1.3-POLYMER FIBER REINFORCED CONCRETE:-Civil structures made of steel reinforced concrete normally suffer from corrosion of the steel by the salt, which results in the failure of those structures. Constant maintenance and repairing is needed to enhance the life cycle of those civil structures.
The water cycle, air pressure, and weather are actually very closely related. The water cycle is the process of water being drawn up from the ground into the sky, where air pressure is lower. (Pressure gets lower as altitude increases, since there is less air available to press down).
Rock Cycle: The Marriage of Water and Rock. Everything in the Biosphere is part of one system, so Rock Cycles could be discussed under Circles as well as under Biosphere. The Water Cycle and the Rock Cycle are closely interlinked, as if they were partners in a long marriage. Everything really is connected to everything else. The creation and movement of rock around the earth is the rock cycle. It is a very slow process that happens over millions and millions of years. People have been finding fossils of ocean creatures high up in the mountains for hundreds of years. How they got there was once a great mystery of science.
