This chapter explores the importance of water, its properties, the water cycle, and various uses of water. Water is essential for survival and plays a crucial role in various natural processes.
Properties of water include transparency, colorlessness, tastelessness, and odorlessness.
Water can exist in three states: solid (ice), liquid (water), and gas (water vapor).
Sources of water include rivers, lakes, ponds, wells, and oceans. Water from these sources goes through a process of purification before it can be used for drinking and other purposes.
Water cycle is the continuous movement of water between the Earth's surface and the atmosphere. Different stages of the water cycle include evaporation, condensation, precipitation, and collection.
Precipitation is the process by which water falls from the atmosphere to the Earth's surface in the form of rain, snow, sleet, or hail.
Different forms of water storage: groundwater (water stored below the Earth's surface in aquifers), surface water (water present in rivers, lakes, and ponds), and atmospheric water (water vapor in the atmosphere).
Uses of water in daily life include drinking, cooking, bathing, washing, irrigation, and generating electricity.
