, and delivery, we also treat his music as an opportunity to critically engage topics such as racism, sexism, and economic inequality. Finally, we watch several of JAY-Z’s music videos as well as documentaries focused on his life and work. Psychology of Prejudice In this course we will explore psychological approaches to understanding stereotyping, prejudice, and discrimination–the psychology of prejudice, for short.
We will examine research and theory on topics such as historical changes in the nature of intergroup attitudes; the prevalence of prejudice in the U. Africana Women’s Religious Experience. This course explores the multidimensional religious experiences of Africana women, specifically Black women throughout the Americas, Africa, and the Caribbean, as they attempt to define and realize a sacred self across diverse periods and contexts.
We give attention to the voices of Africana women in history and literature, film, performance, sacred speech and music to examine the ways religion has empowered and disempowered Black women in their individual and collective lives. African American Literature I A study of slave narratives and contemporary revisions. African American Literature II An examination of narrative attempts before, during, and after the Harlem Renaissance to move from imposed stereotypes toward more accurate representations of African American experiences.

Evolution as fact and theory Critics of evolution assert that evolution is “just a theory,” which emphasizes that scientific theories are never absolute, or misleadingly presents it as a matter of opinion rather than of fact or evidence. Evolutionary theory refers to an explanation for the diversity of species and their ancestry which has met extremely high standards of scientific evidence.
An example of evolution as theory is the modern synthesis of Darwinian natural selection and Mendelian inheritance.

Earth processes have not changed over time. Mountains grow and mountains slowly wear away, just as they did billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct, meaning that they die out completely. They use clues from rocks and fossils to figure out the order of events.
They think about how long it took for those events to happen.
A recent post here about thawing permafrost releasing climate-warming carbon dioxide into the atmosphere was no exception. As CO2 has had no noticeable effect on climate in million years, until 20 years ago, when carbon tax was invented, any alleged climatic effects can be ignored. I ordinarily ignore comments like the one I quote above. Discover is a science magazine, not a platform for political grandstanding.

On the wet sand right this does not happen. The Egyptians moistened the sand over which the sledge moved. By using the right quantity of water they could halve the number of workers needed. The researchers published this discovery online on 29 April in Physical Review Letters. For the construction of the pyramids, the ancient Egyptians had to transport heavy blocks of stone and large statues across the desert. The Egyptians therefore placed the heavy objects on a sledge that workers pulled over the sand.
Research from the University of Amsterdam has now revealed that the Egyptians probably made the desert sand in front of the sledge wet.

Evidence for a Young World by D. European Southern Observatory Here are fourteen natural phenomena which conflict with the evolutionary idea that the universe is billions of years old. The numbers listed below in bold print usually in the millions of years are often maximum possible ages set by each process, not the actual ages.
The oldest undisputed fossils are from rocks dated around Ga, and although fossils this old are typically poorly preserved and are not useful for dating rocks, they can still provide important information about conditions at the time.

Richard Cowen’s Chapter Eight: Leaving the Water – images – curent page , , to , , years ago Eurypterids, otherwise known as sea scorpions. Wikipedia Late Ordovician survivals and extinctions: There were no land animals and extinctions were confined to water life. There were two distinct extinctions roughly a million years apart. The first of these began about million years ago.
Together, these extinctions may have removed about 85 percent of species of marine animals. All of the major animal groups of the Ordovician oceans survived, including trilobites, brachiopods , corals, crinoids and graptolites, but each lost important members. Widespread families of trilobites disappeared and graptolites came close to total extinction. Graptolites rock writing are thought to be horny skeletons of small creatures.
