   In Tanzania natural gas deposits have been discovered at Songosongo in kilwa in 1975 but there has been a delay in realizing full exploitation of gas due to the following reasons; 1) There is low technology among the Tanzanians that can be used in exploiting natural gas at Songosongo island along the coast of the Indian ocean. 2) Low capital to be invested since Tanzania is one of the poor countries. 3) Poor transport [infrastructure] that can facilitate exploitation of natural gas. 4) The use of other available sources of energy like HEP and forest has delayed full extraction of natural gas from Songosongo. Natural gas is a flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum ) and used as fuel. Tanzania has recently managed to exploit natural gas at Songo Songo in Kilwa district within the Lindi region. The gas is processed at Songo Songo and then transported via pipeline to various des...

  Statistics being the scientific and systematic methods dealing with numerical facts is broadly categorized into two types depending on how data is handled. The two main categories of statistics are descriptive and inferential statistics. Descriptive statistics - this deals with recording, summarizing, analyzing and presentation of numerical facts that have been actually collected. Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conclusions beyond the data we have analyzed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data. Descriptive statistics are very important because if we simply presented our raw data it would be hard to visualize what the data was showing, especially if there was a lot of it. Descriptive statistics th...

 HERE SIMILARITIES BETWEEN GROUND-LEVEL PHOTOGRAPHS AND OBLIQUE PHOTOGRAPHS They can both be divided into the foreground, middle, and background during interpretation, unlike the vertical photographs. The scale of both ground and oblique photographs tend to diminish toward the background They are both simple to understand and use In both ground-level photographs and oblique photographs, the objects on the foreground tend to obscure those in the middle and background The size of objects in both ground level and oblique photographs tend to decrease in size from the foreground to the background They are both useful in land use planning and construction activities RELATED POSTS 9 CONDITIONS FAVOURING IRRIGATION FARMING IN EGYPT 5 CAUSES OF RURAL-RURAL MIGRATION IN KENYA 10 AIMS OF KILOMBERO VALLEY IRRIGATION SCHEME 4 FEATURES OF MAP STATEMENT SCALE 10 ADVANTAGES OF OIL PRODUCTION IN THE MIDDLE EAST 7 DISADVANTAGES OF AIR TRANSPORT 10 PROBLEMS FACING COFFEE FARMING IN KENYA IMPAC...

  Soil profile refers to the vertical arrangement of the various soil layers from the top layer down to the parent rock or bottom layer. It is a vertical section through the soil horizons extending into the parent material or the bedrock. It describes the sections downwards through the soil which comprises differing characteristics in terms of texture, color, mineral composition, the ratio of the combination of organic and inorganic matter, hardness, and rate of weathering . The different layers are referred to as horizons. A soil horizon is a well-defined layer within the soil profile parallel to the local round surface. There are four main horizons namely: A horizon, B horizon, C horizon, and D horizon. Each horizon has different physical and chemical properties, which result from various soil-forming processes such as weathering, the introduction of humus, and the movement of minerals . O-HORIZON This is the topmost/ surface layer of the soil comprising organic matter . The con...
