Even bacteria needs moisture to grow, so without water these things would not be on the earth. Earth itself would be totally dead with no water. With nothing growing, the soil would be very dry and turn into rocks or dust. Even the air would be affected. Temperatures would either be extremely hot or cold with no moisture. Water heats up the earth when it is cold and cools it down when it is hot. There wouldn’t be anything that would help against earthquakes or put out fires. It also cools down the heat that volcanoes release. Water also provides transportation. It carries nutrients and soil to other parts of the environment. It also helps transport goods to other parts of the world.]]> 2018-04-27 15:48:41 UTC https://padlet.com/19petem1/6dbhaimz6l2m/wish/256064665 19petem1 https://padlet.com/19petem1/6dbhaimz6l2m/wish/256065066

Humidity - The amount of water in the atmosphere. As water molecules evaporate into the air, humidity increases. When the air holds all the water vapor it can at a given temperature, the air is saturated. The amount of water vapor air can hold increases with temperature increase.

Relative humidity (RH) - how full the air is of water. Since warm air expands it can hold more water, lowering its relative humidity. Relative humidity is calculated by dividing the actual amount of water vapor in the air by the saturated amount the air can hold at that temperature and multiplying that value by 100 to get a percent.

Water is constantly going through phase changes which is how it switches between the phases of solid, liquid, and gas. Each phase change has a specific name. Solid to liquid phase change is called melting, liquid to gas is evaporation, solid to gas is sublimation, gas to solid is deposition, gas to liquid is condensation, and liquid to solid is freezing. These phase changes are what allow water to exists in oceans and lakes, in the atmosphere, and in ice. When water is in solid form, each individual water molecule is tightly packed in a uniform fashion in order to form the solid. In liquid form the water molecules are somewhat packed but there is space between each molecule. In Gas form the water molecules are far apart and are moving very fast.]]> 2018-04-27 15:50:45 UTC https://padlet.com/19petem1/6dbhaimz6l2m/wish/256065565 19petem1 https://padlet.com/19petem1/6dbhaimz6l2m/wish/256065969

Cloud seeding is a way to alter what clouds produce and how much of it as well. For example, modifications are made to either stimulate precipitation. These alterations are just chemicals like iodide to create ice particles within clouds. Salt water and dry ice are used as well. Iodide is used for cold cloud seeding while salt water and dry ice are used for warm cloud seeding. In order for cloud seeding to work, the chemicals with attach themselves to the water molecules within the clouds. Snow is produced in the cold cloud seeding while rain is produced in the warm cloud seeding.
