Water cycle 1. how is water stored on earth during the water cycle? 2. water moves into the atmosphere through and and returns to the earth through 3. what is the difference between infiltration and runoff? 4. where do groundwater and runoff usually end up? 5. what are three ways global warming might affect the water cycle? carbon cycle 1. why is carbon important? 2. what are seven places that carbon exists? 3. how does carbon enter the biotic part of the ecosystem, namely plants from the atmosphere? 4. how does it enter the soil? 5. how does carbon enter water? how do aquatic plants get carbon? 6. how do animals get carbon? 7. what are two ways carbon returns from animals into the water? 8. what is combustion, and how does it affect the carbon cycle? 9. how does deforestation affect the carbon cycle? nitrogen cycle 1. why is nitrogen important? 2. how is nitrogen from the atmosphere, the abiotic part of the ecosystem, converted in to the biotic part of the ecosystem in organisms? 3. how do consumers get nitrogen? 4. how does nitrogen return to the atmosphere? phosphorus cycle 1. why is phosphorus important to living organisms? 2. how is the phosphorus cycle different from the nitrogen or carbon cycles

Water Cycle - 1. Water is stored on Earth in oceans, lakes, rivers, underground, caves, and everywhere that have water naturally. 2. Evaporation (vaporization), Condensation (cloud), Precipitation (snow, rain, hail, fog, sleet, etc). 3. Infiltration is when water go into the ground, runoff is when water either went into the process of infiltration or to the ocean, imagine an avalanche (it is a similar concept). 4. Groundwater sometimes ended up in wells, or remain in the ground until someone dug it out, runoff either end up in ocean or ground depending on where. 5. Well, global warming can cause many flooding from frequent raining and icebergs melting. It can also cause more frequent evaporating which can leave many areas with less water than what they already have. Carbon Cycle - 1. Carbon is important because the whole world needs it. 2. Carbon exists in the atmosphere, deep ocean, soil, animals, humans, surface ocean, plants, and factories. 3. Photosynthesis. 4. Carbon enters the soil when plant or animals dies and goes through decaying process. 5. Water does get carbon from the atmosphere more than land does. Some aquatic plants get carbon by sticking its leaves out of the water. 6. Animals get carbon when it eats plants. 7. When the animal dies, carbon goes back to the atmosphere, then water snatches it back down. Or when they urine. 8. idk 9. Because we get oxygen from plants, and if deforestation occurs more often, there may won't be a plant capable of producing bajillion of oxygen in a span of time. 

The speed of  sound:   sound travels  at different speeds depending on what it istraveling through. of the three mediums (gas, liquid, and solid)  sound waves travel the slowest through  gases, faster  through  liquids, and fastest  through  solids.
