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).
Explain the three main process involved in the water cycle First, water evaporates from lakes, streams, and oceans and risen into Earth's atmosphere. As water vapor rises, it cools and change back into a liquid. Second, when water vapor condenses, it forms clouds. Third, water droplets combine to form larger drops that fall to Earth as precipitation Put these atmospheric layer in the correct order 1- closest to the Earth's surface, 5 - farthest from the Earth's surface
