Summary #4: Cycles of life

Examples of cycle important in the planet:

• Water cycle: the continuous movement  of water between Earth's  surface and the air, changing from liquid to as to liquid. Here in the water cycle alsso we find the freezing and melting point You can start in any place in tis case I gonna start in  evaporation-can be salty and fresh water: salty= beach, ocean etc. they evaporate more fast. 1. evaporation: liquid to gas, heat is absorb. 2.condesation: gas to liquid 3. precipitation can be. snow, rain, hail,sleet  3. freezing: liquid to solid  the heat is released. 4. melting: solid to liquid the heat is absorb.Also happen the runoff and transpiration that when the plants released the water that they have (they evaporate)
• Carbon cycle: the continuous transfer of carbon between the atmosphere and living things. Here you see the oxygen and carbon dioxide in the case of the plants they take the CO2 and produce O2. A car exhaust produce CO2 that is sometime very bad in our enviroment, death decay storage  produce CO2 animal and photosynthisis produce oxygen.
• Nitrogen cycle: the transfer of nitrogen from the atmosphere to plants and back to the atmosphere and directly into plants again, they start with the descomposition of animals or plants then came the ammonia, the bacteria, nitrites go to the plants, the plants absorb the nitrites also some animals then the denitrifying bacteria the go to the atmosphere (the air) and start again.
