The Water Cycle

The Water Cycle-This is the cycle that processes how the water circulates between earth's oceans,atmosphere, and land. This includes precipitation which is where snow,sleet rain,or hail falls to the ground.The next one included was evaporation which is where a liquid turns into vapor.Lastly there is transportation which is where the water moves through the atmosphere. Organic compounds are amino acids, peptides, proteins ,and nucleic acids. Inorganic compounds are man made fertilizers and ammonia.

Chemical Reactions: There are no chemical reactions involved in the water cycle.

Organic and Inorganic Compounds: Organic compounds are amino acids, peptides, proteins ,and nucleic acids. Inorganic compounds are man made fertilizers and ammonia.

Water Cycle: This shows how the water cycle works. The red arrows show the pathways of movement. Than I drew and labeled all the different parts of the water cycle.

There is a lot of human impact on the water cycle one is withdrawing we are constantly withdrawing water for a variety of different things.

The Carbon Cycle

The Carbon Cycle:Is a series of processes by which carbon compounds are released into the environment. The involves the incorporation of carbon dioxide into living tissue. This can happen because of photosynthesis. Photosynthesis is where green plants and other organisms use sunlight to synthesize food from carbon dioxide. And its return back to the atmosphere happens because of respiration. Respiration is the process in living organisms involving the production of energy. It also uses the decay of dead animals, and the burning of fossil fuels to return the carbon dioxide back into the atmosphere.

Chemical Reactions: Cellular respiration and photosynthesis are the biggest chemical reactions in the carbon cycle.

Organic and inorganic components. Inorganic components are carbon dioxide and methane. Where organic components are forest trees, soil, and peat deposits.

In this picture it represents how the carbon cycle works. The gray arrows show the pathways of the carbon cycle. Than I drew and labeled all the other parts.

Human impact the carbon cycle through the burning of fossil fuels deforestation ,and other poor agricultural practices.

Nitrogen Cycle

The Nitrogen Cycle:the series of processes by which nitrogen and it's compounds are released into the environment and living organisms.This happens because of nitrogen fixation and decomposition. Nitrogen fixation is the process where N2 is converted ammonium or NH4+. And decomposition is the decomposing of living things .

Chemical Reactions: There are a few chemical reactions with the nitrogen cycle. The first one is nitrogen fixation where nitrogen in the air is combined with hydrogen gas to create ammonia. Another one would be nitrification change of ammonia and ammonium into nitrates.

Organic and inorganic compounds in the nitrogen cycle. The organic compound would be hydrogen this converts into ammonia. And inorganic compounds are ammonia as sole N sources.

Humans have a lot of effect on the nitrogen cycle. The main two things they do is deforestation and burning of fossil fuels.

In this picture the nitrogen cycle is shown. I used black and grey arrows to show pathways. I then drew the other parts of the cycle including a cow, tractor and building.

Phosphorous Cycle

Phosphorous Cycle is a biochemical cycle that shows the movement of phosphorous throughout the lithosphere,hydrosphere, and biosphere.It also shows the function, need, and where it lives. It also show what part of the earth uses which part of the phosphorus cycle.

Chemical Reactions are substitution reactions,oxidation reactions,addition reactions,elimination, oxidative.

Inorganic compounds are phosphate ions and other minerals. Where organic compounds are molecules such as DNA.

In this picture it shows the cycle of phosphorus. The black arrows show the pathways in the cycle. The rest of the diagram I drew to show the rest of the cycle.

The main human impact is by humans using fertilizer and raising live stock.
