Groundwater

 

A related how groundwater and springs are trained how groundwater is made that the water sources in Saudi Arabia called science that studies the reliefs knowledge of geography, while the supposed science that studies nature of the Earth and the nature of the forms with knowledge of the field, the general Elman are connected and sometimes interlaced both, but the most important features Tmisahma that the majority of the geography concerned with what is above the ground while the majority Earth interested in what is inside it Sciences and is interested in the description of the geography while cares analysis of Earth Sciences, and to form a good view of the planet, we must educate ourselves flags so as not to be incomplete our knowledge and where the gaps may lead to a misunderstanding. Areas formed on the surface of the Earth from the research plots of land, and land covered with water, and excels covered with water in terms of space occupied by three-quarters of the surface of Earth, Earth open or covered spaces with water containing the topography of a multi-floor Aaljebal and hills and valleys and volcanoes, and vary in nature in terms of its components rocks species pose, soil and water on the planet, it is divided into several forms, including bodies of water from the 
ocean and huge seas, lakes or running water such as rivers, streams and a fork between them, or to enter the form of fountains and springs, and the springs and the eyes are intrinsically groundwater, that is, they water stored in large soil or small meetings of water, be occupied space in the soil as a water reservoir, can find their way through some of the holes caused by earthquakes or earthquakes, or the excavations conducted by Man, they come out of the land rush to the surface forces vary up to breakneck speeds is called the explosive name springs, obtained their diploma are slow water bodies as lakes or small quiet ponds, we can find these sources everywhere even in the desert, which, if found in the desert that called the area around the oasis, and can not go out and remain stored in the ground and are able to do for them -mêmes underground corridors are similar in terms of rivers and streams principle that we see on the surface of the earth. These springs are generally fed from rainwater that penetrate the surface of the Earth and are deposited in the water problem in the communities which is the case when the water collected in dams, for example. And groundwater is underground, where they found wealth, because it is intrinsically pure and fit for human consumption than others and rely on some countries in the financing of water for the state.
