Geologic time scale

the scale of the operation. With such a high level of responsibility and independence, working at the Days Inn gives me the opportunity to improve on a valuable skills everyday. These skills range from answering phones, entering data into spreadsheets, to dealing with unpredictable situations that nothing could prepare me for. In one occurrence there was water dripping

compound, usually of crystalline form that can be manipulated and used to make something else. A rock is the solid mineral material that forms on the earths surface, and in the ocean. We use different rocks and minerals based on the geologic timescale and the human time scale. Rocks and minerals are the building blocks of life. They make up materials, that we use every day unconsciously.

Geological and Dispositional History of the Starved Rocks, Illinois Describe the clastic and carbonate facies you have discovered. Starved Rock State covers about 200 miles and some 470 million years, from Ordovician sandstones to Pleistocene glacial till. The Ordovician St. Peter Formation sandstone was deposited across the midcontinent during the second major marine transgression of the Paleozoic Era. The first transgression deposited Upper Cambrian to Lower Ordovician clastics and carbonates

Since the end of the last century, the development of modern technology and science has played a significant role as measure to resolve energy crisis and global warming issues which resulted in life sustaining remedies and causes of mass destruction. However, many scientists agree that the earth’s fossil fuel supplies are dramatically depleting and this challenge will be a meaningful hurdle for future generations. Therefore, many countries may need to find new productive energy sources in order to

islands are known as Wallacea and they also have a very distinctive set of species that live on them. Even the birds, which are capable of migrating to and from the mainlands of Asia and Australia seem to stay put and have diverged over long periods of time. It is not known if the differing landforms serve as a way for the animals to know the boundary, or if it is something else that keeps the species from traveling from one side of the Wallace Line to the

that geological time scales are defined solely by their beginnings” (Finney and Edwards, 7). According to the AWG, the suggested start for the Anthropocene is 1945 (Finney and Edwards, 7). An indicator for this date is “the human human-caused atomic detonations” that resulted in the spread of atomic radiation across the planet (Zalasiewicz et al., 2230). In defining the Anthropocene based on its cause and date, and using the definition as grounds for justification as a geological time unit is where

Throughout the course of the earth, there have been many impressive geologic events that have taken place. Natural disasters ranging from volcanic eruptions, to massive earthquakes, to avalanches make their marks known after they strike. The natural disaster that I want to focus on specifically in this paper, however, is tsunami’s. Though Tsunami’s are arguably the most deadly natural disaster, they are also one of the most amazing geologic events to witness. Over the course of this paper, I will outline

Bathymetry derived terrain variables are indicative of seabed morphology and can be used as predictors of suitable benthic habitats. A digital elevation model (DEM) is a digital representation of the elevation of locations on the land surface, and in the case of this report can be used as a digital representation of underwater bathymetry. The DEM can be used to derive various benthic terrain variables of underwater systems (Pescus 2012). Some terrain variables include depth, slope, rugosity, aspect

The earth has existed for about 4.6 billion years; the geologic scale divides all of these years into sections, much like chapters in a book. Each of these sections is unique because it shows all of the changes on earth’s surface throughout the years. The largest of these sections on the geologic scale is eons. Eons are also divided into another two sections call ears. Eras are then divided into periods and then periods are divided into epochs. The reasons why the sections have been divided are either
