Archeology examines

Archeology examines archeology in the lives of peoples and ancient civilizations, and examines the remnants of such civilizations as: the remains of buildings, coins, bones, tools, and these wastes show the way of life of peoples, and helps to identify their civilizations, and the way of development, and the causes of the fall of these civilizations. Scientists use many modern methods and techniques to search for archaeological evidence in a precise and systematic manner. Records are recorded with the evidence found and we will discuss in this article some of the methods used to search for archeological sites. Where the effects can be found underground, above ground or under water, such as: the remains of sunken ships or cities that have been flooded by changes in the surface of the earth or the water level. The site is determined on scientific grounds through Clear the location and the T in a specific destination, and uses aerial photography to see the differences in plant growth, which indicate the presence of archaeological evidence, mineral and reagents to search for metal tools. Site Survey Scientists, by searching for a particular site, describe the site, record detailed observations, describe the archaeological evidence, take pictures of the site and map it simplified after measuring the dimensions in steps or measurement condition. There are many special tools used to survey the site and detailed mapping of the site, and after mapping the researchers collect some of the archaeological evidence in the site, and is divided into small spaces, and study each area separately and then recorded on the map where the existence of artifacts that help in searching systematic. The method is based on the location, climate and nature of the soil. It is used in the excavation of tractors, heavy machinery, small tools and brushes. The soil can be sifted for small pieces. The soil can be analyzed in the laboratory to detect evidence and human waste. . Underwater work Scientists look for underwater effects using several methods, such as aerial photography, which may reveal the features of a whole city immersed in water. The survey uses sonar based on acoustic waves to detect underwater effects. Metal detectors can be used to detect the presence of materials The divers can draw detailed maps of the site using underwater cameras and use balloons to lift heavy materials for accurate study.
