5 DISADVANTAGES OF SIMPLE CHAIN SURVEY

 A chain survey is a simple land survey that deals with measuring and recording a series of linear distances on the ground by using a chain or a tape measure.

The chain survey is the simplest method of surveying. In this survey, only measurements are taken in the field, and the rest work, such as plotting calculation, etc. are done in the office.

5 DISADVANTAGES OF SIMPLE CHAIN SURVEY


This is most suitable adapted to small plane areas with very few details. If carefully done, it gives quite accurate results.

The necessary requirements for field work are chain, tape, ranging rod, arrows, and sometimes cross-staff.

The following are disadvantages of simple chain survey:

  • A simple chain survey can not be conducted in built-up areas and large areas.

  • A simple chain survey is subject to several chances of errors of accumulation which may be caused by the problem of the chain. The chain linkage may fail to stretch up properly and result in inaccurate data. Also clogging of the chain may read to an error in reading.

  • It is time-consuming

  • It may not be conducted in areas with steep slopes or waterlogged areas. chain survey is usually conducted in dry areas with gentle slopes. It becomes more complicated when a survey is conducted in areas that are too wet.

  • Chain survey becomes a more complicated method when there are raised points (obstacles) in between areas to be surveyed.

5 TYPES OF HUMAN ACTIVITIES

Image
  Human activities are functions, tasks, or works done by human beings over time for achieving certain purposes. In total there are five types of human activities namely primary human activities, secondary human activities, tertiary human activities, quaternary human activities, and quinary human activities. These types of human activities together with their examples are going to be explained one by one below. The following are five types of human activities Primary human activities are human activities that involve extracting raw materials directly from the earth. Examples of primary activities are farming, fishing, lumbering, and livestock keeping. Secondary human activities these are human activities that involve the processing of raw materials into useful products. These activities involve converting raw materials into finished products and are mainly performed in urban areas. they accelerate the development of primary activities because they provide the market for products fr...

ROCK CYCLE - DEFINITION

Image
  Rock cycle is the cycle in which rocks tend to change from one type to another. For instance, igneous rocks may change to metamorphic rocks or sedimentary rocks ; sedimentary rocks to metamorphic or igneous rocks, etc. It is a relationship in which rocks tend to change from one type of rock to another.   Necessary conditions for rock cycle to take place 1. the molten rocks are erupted from the interior of the earth and then cool and solidify to form igneous rocks. 2. the igneous rocks are subjected to denudation process to form sedimentary rocks. 3. either igneous or sedimentary rocks undergo metamorphism, due to prolonged heat and pressure, to form metamorphic rocks. 4. metamorphic or igneous rocks can undergo weathering process through erosion and transportation of sediments which are further deposited in layers in the ocean or lake floors where they are cemented and consolidated to form sedimentary rocks and vice versa. 5. metamorphic or sedimentary rocks can be ...

10 FACTORS INFLUENCING POPULATION DISTRIBUTION IN EAST AFRICA

Image
THE FOLLOWING ARE FACTORS INFLUENCING POPULATION DISTRIBUTION IN EAST AFRICA Climate Areas that receive heavy and reliable rainfall which support the growth of crops have attracted people in large numbers e.g. shores of Lake Victoria, Kenya highlands, slopes of Mt. Elgon and Kigezi highlands while areas that receive low and unreliable rainfall attract very few people e.g. Karamoja, Turkana land and Miombo woodlands. Soils areas with deep and well-drained fertile soils that support agriculture have attracted dense settlements e.g. Mbale, Kabale, shores of Lake Victoria while areas with infertile soils have sparse populations e.g. Nyika plains, North Eastern Kenya and Masai land. Altitude/relief areas with very high altitudes e.g. top of Mt. Elgon and Rwenzori, Bundibugyo have a sparse population because of the high pressure, difficulty in constructing houses and roads. However low altitude areas have attracted large settlements due to ease in constructing settlements and roads. Howeve...
