Speaker: Hi kids, this one is for you. It's all about how the water cycle works. The water cycle is a cycle by which water rises, force, flows, and goes. There are many important aspects of the water cycle, and these aspects can effect our daily lives, including our garden. Here are six things you should know about the water cycle.
The first one, is that it's a close system. Normal water is made or destroyed. What implications does that have on our gardens? This means, the water we use from our garden hose, should be used to its fullest capacity. Being prepared for weather, and weather changes is important. If the forecast calls for rain, waiting could be better for the plants, than using up all that water. Conservation matters in the usage of water. The water cycle can be interacted by pollution. By polluting, you are taking away more water that could be used for crops and living creatures. It is why it is imperative, very important, that controls up put in place, to crub pollution from ever occurring in the water cycle.
Usable water, only a small percent, about 1% is usable by living creatures. Of all the water on earth, about 97% is salt water, which is unusable for living creatures. Of the fresh water, three forth of that is locked in the icecaps, frozen and unavailable for living creatures. Then there is a possibility of pollution and getting the water to land, to be used. All states of matter, water is easily found in all states of matter. Gas, think about water vapor in the air. Liquid, water and solid, ice, glaciers etcetera. Where plants will find water and gas perhaps? The liquid form is best for the garden. Water also freezes at 32 degrees Fahrenheit. Plants don't have a regulation mechanism like we do. It's the reason why most plants don't survive frosts and freezes. The water inside the plant would basically freeze, and little water could move throughout its system. There are four important words that you should know. Evaporation, Condensation, Precipitation and Collection. Four words that are most important in the water cycle.
Evaporation is water leaving its liquid state and transforming to a gaseous state. It plays an important part in the water cycle, and it's how water gets from the ground into the sky, and into rain eventually.
Condensation is the cooling of the gaseous water, as it transforms to the liquid state. It is important, because it's proved that water does go through a cycle. Living creatures need water and condensation, and it's what helps to get that water to the form most living creatures can use.
Precipitation is simply the water falling from the clouds or from air, as condensation transforms it. Rain is another form of precipitation.
Collection is how the water is collected when it settles. It is usually collected in clouds, streams, rivers and the ocean. Sweat is a type of evaporation and condensation process. Human sweat, and so do some other animals, plants sweat too. They give off water. Sometimes in a high heat, they can give out too much water. That is why we have to supplement the garden with water, especially in hotter climates and temperatures. So remember, that plants sweat too, and they need water on those hot days.
Conservation means the act of saving of something. Water needs to be conserved, because it's a closed system, and normal water is made or destroyed as I said before. We have all the water we are ever going to get. Conservation of water means, helping to keep pollution at a minimum at worst. As best, we need to avoid pollution in any form. Conserving water in the garden can seem to be a hard task. Fluctuations in climate and temperature can make it frustrating, to know whether the garden will need a supplemental water or not.
There are other things that can be done to help with conservation of water. Mulching, putting down wood chips or other biodegradable materials, such as newspaper and recyclable cardboard, can help conserve or hold in moisture longer. So that water is kept at a minimum and not wasted. The water cycle not only effects the way we live, it effects our gardens. Learning about the water cycle can better our understanding of the garden, and help the make the earth, a more pleasing place to live.
