Holocene

Climate Change is mainly caused by excess greenhouse gases in the atmosphere, relative to the holocene period. The holocene period is the only period we know to support human life. The most common greenhouse gases are Carbon dioxide (CO2), Methane (CH4), Water Vapour (H2O) and Nitrous Oxide (N2O). These gases cause increasing atmospheric and earthly temperatures…

The Museum of Natural History on the University of Iowa campus is located in the McBride Hall on the Pentacrest of the university. I arrived at the museum on a Friday afternoon around 1p.m., the building was mostly empty and the exhibit was easily accessible. I have been going to the museum since I was a child because it was a favorite of my parents. The museum had always kept me busy for hours at a time exploring and looking for things that I have not seen before. Since becoming a student…

As our book states, there are three periods in which early human life occurred in North America. These three periods are the Paleo-Indian, the Archaic, and the pre-Columbian. The Paleo-Indian era occurred around ten thousand to fifteen thousand years ago and is when the settlers appeared in America. They traveled to America from Asia in search of food. They traveled, by following the herds of wooly mammoths they were hunting, over a "narrow passage of iced-over land called Beringia" which is…

self-heed might be the most encouraging individual distinction variable star, giving criticism would supports one's self-regard as they feel they are doing their employment or errand effectively. It can be a congratulatory gesture, commending their most Holocene workplace that is fruitful anything that would feel them that they are required and not a risk of exposure in the organization or even in a work…

Arguably, not many things have shaped the human history as much as domestication has. The transition that started in early Holocene around 11 000 years ago from nomadic hunter-gatherer lifestyle to more settled existence of agriculture has been vital for the development of human societies as we know them now (Gupta 2004, Brown et al. 2009). The first steps for this transition were taken in multiple places independently, one of which was Southwest Asia and especially the area called Fertile…

Though, the diatom species have a long stratigraphic record from upper Cretaceous to Holocene, many short ranging species with few million years or less serve as a well-developed biohorizon with ages calibrated to the radiometrically dated geomagnetic timescale. The combination of multiple tools including diatoms results in age control of…

Active Volcanos Are There” by Tom Simkin, “There was roughly 60 volcanic eruptions each year in the 1900’s; and 154 have erupted in the full decade of 1990 and 1999; about 550 have had historical documented eruptions, and some 1300 have erupted in the Holocene” (Simkin 58). These…

If global warming were a bush, the people and politicians of the world have been beating around it for more than a century. While aware that the earth is slowly heating up, already by .8°C since 1880 when scientists began keeping reliable record, little has been done to control it. But is this scale of temperature control even within human capabilities? Some claim that climate change is merely Earth 's natural agenda and that humans couldn 't control it if we wanted, while others believe it is a…

reservoir rocks, cap rocks, and traps that led to the formation of oil in the basin. The basin itself is constituted, as described by Biddle et al ( 1991), has a cumulative thickness greater than 9 km and consists primarily of of middle Miocene to Holocene age sediments ( Hayba, 1995). Mainly consisting of sand, silts, and clays, the source rock of hydrocarbons found…

ago, the most recent of apocalyptic extinction events occurred, wiping out the dinosaurs and signaling the start of a new era. The Cenozoic Era (age of mammals) has been split into seven sections called epochs with the final epoch being called the Holocene epoch, which brought forth a new ecosystem that harbored humanity. To conclude the eras that occurred previously, there have been five apocalyptic extinction events that occur roughly every 100 million year, and considering that humanity is 70…
