2.2.3 Definition of Chelating Ligand EDTA From the above discussion, it can be concluded that chelating ligand EDTA is a process of reversible bond formation of a ligand that serves as chelating ( chelting agent or Chelator) that exist within the compound of EDTA. Basically, EDTA combines with some specific ion, so it causes the functions of EDTA as chelator. When the functions of EDTA as chelator, EDTA is a liquid ( solution) 2.3 Volcanic Ash Volcanic ash or sand is volcanic material debris…

The Halifax Explosion was caused by a French cargo ship (Mont-Blanc) full of explosives that collided with a Norwegian vessel. It occurred in a Strait that connected the Bedford Basin to the upper Halifax Harbour. When the ships collided, a fire ignited on the French cargo ship which set the explosives off. 2000 people were killed by the blast, debris and the buildings that collapsed, and about 9,000 were injured. At 8:45 A.M., the ships were going about 1.6 to 2.4 kilometres per hour when they…

In 79 CE, August, Mount Vesuvius had a significant eruption, that went on for nineteen hours, burying an ancient Roman city for seventeen centuries. This city was near the modern Naples within the Italian Region of Campania. The buildings and many of the people were buried and lost until the discovery made in 1738. This city is known as the lost city of Pompeii. Mount Vesuvius is a stratovolcano that consists alternate layers of ash and lava. Stratovolcanos have two types of eruption, one…

Sciencia is a world analogous to Eath. Based on the present day plate boundaries and similarities on multiple continents, It’s believed that the continents of Sciencia were once together as a supercontinent called Edisonia. The supercontinent held 6 of the 8 modern continents, which broke apart due to tectonic forces in the Lithosphere. Also, the 7th and 8th continents were believed to have formed from volcanic eruptions on convergent plate boundaries. The edges on the modern- day Sciencian…

it is the tectonic plates. The Earth’s crust and upper mantle, also known as the lithosphere are made up of seventeen pieces know as Tectonic plates. Because directly below the crust is a deep liquid layer underneath the crust is which results in the plates shifting around.The boundaries of a tectonic plate are either known as divergent boundaries(two plates moving away from each other) , convergent boundaries (two plates pushing against each other) subduction zones(one plate going underneath…

When the North American and Pacific Plates collided, the force pushed and curved the San Andreas forth towards San Francisco, California. As more and more aftershocks came, more powerful and large fires overcame the city. The fires wiped out much of the remaining people and structures. Overall, the main cause was the movement of plates around the Earth. The earthquake of San Francisco burned down many houses and buildings, making it…

Shale of the Appalachian Basin With various depositional environments and the understanding of sea level change, the Appalachian Basin formed by the collision of tectonic plates and sediment accumulation under the Earth’s surface. The Appalachian Mountains reveal subsidence belts, faulted marine sedimentary rocks and other geologic rocks in these tectonic settings. The Basin exists in the northeastern states of North America. This large rock formation exhibits collisional tectonics with modern…

Objectives Determining the age at death of a skeleton can be complicated and possibly difficult dependant on state of preservation, bones present, or archaeological context. By using measurements of the present long bones and the data that correlates the fusion times of the distal and proximal epiphyseal unions, an age at time of death can be narrowed down to a less broad range. While this measurement method is not completely accurate, dentition ageing techniques and cross referencing of the…

Mountains, and the Davis Mountains. The Rio Grande Rift expands from Colorado all the way to Chihuahua, Mexico. Earth surfaces began to pull apart around 30-35 million years ago. In this process, there were volcanic activity and moving of tectonic plates that have created much of what you can see today in the region. This includes many mountain ranges, the Rio Grande River, and Potrillo Volcanic Field. The Rio Grande Rift is still active and moves between .5-2mm per…

There are many methods scientists estimate earthquake probabilities. One technique is using the Global Positioning System (GPS) which permits geologist and scientists to make precise measurements of existing plates in motion. About 1.6 inches per year in the San Francisco area. The history of recent large earthquakes in a specific place helps determine the future of similar great shocks. Another way to estimate the chance of earthquakes occurring is finding…
