Biogeochemical Cycle by; sophie swint

  • The Water Cycle shows how water is moved through the earth and atmosphere, to th clounds, then back to earth.

Below is a short video to exlain more:

How Chemicals Affects the Water Cycle:

  • The water we use at home typically end su in a water treatment center, the soaps, dyes, and shampoos can pollute the water.
  • Debris from the street is left and when it rains the water fluhed the debris into a storm drain which eventually leads to our oceans.
  • gases rom cars and trucks pollute the air and oil from car drain onto the ground anf will get mixed ith water when it rains, once its evaported the polluted water s lifed to te air.
  • when it will rain the pollutants are precipated back to natural forns, acid rain forms.

STEPS: (in order)

1) Evaporation- the beginning stage. water is absorbed by the heat engery from the sun which chages the liquid to vapors.

2) condenstaion- after the watr is turned to vapors high pressures change into ice or water particles and the pressure temperature will decrease. these particles will make clouds or fog.

3) Sublimation- this is the process where ice immedantly changes t wator vapors wthout changing into a liquid, this process is slower thane vaporation.

4) Precipition- (rain, sleet, snow, or hail) when water droplets form tother they make bigger droplets, if the temperature is below 0 degress the water will chnage to snow, icem or hail.

5) Transpiration- similair ti evaportion, but the water is turned into vaopr by plants. the roots absord the water through the roots and moves trowrd the leaves and waits for photosynthesis.

6) Runoff- water runs off from a surfaces of the earth. when water runs acoss the grounds it pick up various minerals from the soil. runoff ends uo in lakes, oceans, and rivers,

7) Infiltration- the excess water that does not runoff into rivers and is absored by plan

  • Humans life affects the water cycle by take down trees, using fetilizers that can pollute rainwater, and leaving dangerous item be to sweep away and led to the ocean.
  • The Carbon Cycle is a cotninous cycle where carbon from plants to produce photosynthesis goes to the animals when thet eat them, then returns to the air form respiration.

real video below:

this video is a complete joke but i had to use it.

  • the Carbon cycle in order:
  1. carbon enters inot the air by respiration and/ or combustion, which meand wither carbons enters from ether breathing or a fire/other chemicals
  2. The carbon dioxide is taken up animals and plants (producers), which will eventually make carbohydrates for a process calle photosynthesis.
  3. the animals that take up the carbon then eat the plants, carbon dioxide is taken up whn the animal breathes. (eventaully both plants and animals die)
  4. finally the dead animals and plants are eaten by decomposers and thecarbon that is once in the plants and aniamls is now back in the air to start the whole process over. the decomposed plants and animas become a fossil fuel for future combustion.
  • facts:
  1. organisms can hold carbon in them for many years (carbon sinks)

2. 99% of carbon is within earths surface

3. carbon can be combined with up to 4 compounds at once

  • The Nitrogen Cycle is when nitrogen is converted into different chemical forms that will roam and circulate throughout the atmosphere.
  • Nitrogen Cycle in order:
  1. Fixation: when bacteria converts nitrogen gas into ammonia
  2. Nitrifiation: the process that take the ammonia and changes it nitrate ions so plats can tak in some nutrinents
  3. Ammonification: once the living organisms use up the nitrogen and bacteris changes it from nitrogen rich to simpler compunds
  4. Dentrification: the final step in the process where the simple copounds are released back inot the atmospher fr the cycle to begi again.


  • the nitrogen cycle is one of the most important because it explains the way nitroge moves trhough the atmposhere
  • 78% of the atmposhere is made of non-usable gases
  • in most cases, human have the abiity to alter the cycle when fertilixers are used which gives extra nitrogen to the soil
  • when too much nitrogen is sed, this can cause acid rain
  • the Phosphorus Cycle is a cycle that explains how phosphorus moves through te biosphere, lithosphere, and hydrosphere.
  • phosphorus is able to move through soil, rocks, plants, and other sediments.
  • as the cycle goes weathering will take place and start to break down the sediment.
  • the rocks will tem rlease phosphate and is distributed through soil and water.S
  • phosphorus in plants and animals helps them store more energy (ATP, fats)

overtime as rocks erode they are carried ot the ocean or other bodies of water, there phopsate id relased and setteles in the water. eveuntially it will move throught soil and various sediments and organisms. the cycle will them start over.
