This is because the exposed cultural remnants may be displaced by anthropogenic or environmental factors (Blofeld J. 2004 p.71). The buried remains are usually covered with sediments accretion from water and wind erosion or natural processes such as earthquakes, mud flows and earth quakes. Some old structures may also be buried when new ones are built on top of them.
The buried remains are effectively explored through geophysical and geochemical prospecting. These methods are efficient in detecting the invisible characteristics of the remains. The devices used in are significant in distinguishing between relics, which is significant in tracing human remains. The two techniques were developed in a bid to increase professionalism in archeology. The use of geophysics is an effective way of detecting deviations in the magnetic field of the earth through the use of magnetometers. These magnetic fields emanate from artifacts of iron metal as well as structures that were made of stone. Together with these techniques, devices that measure electrical resistance of the soil are also used (Bose R. N. 2005 pp.56-57).
Geophysical and geochemical prospecting are two major techniques that have been widely employed. The two techniques are significant in the identification of human activities that exist as remains buried under the earth surface. The characteristics of the remains are analyzed by an expert who establishes whether they represent human activities or natural factors. The archeological site of Apamee was investigated with the use of the two techniques. They have enhanced the understanding of this archeological site. In the United Kingdom, the two techniques have been applied in many archeological surveys (Braithwaite, R. 2001 pp. 121-123).

Geochemistry of natural waters

...?Geochemistry of Natural Waters Introduction Geochemistry as a science uses the tools and principles of chemistry. By using these principles it tries to best explain the mechanisms behind the major geological systems including those of the earth’s crust and the ocean and this field goes beyond just the earth. It extends to the entire solar system and highly attributing to better understanding of a number of processes such as planets formation and mantle convection. Water is known to be very essential and a basic requirement in the whole geological cycle. Rain water is able to convert the granitic rocks of the continents into sand, clay and other solutes which are better referred to as raw materials that...

...? Geochemistry – Answer ALL questions PART 1. What are the important processes that affect carbonate rocks during diagenesis ? Diagenetic processes range between purely physical ones, bio-chemical and organic processes and physiochemical processes. Carbonate rocks are affected to some degree by all of these processes during diagenesis. The formation of carbonate rocks is affected by dissolution and is important in creating secondary porosity. Similarly compaction and cementation are critical to carbonate rock formation especially for the loss of porosity. Before cementation and compaction, other processes such as bioturbation and burrowing also affect carbonate rocks. Mechanical infiltration also plays a...

Gasoline, even though unleaded, could be dangerous if gets mixed with drinking water and sewage. Underground leakage usually directly mixes with underground water and in this case, it has happened for sometime. Gasoline is a petrol-derived mixture and is inflammable. It has hydrocarbons, and benzene. It is produced in oil refineries, and has between 5 and 12 carbon atoms per molecule. Unleaded gasoline has at least 15 hazardous substances including toluene (35%) and is classified as highly volatile and will result in vapour lock where... First Question:...

...satisfaction leads to decrease in the number of customers which results in increasing costs of finding new customers. As Andrews (2012) states, “keeping customers costs less that finding new ones”. If we analyze the cause of this problem, we come to know that the first problem, which was high employee turnover, causes decreased customer satisfaction. The reason is that new employee who have less experience are unable to develop high quality IT products because they have less knowledge and experience of working at critical positions. When I analyzed the situation at NexGen, I came to know that the company lacked the presence of such employees who could develop IT products as per customers’ requirements. The reason was...

Qualitative Assesment

...Qualitative Assessment Qualitative Assessment Thematic analysis is a qualitative analysis method that aims at identifying, analysis, and recording patterns in the data assessed through in-depth interviews, focus groups, and surveys (Noaks & wincup, 2004). The themes assessed from a given data range are associated to the research question and form the basis for describing a phenomenon. Coding in thematic analysis entails the process of developing themes within the data through recognition of moments in the data and encoding them before interpretation is done (Boyatzis, 1998). Interpretation, thereafter, entails frequency comparison of the codes that represent the themes and showing co-occurrence of themes in the data. Themes... Assessment...
