Sediment

associate professor Daniel Clay Kelly in UW-Madison’s Department of Geoscience, studies the history of the earths’ climate that, explains how ocean acidification and rising carbon dioxide levels are causing catastrophic damage to our planet. Deep-sea sediment records are used as an archived of the Earth’s climate that spans the last 170 million years of earth’s history. “As paleontologists and geologists, we know the rock record is incomplete,” said Kelly. “It’s like…

adaptations. Trilobite fossils are one of the most common fossils to be retrieved. It is believed that their widespread population as well as their ocean floor habitat ensured that many met the strict conditions for fossilisation- rapid burial in oceanic sediment after…

Geologic time scales often last thousands of years, and it is easy to tell when they begin and end. The current geologic time scale has present day humans living in the Holocene period which began almost 12,000 years ago. Recent debate has begun, however, that proposes a new period. Since humans have had such a large effect on the Earth, especially in the last few hundred years, various scientists want to see this period of human effects as its own section on the geologic time scale. This…

The Holderness coast is located on the east coast of England. Although it is popular among tourists and bird watching afrionados, at the same time, It is one of the Europe’s fastest eroding coast lines. Approximately 2 million tonnes of material get eroded, which is about 1 to 2 meters of erosion occurs every year. Because of this rapid erosion, about 30 villages have been sank into the sea since the Roman times. This is due to the fact that the Holderness Coast is made of Cretaceous Chelk, and…

Transfer RNA Transfer RNA (tRNA) is a crucial component in Protein Synthesis. It serves as an adaptor molecule between the codon, the three nucleic acids and the amino acid after which a specific protein will be synthesized. It is the intermediate in Protein Synthesis which interprets the genetic code. Without tRNA, translation in prokaryotes or eukaryotes could not take place. Common Features of tRNA Molecule Each amino acid has at least one tRNA molecule. Therefore, these tRNA molecules have…

coral reef it is essential that the water situation is clear and salty water that has low levels of phosphorus and nitrogen. This is impossible to accomplish if pollution is infecting our reefs. People are also using the ocean to dump materials (sediment, plastics, metals, and more), which encourages animals to use this as a food source. Stated by Shwirk “Every year,…

If the water is turbid, murky, or has any visible sediments, then it needs to be filtered. To do this, pour the water through clean cloth or coffee filters. Repeat this step until the water is clear; this indicates that it is ready to be disinfected. There are several options to disinfect water. The most…

“Unmasking “fresh water” Until recently I hadn’t given much attention to the type of water consumed both by myself and by my family. During a recent geology lecture I was shocked, appalled and amazed to discover how little treatment is actually conducted on water before it is released back into the original source. In an effort to better understand the subject, I have reviewed many materials both online and in print. I have contacted my city and spoken to several experts on the topic. I…

Henry David Thoreau once said “Heaven is under our feet as well as over our heads.” (Thoreau, n.d.). To one that takes the time see what majestic features the earth has and creates in a one’s life time is breath taking. The hydrologic cycle is one interesting aspect that will be discussed and the state of Colorado will be used as an example. Another such wonder is the glacial landscape. How a glacial landscape is formed and some of its features will be discussed as well. Hydrologic Cycle The…

fourth grade unit on earth 's systems, and more specifically: soils, rocks, and landforms. The disciplinary core ideas that this standard is addressing exist in two parts, ESS2.A which focuses on rainfall shaping the land and the movement of sediments through water, ice, wind, and vegetation, and ESS2.E which primarily focuses on living things affecting their surroundings. (NGSS) While brief, both of these core ideas also show up again in the NAS K-12 framework as skills in the 5th grade…
