Geomorphology

Coastal geomorphology is similar to geomorphology, but the area of focus is on seas and oceans (Davidson-Arnott, 2010). Researches study the development and progression of the coast and how it reacts under particular conditions including sea level changes. The IPCC (Intergovernmental Panel on Climate Change) report in 2013 stated that sea level rise will occur in approximately 95% of the ocean area, with estimates that seas will rise between 26 and 82 cm. Therefore, we can assume it is probable that the geomorphological changes on the coast will have a profound impact on the existing landforms. In this essay, I will describe the predicted impacts on coastal geomorphology in relation to sea level rise. Sea level rise is attributed to four main…

Introduction Quaternary climatic changes and tectonic processes have a strong influence on the evolution and preservation of the geomorphology of the eastern North Island of New Zealand. This essay will discuss the broad context of Quaternary environmental change and tectonics in the eastern North Island of New Zealand and then will examine how both these concepts influence the geomorphology, whether affecting separate aspects of the landscape or combining and working together. Examples of…

The Elena Gallegos Open Space area sits near the base of the Sandia Mountains on a piedmont surface. This exercise was intended to gain insight into the mountain-front landforms of the Pino Embayment area. Through the use of surficial geological mapping and soil descriptions we were able to establish relative ages of geomorphic surfaces of the area and determine whether the area displayed qualities of alluvial fan and pediment surfaces. The geomorphic setting of the study area showed…

Standing on what was once a piece of oceanic crust, laid down in the Ordovician period 450 million years ago, I was captured by the astounding power behind the forces that had moved this exact piece of crust over exceptionally long periods of time to be situated inland, adjacent to a river, to where it is in the present day. Taking on Geology was a decision I made based on my thorough enjoyment and fascination of the physical aspect of geography at GCSE, particularly learning about volcanoes,…

The formation of Mississippi Deltaic Plain (MDP) requires comprehensive work between the river and multiple coastal scales, such as temperature and space. It is very important to restore the MDP not only because it helps to understand the details that are needed to ensure the sustainability of the delta system, but it also possesses the potential to mitigate future damage from climate change to coastal ecosystem. The contribution of riverine inputs increase accretion and bulk density, benefit…

Rough Draft for Essay Volcanos, what are they? How would you know when one could happen near you? The first question to ask is how many active volcanos are there? The next question would be what happens when a volcano erupts? The last statement would be volcanos in Hawaii. How many active volcanos are there? “The answer to this commonly asked question is up to the word active” (Simkin 58). About 20 volcanos erupt every couple of seconds (Simkin 58). There are about 50 to 70…

Figure 1 below illustrates the predicted route of the track as identified during the least cost paths analysis. The four parts of the route are shown: Punakiki to the ventilation shaft; shaft to the mine portal (lookout point); portal to the amenities area; and the ventilation shaft to Blackball. The results clearly illustrate it is possible to use cost paths modelling to identify a track. However, further assessment will be necessary around the aesthetic value of the track, to assess whether it…

Results: In Tully Valley, the mudboils are where pressurized groundwater flows up through a restricting layer of silt, clay and fine sand. Mudboils usually take place in subduction zones of the Earth. The mudboil causes the land surface to slowly decline and the erosion of suspended sediment which creates a sequence of concentric ring fractures around the discharging mudboil. Mudboils are driven by pressurized groundwater, geothermic heat, and gases. As a consequence, the mudboils…

Many people in the world today wonder who and what shapes the earth. In this informative essay, you will learn just that. How is the earth shaped? The answer to that is people and nature. Erosion is a big part of shaping the earth. Some different kinds of erosion are wind erosion, and water erosion, when something erodes, that means that it is tearing away at something. Because there is water flow, erosion causes the water to work its way through cracks and expand them. When it is windy…

Backround: Water erosion is when water moves loose soil and alters the earth's landscape. There is 4 types of forms for water erosion, Rill, Rill is a type of water erosion that creates small channels of water on a sloped surface. Splash, Splash erosion is direct movement of the soil when it splashes on the ground, soil can be splashed up to 3 ft away by rain. Gully,Gully erosion is when water creates wide channels in the soil. lastly Sheet. Sheet erosion is when a thin layer of soil is…
