The document discusses the states and properties of water and air. Water can exist as a solid, liquid, or gas, and takes the form of ice, water, or vapor. It has no color, taste, or smell. Air is a mixture of gases including oxygen and nitrogen. Air masses can move as calm breezes, strong gales, or violent hurricanes. The water cycle involves evaporation of water from oceans, condensation into clouds, and precipitation back as rain, snow, or hail.
